BACKGROUND OF THE INVENTION

There are innumerable petroleum oil wells bored into the oceanic floor by highly evolved modern technological devices to tap the petroleum ( the crude oil ) reservoirs. Many oil wells are clustered in the Gulf of Mexico, Arabian sea and such oceanic grounds, often traversing a significant distance from the coast line, such wells bored into the ocean floor as deep as a mile from the surface waters, to reach the underground oil containments, also of significant depth from the ocean floor, and spread many miles in area. Oil is collected from the wells into surface tanks in moderate containers, or into receptacles as large as ships.

Historically, the production of petroleum oil from the earth's mantle in the ocean floor has shrouded risk and great hazard to the natural environment that includes both the marine life forms and the terrestrial ecosystem adjacent. The greatest hazard is the ignition of the entrained highly inflammable gases like Methane, causing dangerous fires coupled with the risk of oil spewing and polluting the sea water. Such two man-made calamities at the same time can be uncontrollable with available resources, and utterly devastating to the healthy existence of the earth's planetary life forms. For these reasons, error-proof safety systems in under water bore well digging, and highly trained personnel involved in the said operation are required by law in all countries engaged in significant oil production. Despite such stringent laws, system failures and catastrophic results did occur historically and are still occurring, though derived remedial measures through each 'adverse-event experience' uniquely different from the other in some form or other, are still nascent and less than perfect.

Recent event in the gulf shores of Mexico ( involving BP oil company's oil well, the 'Deep Water

l Horizon' under construction ), wherein the ignition of the entrained Methane gas and its fire that continued unstopped for 36 hours, culminated in the collapse of the surface structure of the oil well, resulting in an ever increasing gusher from the source. Several different attempts from the BP oil company's technological team to contain the spewing geyser from finding its way into the body of water and into the gulf shores had failed, mostly due to the inherently limited robotic attempts involved in a moderately deep aquatic habitat.

As any unforeseen adversity can happen at any time before the completion of the well to its last functional detail, safety measures to weather off such events at any step of the construction have to be in place, before beginning to undertake such operation. This PCT application enumerating a model of 'Subsea Level Gas Separator of Oil Well Effluent' ( SLGOE ) unit includes means and methods to be incorporated, beneficially at the most proximate site about the well, and at the earliest, for dissipating a giant gas bubble in formation so as to keep the rig from being a venue of danger, difficult to contain. This is one of the plurality of diverse measures described in the parent domestic application and also in a similar PCT application ( PCT / US 15 / 00125, with the filing date of November 3, 2015 ) by the Inventor Applicant, said measures however working in synchrony, to weather off any unforeseen event throughout the well construction and well operation. For the information of the said devices otherwise operative, the afore-mentioned applications may be consulted. The original application is also a parent application for yet another PCT, also filed around this date, detailing a 'Detachable Island Rig and its Instant Fire Escape', a subject matter that is contextually relevant to any global community significantly involved in oil- production, said subject matter being also preventive in scope, of otherwise catastrophic and totally devastating consequences, in the event of unstoppable rig-fire.

Many inadvertent and unforeseen consequences were / are inherent to such ventures as the deep sea explorations and the like, shrouded in dangers and never ceasing mystery, and counting always on the tides of nature yet to be conquered by technological sophistication. Accordingly, the Author Inventor is neither legally liable nor personally responsible for any inadvertent errors or for any 'adverse events' difficult to differentiate either as a mere association or as a consequence of the application of the structural and procedural information herein enumerated. Application of this disclosure in different situations, innumerable and unique, is a personal choice. Furthermore, understanding, analyzing, and adapting swiftly as needed, to diverse situations, still remain as the professional discretion, expertise, and the deemed responsibility of the involved company and its associates participating in the day to day practice in the implementation of this invention, in part or as a whole.

BRIEF DESCRIPTION OF THE INVENTION

The present invention is drawn to a devised model of 'Subsea Level Gas Separator of Oil Well Effluent' ( SLGOE ), structured about the vicinity of an oceanic oil well. An 'effluent' herein generally refers to admixed emanations from earth's formation of oil containment. In particular, the present invention is designed to separate the components of gas from the liquid and semisolid crude of petroleum analogs, nearly to a total extent, whereby a highly inflammable gas entrainment is precluded to find its way into the rig, historically a known venue of danger. The instant SLGOE model incorporated into the oil collection system, beneficially most proximate to the well head, shall mitigate the occasional failure of the 'Blow Out Preventer' ( BOP ) to resist the entrained gas under immeasurable pressure, the devised operations of the SLGOE being not to resist such force, but to instantly dissipate it thereof, by a scheme of 'gas diversion' altogether, whereby relatively gas-free elements of petroleum analogs will reach the venue of oil collection receptacles about the rig-site. The invention may not be introduced without the inventor's own endorsement at the outset that its unsurpassed simplicity is its best asset in the unpredictable and difficult to contain aquatic habitat.

In one embodiment, the devised model has means for a diversion tube, directing the well effluent from the main oil-collecting tube about the well head, into a set of 3-4 gas separator tanks located not far from the well. Each gas separator tank has its own oil inlet tube forking thereof from the diversion tube, said oil inlet tube rising few inches into the gas-separator tank, with its terminal creating a fountain-like up flow of oil ( the 'up flow' model ) that gravitates down into the tank, to be maintaining a level optimally lower than the raised terminal, a measure aided through a flow control clamp set forth about the oil inlet tube. Furthermore, each gas separator tank has perforations to its bottom, said perforations letting the down-streaming fountain of crude oil to flow away lower down into yet another compartment having an outlet tube, directing the oil out from the tank. Each tank further has sufficiently large gas outlet pipes in the top, for the gas that is instantly separated in the aerial milieu of the tank to be let off into a separate gas collecting system, leading to gas receptacles, situated in a safe distance away from the rig. The effluent from the gas separator tanks then pass through an Oil passage tank' located lower down, and receiving the oil from the top, wherefrom the oil is let out through a 'siphoning tube' to reach the oil collection system at a higher ground about the well head. The gas separator tanks further contain a

'dispersion' device ( either as a 'coil' or as a 'disc' design ) to disrupt a block to the flow downstream, of liquid and semisolid crude oil of the effluent.

In yet another embodiment, there may be only one tank structured, whereby all the elements in the control and operational measures therein, are effectively minimized.

In yet another embodiment, the SLGOE unit can be built as a 'down flow' model, without any need for crude oil 'dispersion' device. In this SLGOE unit, the structure of two 'gas separation tanks' approximates the 'oil passage tank' described earlier except that the oil effluent directly comes from the oil 'diversion tube' entering at the top and flowing down into the first tank

( the 'down flow' model ). There are large sized multiple gas outlet tubes spread all through the top of the tank to let off the gas that is instantly separated in the aerial milieu of the tank. Oil flows from the bottom outlet tube into the second tank positioned lower, the effluent entering also from a surface level through its inlet tube. It has similar gas outlet tubes, the provision of a second tank ensuring complete separation of gaseous components. The second tank has an incorporated

'syphoning tube' to reach the oil collection unit about the well head.

In yet another embodiment, a hybrid model incorporates both of the foregoing devices.

The SLGOE unit of any model is structured at a lower excavated oceanic grounds, to facilitate the flow of the effluent into the tanks, said unit conventionally built as a 'modular capsule' to be lowered into the ocean grounds, and secured by cementing slab. The invention further provides a model of tubing directed to all the tubular systems, to be having a threaded configuration encompassing the entire lengths, facilitating instant joining or closing of a broken system following a catastrophic event, aided by means of - (1) 'instant joint structures' with complimentary threading, shaped as I, T, J, L, C, U etc.; (2) closing caps with threading, to close a broken system terminal, when system joining is not an option.

DETAILED DESCRIPTION OF THE INVENTION

The following is a detailed elaboration of what was earlier briefed in the section foregoing. A model of 'Subsea Level Gas Separator of Oil Well Effluent' ( SLGOE ). An 'effluent' herein generally refers to admixed emanations from the earth's formation of oil containment,

substantially in its natural form, containing gaseous hydrocarbons like methane, liquid and semisolid crude of petroleum analogs, and produced water, extracted in such natural state, usually through a conduit of 'production tubing'. It is the aim of the device to be functional even before the 'production tubing' is installed, as catastrophic events can happen at this point of well construction yet to culminate to its last functional detail, as was exemplified in the event of the 'Deep water Horizon' oil well blow out under construction; Conforming to what are illustrated in Figure-1 and Figure-2, SLGOE is an unit structured on the oceanic grounds about the vicinity of the well head, particularly designed to separate the gas components thereof, from the liquid and semisolid crude of petroleum analogs. It is configured to mitigate any occasional failure of a 'Blow-Out Preventer' ( BOP ) to resist a giant bubble in formation by an entrainment of inflammable gases under high pressure, never to find their way into the rig, as per past experiences destined to be a natural venue of danger, igniting an incessant fire by an otherwise insignificant spark. The model of SLGOE unit herein described is a general outline of an exemplary prototype model to which technological needs well known to the industry, may be incorporated therein. By virtue of its sheer simplicity of operation coupled with a design wherein 'nothing is left to chance', the SLGOE unit is ideal for its destined function, and can be easily set forth on the oceanic grounds about the vicinity of the well head. The proposed model is distinguished by an

unsurpassed benefit if incorporated thereof at the earliest time feasible and at a site most proximate to the well head, the source of the well effluent in its formation. It is the aim of the device to be functional even before the 'production tubing' is installed, as catastrophic events can happen at this point of well construction, as was exemplified in the event of the 'Deep water Horizon' oil well blow out under construction.

Figure-1, as illustrated, shows such outlined model which is simple in its operation, but is devised to be, as can be seen in the drawing, contrastingly different from the basic model of flow control by a 'valve' mechanism, because such valve mechanism at times failed to contain, and let out the inflammable gases under high pressure. Though the valves are proven ingenious inventions, in certain set ups as in oil wells, at times with immense pressures not elsewhere encountered, the valves inherently lack provisions thereof, to 'resist' these pressures, an example that 'nature 's might ' is yet to be conquered despite the growing technological sophistications. The valves are probably better suited to resist pressures originating from within the narrow caliber conduits, such as a 'production tubing', at least in few instances of unexpected pressures. However, when the innermost casing functions as the oil conduit, as - (1) before a well completion to its last functional detail, a situation similar to Deep Water Horizon Oil Well blow out, and (2) in high production wells, when high oil flow is planned without the well destined for the incorporation of a 'production tubing' - the needed resistance of the BOP to be exerted in both instances, is against a well containment under greatest of pressures. It can be compared to a narrow door controlling a main entry vs. wide gates fully open when the flood of onslaught is naturally through a higher dimension. Most, though not all BOP failures probably happened / happen under such

circumstance. Henceforth, it is prudent that yet another mechanism in conjunction be also set in place, to mitigate the BOP failures and the resulting calamity, especially for a so far

insurmountable situational calamity, before a well completion.

The Figure-1, not drawn to scale, is a schematic 'up-fiow' model of 'Subsea Level Gas Separator of Oil Well Effluent' ( SLGOE ) unit that is to be preferably effectuated on the ocean grounds in the vicinity of the well head, shows the oil diversion tube 70 beyond its origin about the well head. The said tube 70 is structured to further fork into 3 oil inlet tubes 72, each leading into a moderately large metal tank ( preferably in steel ) 74. Typically, the bottom of each tank 74 has wide sieve-like perforations 76 throughout, whereas the top of the tank is fitted with widely configured gas outlet tubes 78. They can be studded all around the circumferential periphery of the top. Such an arrangement of voluminous out flow is highly effective when a giant gas bubble is encountered. Each tank contains a relatively smaller additional compartment 82 below the level of the sieved bottom, and the said compartment is fitted with a large bottom outlet tube 84, its diametric configuration devised to be preferably wider than the incorporated 'production tubing'.

\The forked oil tubes 72 entering the tanks 74 are structured to rise few inches ( about 8-10 ) from the bottom of the tanks, to facilitate a fountain like drop-flow into the bottom of the tanks, as the oil overflows out of the tubes 72. Due to such structural arrangement, as soon as the oil gas effluent enters the tanks 74 through the tubes 72, it over-flows to be tossed into the aerial milieu of the spacious tanks ( the 'up flow' model ), whereby the gaseous components of the effluent are fated to instantly ascend to the top of the tanks, and the liquid and the semi-solid crude to instantly gravitate down as dictated by the laws of natural properties. This separation is instantaneous, in marked contrast with a voluminous column of an effluent occupying the tank ( an otherwise typical model ). In the devised model, even with regard to a liquid gusher, its force is attenuated by the said instant separation of the gases, whatever be their proportion ( as yet deemed to be contributing to the force ), whereby such attenuated gusher can be at least tackled by the surface BOP. The crude of petroleum analogs overflowing down the tubes 72, finds its way through the wide perforations 76 in the bottom of the tanks to the compartments 82 below. The compartments 82 fitted with outlet tubes 84 let the oil out continuously from the bottom. The gaseous components of the effluent rising to the top of the tanks and led into the outlet tubes 78, further flow into a sufficiently large and sturdy common tube, and then into separate gas collection system diverted away from the rig. The gas collection system is connected to specially devised receptacles with provision to deal with gases under high pressures. The outlet tubes 84 from all the tanks join a single collecting tube 86, just outside the tanks.

The tanks 74, to be best suited for their functional demands, should be located at a lower ground than the point of origin of the effluent 'diversion tube' about the well head structure. The lowered ground level is deemed optimal if the terminals of the inlet tubes 72 into the tanks are at lower horizontal level than the generally horizontally originating 'diversion tube'

The separated crude petroleum analogs flowing out into the collection tube 86 are diverted into yet another 'oil passage tank', effectively located at a lower level, wherein the oil from the tube 86 flows down, from the top. From this tank, oil is returned to the main collection tube about the well head, by mechanical means thereof. Such means, for example, are aided by laws of hydraulics, conforming to the 'siphon' principle. In this instance, a tube originates from the bottom of the liquid column of the 'oil passage tank', to then reach a higher level about the well head, directing the return of oil flow by 'siphoning' principles. This incorporated model of 'oil passage tank' completely alienates the gas separation tanks 74 from the 'natural drawing force' ( the latter as an effect of the siphoning principle ), whereby the gaseous components will not be otherwise sucked into the down-stream liquid oil collection system, from the tanks 74. Such 'drawing force' created by siphoning principle is exclusively directed to the 'oil passage tank', in effect, returning the oil to higher grounds about the well head. The 'oil passage tank' is also fitted with optimally sized gas outlet tubes in the top ( to join the main gas collection system ), whereby any gaseous components of significance can be furthermore separated. The gaseous separation is also deemed instantaneous in the devised arrangement of 'down flowing' oil into the 'oil passage tank'. A 'transition tank', also located at a lower level, to receive the well effluent first, and then to direct it to the gas separator tank(s) 74, can also be incorporated into the system to buffer the transition, and further to make needed interventions smoother.

It is obvious that these different functional tanks are arranged stepwise wherever needed, to facilitate the forces of gravity, and once these natural forces are structurally made operational at the outset, they need no further technological mending or monitoring, except what is the 'security routine'. The tubes 72 are fitted with external control on / off devices 73 to stop entry of the effluent into any tank 74, when desired. The control devices 73 can also regulate the quantitative oil inflow in such a manner that the level 80 of the oil in the tanks 74 is kept optimally below the terminals of the tubes 72 under usual circumstances, as shown in the Figure-1. For new wells with very high flow all tanks 74 are operational. When flow slows down, only 1 or 2 functioning tanks are sufficient.

The perforations 76 of the sieved bottom of the tanks 74 are devised to be slightly wider than the diameter of the production tubing, wherein the globs of crude oil that could flow through the production tubing may not be generally expected to block the openings 76.

In yet a different embodiment, there may be only one structured tank 74, wherein all the operative components, control components, and monitoring components, in effect, can be substantially minimized. In this model, the flow control clamp being single, can be structured at the off shooting of the oil 'diversion' tube from the main oil conduit about the well head. The outlet flow downstream yet shall go through the Oil passage tank', and then be returned to the collection . THE HYDRAULIC PRINCIPLES GOVERNING THE SLGOE OPERATIONS

'Water seeks its own level' was the essence of Aristotle's principle long ago. In five words, it had effectively summated volumes. Contextually, the principle was directed to the hydraulics governing the 'siphoning' principle. It connotes that an isolated but connected body of water maintains, in all its containments, the same horizontal level and in effect, water may not be diverted to a higher level thereof, except by means of the 'siphoning' principle. This forms the basis for the SLGOE unit and all its extensions need be located at a lower level than the point of origin of the diversion tube 70 about the well head. It is for the reason that the terminal flows of the inlet tubes 72 are part of the isolated body of water, yet connected to the point of origin of the diversion tube 70 about the well head, and hence will not rise and emanate the fountain flow of this 'up flow' model, unless the tubes 72 in their entirety are at or about a lower horizontal level. It is functionally assuring to be at a lower level. The fountain flow need not be a formation of a typical up flowing jet as in the aesthetically configured landscapes, but there should be rise of the effluent column, with a profusion of overflow therefrom. The flow into the inlet tubes 72 are best achieved by the natural forces of gravity in this setting, whereas the flow of the oil up stream, into a higher ground, from the 'oil passage tank', in effect, is best achieved by siphoning principle. It may be understood that the diversion tube 70 shown in the Figure-1, positioned at a lower level than the oil inlet tubes 72, is the most distally drawn oil diversion tubing reaching the tanks, and may not conform to the diversion tubing at its point of origin about, the well head, in a higher ground thereof. One of the fore going paragraphs also contained a related subject matter. Those skilled in the hydraulic engineering are well versed with these governing principles that need no further enumeration.

The ocean grounds may need some excavation to accommodate the SLGOE unit, as it in turn needs to accommodate the Oil passage tank' also, at even a lower level. It should not be hard for the oil explorers, digging even deeper being their expertise. In any model of embodiment, the gas separator tanks 74 will need be provided with a video device and / or a sonar device to monitor the state of affairs within the tanks, and designed to be operated solar battery power source. THE COIL-DEVICE OF THE SLGOE

Optionally, each tank 74 of the 'Subsea Level Gas Separator of Oil Well Effluent' ( SLGOE ) is fitted with a spirally wound 'dispersion coil' unit, preferably in steel, from a top structure of the tank by two rods about a ring structure, the latter attached to its top coil. The

'dispersion coil' 88 of the unit, made of a malleable metal, is designed in an inverted funnel configuration, its bottom coil devised to be the widest, and the uppermost coil the smallest. The 'dispersion coil' unit moves up and down when operational ( in case a block to the downstream oil flow from the tanks 74 is noted or suspected ) , its spring-action with axial downward thrust of all coils disrupting any semisolid crude thereof, blocking the bottom perforations 76 of a tank. The inner diameter of the uppermost coil ( with the smallest diameter of all ) of the spiral is optimally designed to be wider than the outer diameter of the oil inlet tube 72, as the said coil traverses in closest proximity around the tube 72, in its axial motion, when the device is operative. The coil-device can also be operational in continuum at preset intervals that is, about every 5 minute intervals, in effect conforming to 4-5 axial motions each time. With many bottom perforations of the tank, only few of them, if at all, and not all of them, are expected to be blocked at any time. The two supporting rods from the top of the tank attached to the uppermost coil of the device, as illustrated in

Figure-1, are designed to be mostly positioned outside the tank as when the spiral 'dispersion coil' 88 is nearer to the top, whereby the axial motion of the rods conform to external controls, also structured outside the tank.

THE DISC-DEVICE OF THE SLGOE

In yet another embodiment, the coil device of each gas separator tank 74 is replaced by a metal disc device 580, shown in Figure-2. The disc device is preferably made of steel. It consists of a disc 584 with a central aperture 582, the diameter of the aperture configured to be far wider than the outer diameter of the oil inlet tube 72. The disc 584 has an upper surface, and a lower surface, and it is incorporated into a top structure of the tank 74 by two rods 588 attached to its upper surface. The rods 588 are positioned in equidistance, and are designed for axial motion downward and upward in a pre-configured manner at frequent intervals, or as required when a block to outflow of the tank 74 is suspected down-stream. The lower surface of the disc 584 is structured to have multiple spikes 586 located in a positional configuration that corresponds to the position of the bottom perforations 76 of the tank. The cross sectional diameter of the spikes 586 is devised to be optimally smaller than the perforations 76, as, in the axial downward motion of the disc device 580, the spikes 586 are designed to pass through the perforations76 of the tank, wherein any globs of the semisolid crude blocking the perforations are thereby disrupted. The central aperture 582 of the disc is sized far wider, whereby, in the axial motion of the device 580, it. is positioned around the oil inlet tube 72 in an easy accommodating manner, as also to letting an easy ascent of the up flowing gases. The disc-device when operational in continuum at preset intervals thereof, that is, about every 5 minutes intervals, it conforms to deliver a series of 4-5 axial motions each time. The metal disc 584 as devised in the invention has an incline, rather than the flat design, as of a CD-ROM disc. That is, it is supported from the top of the tank 74 like a lamp shade with a little downward incline. In this configuration the semisolid crude of the effluent falling on to the top of the disc 584 in its axial motion about the level of the oil inlet tube 72, will flow down and not settle on the surface, by virtue of the downward incline. In conformity to the function, the spikes 586 that are centrally located about the disc 584 are structured longer, whereby all the spikes in their lower free ends are in a same horizontal plane.

The disc 584 is sized to be not spreading through the whole of the tank top, the gas outlet tubes 78 being positioned to occupy a wide outer circumferential dimension. The rods 588 are devised to be mostly positioned outside the tank 74 as when the disc 584 is nearer to the top, wherein their axial motion is subject to external controls structured outside the tank 74.

In yet another embodiment the disc device 580 is made with hemi structures of the disc 584. In this model, the device otherwise conforms to the similar structural and functional design of the whole disc, except that the complete upward and downward motion of the hemi structures alternate i.e. only after the downward and upward motion of one device is concluded, the other will initiate its downward motion. The design has an added advantage that the semisolid effluent easily slides down from the top of the disc devices. It also facilitates better ascent of the up flowing gases even while the hemi-device is operational.

The outlet 'diverting tube' and inlet 'merging tube' from the well head source itself is facilitated by making provisions for their incorporation about the base piece of the drilling riser, a site past the BOP, so that the occasional failures of the BOP is mitigated by the SLGOE unit. Obviously, the oil collection system about the well head has a complete separation between 'merging tube' and the 'diverting tube'.

The SLGOE unit as a 'down flow' model, without a 'dispersion' device

In yet another embodiment, the SLGOE unit is devised as a 'down flow' model, as shown in Figure-3, not drawn to scale. It is built without any need for crude oil 'dispersion' device. In this SLGOE unit, also made of steel, the structure of the two devised 'gas separation tanks' closely resembles the Oil passage tank' described earlier, however, the oil effluent directly comes from the oil 'diversion tube' 400 off shooting from the 'production tubing' 408, past the well head 402 and the BOP 438, to be entering from the top of the first 'gas separation tank' 404, through an oil 'inlet tube' 406, and the effluent 416 flowing down into the tank 404 ( the 'down flow' model ). The incorporated oil 'outlet tube' 418 at the bottom of the tank 404 is large sized, and there are also large sized multiple gas outlet tubes 420 spread all through the top of the tank. Oil flows from the outlet tube 418 into a second first 'gas separation tank' 424 positioned at a lower level so that the effluent enters also from a surface level of the second tank 424 through its inlet tube 426. The provision of a second tank ensures complete separation of gaseous components. The second tank 424 has an

incorporated 'syphoning tube' 428 rising from the bottom of the oil column in the tank 424, to be let out at the surface, to reach the oil collection unit about the well head 402, as the 'merging tube' 430, joining just above the originating 'diversion' tube 400. Obviously, the oil collection system about the well head 402 has a complete separation between 'merging tube' 430 and the 'diversion tube' 400, as earlier specified. This type of SLGOE arrangement may or may not have a 'transition tank' preceding the said 'gas separation tanks' 404, 424. Large sized gas collection tubes in this context imply that multiple large outlet tubes occupy the whole of the top of the tank, that the diversion of even a giant bubble from these, to reach the bottom of the tank, is extremely unlikely. Such arrangement is precisely directed to the rare occasions when such giant bubbles are encountered.

As the down flowing oil is thrown into the spacious aerial milieu of the tanks just as it was in the preceding 'up flow' model of a fountain, the separation of gaseous

components is instantaneous, and similarly, the completely separated gaseous elements rise to the top of the tanks with great ease ( the gaseous elements originate in the top of the tank to start with, as an added advantage ). Sufficiently large sized oil inlet and outlet tubes herein designed ensure no obstruction to the nil flow anywhere in the system. The originating oil diversion tube about the well head has flow control clamp, so as to precisely control the flow at any time. As in the preceding model, the gas separator tanks will need be provided with a video device and / or a sonar device, to monitor the state of affairs within the tanks, and designed to be operated by solar battery power source.

In the devised models, subject to be tossed and free flowing into the aerial milieu of a spacious tank, the gaseous elements are fated to instantly ascend to the top ( unlike a continuous steady admixed column of the conventional separation tanks, if any, or with no gas separation device incorporated at all ), and the liquid and semisolid crude instantly gravitate down, dictated by the known laws of nature, wherein the separation is instantaneous and reasonably complete. Said designing lets a giant gas entrainment to easily rise up into the gas outlet tubes positioned in the top of the tank, thereby dissipating its force and pressure, whereas if the separation is neither instantaneous nor easy, as in a crowded compact column of the conventional tank designs, if any, substantial part of the gas bubble due to its massive size can instantly entrain into the outflowing oil effluent, meaning, even a few seconds can count, that is, the speed of gas separation and its rapid ascent drastically curtail the giant bubble entrainment reaching the rig, the very large sized multiple gas collection tubes in the tanks further aiding rapid reception and diversion. The hybrid model

For those who are still concerned about the globs of crude oil blocking the tubing, the 'up-flow' model can be partly incorporated into the 'down flow' model of the first 'gas separation' tank. That is, in this 'hybrid model' of the tank, the oil still flows down from the top, but the tank has a perforated bottom, and a lower oil outlet compartment, along with the 'dispersion' device of choice at the top, whereas the second tank and the gas outlet pipes conform to the described design. This yet another embodiment is a better design for them to proceed with peace and secure feeling, whereas for all practical purposes, the 'down-flow' design described in the fore going paragraphs is still a fail-proof plan though seemingly simplistic in an industry where nothing simple is expected. As per the desires of the oil company, any preferred model can be chosen..

The modular protective enclosure of the SLGOE unit

In view of the utmost functional importance of the SLGOE unit, it is prudent that the whole unit is in an enclosed protective structure. It can be easily actuated by structuring the unit in an enclosed 'modular capsule' with an appended 'SLGOE tubular' on one side, the whole unit made of steel in its entirety. With all the inlets and outlets capped, it traverses the ocean's depth, to be deployed onto the excavated grounds about the well head with provisions for secure ground fixtures. The needed stepwise incline of the tanks is configured within the modular capsule, wherein the base of the modular itself conforms to a horizontal structuring, for its easy and secure stationing on the excavated grounds. The 'SLGOE tubular' configured in standardized lengths, is devised for an access to the 'drilling conductor' of the well just above the conductor's base piece, through the upper tenninal of the said tubular, the latter also having reinforcing vertical supports from the ocean grounds. The modular is structured with 'shopping cart' wheels to its bottom, for its precise stationing. The 'SLGOE tubular' having access into a side wall of the 'SLGOE modular' at the lower terminal, is in flush with its base to be also resting on the ocean grounds. The earlier described video and / or sonar monitoring devices will be incorporated into the modular, in addition to their installation within the tanks. The solar equipment power sourcing these monitoring devices is structured outside the modular, ensuring the needed sun exposure. The modular unit has conventional hooked and ringed structures strategically placed in its outer shell, for the needed anchoring manipulations, for its secure stationing. Threading in entirety, of the unit's tubing system, is as described at the end of this discussion.

The whole 'SLGOE modular' unit is stationed at a lower level than the originating 'diversion tube' about the well head, wherein the said 'SLGOE modular' unit encompasses the 'transition tank', the 'gas separation tank(s)', and the Oil passage tank' in the 'up-flow' fountain model, and merely the 'gas separation tanks' in the simpler design of the 'down flow' model, with the terminal

'syphoning tube' incorporated into either model. It may be noted that the tanks of the units as configured can be fairly closer to each other that the modular unit as a whole would be less space occupying on its excavated grounds. The needed excavation can be easily effectuated by dynamite blowing, involving a small area of the ocean grounds, a process well known to those skilled in architectural engineering. It follows, it is a good idea that the ground is prepared for the SLGOE unit stationing before digging the oil well, as it ensures the future well safety. Furthermore, perfect ground stability with no shaken or loosened earth mantle should be ensured in the vicinity and in the site of well digging. In older wells, the unit is planned at a safe distance from the well.

As the oceanic waters about the well head are subjected to the extreme weather conditions of cyclones, storms, and hurricanes as elsewhere in the ocean, the whole of the modular shell is secured by sturdy metal chains on its three sides to the adjacently erected cement slabs built by QUO RETTE, Hydraulic Water Stop Cement ( number 1126 ) with quick consolidating properties and available as above or below grade strengths, suitable for quick setting in 3-5 minutes. Such detachable yet strong anchoring allows a replacement of the unit, when needed.

The excavation of the oceanic grounds is better done as a gradually sloping wide saucer shaped area with central flattening, rather than a small confining cubical tub. The former model provides better visualization, access, and precise wheeling of the modular. Obviously, a cemented path, accommodating the wheels needs to be paved from the periphery to the flattened center of its stationing. The 'SLGOE tubular', in its length, is tailored to the well's geography. As even few centimeters of disparity will be problematic, the approximate length of the tubular should be known, erring for a longer size than shorter, whereas the needed finer adjustments are done at the time of its stationing by manipulating the central flattened ground already excavated. It follows, though the ground is prepared earlier, the stationing of the 'SLGOE modular' is done about the time of deploying the drilling conductor. The drilling conductor above its base piece should have complimentary provisions for articulating with the 'SLGOE tubular'.

Said modular capsule is an added security provision in view of the attainable structural stability to withstand the more than occasional turbulences of the oceanic ecosystem, apart from the attainable easier interventions and easier functional monitoring, in an unpredictable and difficult to contain desolate deep sea habitat.

The Vulcanized rubber as the structural constituent -

It can be noted that all the rubber washers or any assembly devices of rubber incorporated in the oil gas separator models, and in the modular unit, are made of vulcanized rubber, the only type of rubber that can resist the degrading attack of the petroleum analogs.

The Utilitarian merits of the invention, and the incorporation of the unit -

The proposed models as a whole, by any standard, encompass simpler methods that can be effectuated on the oceanic grounds in the vicinity of the oil well, to separate the regularly encountered oil gas mixture, or occasionally encountered greater amount of admixed gas under significant pressure. The target is to mitigate dangerous calamities of gas entrainment rather than 100% refining measures of oil gas separation that is otherwise pursued by the Oil production plants' engaged in exclusive crude-oil separation ( the 'Oil Refineries') by means of the highly involved process of 'Fractional Distillation'.

The SLGOE device is obviously intended to preclude possible entrainment of inflammable gases into the petroleum collection system, and then into the rig thereof, setting up dangerous fire by an otherwise insignificant ignition spark, inherent to the rig for whatever reason. Compared to the enormous resistance exerted by the conventional BOP, the means and method steps described as in the SLGOE units seem too simplistic, but there is an inherent difference that is taken great advantage of, to propose such a model. The principal involved in the BOP is to ultimately resist the well pressure when needed, especially if it is a giant gas bubble of entrained gases

that it can fail to resist, as in the BP's Deep Water Horizon Oil Well blow-out. The SLGOE device makes no effort to contain such gas pressure simply for the reason that at certain thresholds, it is clearly uncontainable. Accordingly, it is prudent to let out such pressure, totally if possible, to reach a different destination other than the rig. In case the pressure is only partially subdued, at least it may be optimized for the surface BOP near the rig level to be able to control, and prevent a blow-out. Obviously, it is generally not a sure plan of the SLGOE device to control a high pressured liquid oil-gusher from the oil well. However, even a high pressured liquid-gusher has admixed gases of any proportion, it is attenuated for the surface BOP to tackle, with its occasional failure possibly precluded.

The SLGOE device can be incorporated into the oil collection unit anywhere in a manner feasible, the ocean grounds about the well head being the most beneficial venue, as thus far emphatically suggested. The oil conduit about the well head, by any suitable means, can be structured to have a diverting oil-outlet tube, and a merging oil-inlet tube, so incorporating the SLGOE unit into the oil collecting system, subject to separating the oil and the gas at the source, at the earliest feasible occasion of the well construction, precluding a giant gas bubble entering the rig at any time through-out the rig operation.

For the BOP to control pressures involving most powerful of ruptures, in all high volume wells where such events can be reasonably expected, it is a worth trying option to divide the oil line into multiple outlet conduits within the innermost casing and each outlet conduit structured to pass through its own stack of BOP, wherein each stack of BOP can tackle the divided power of the gusher, reduced to half, or to one third of its strength. It implies, it is a good practice to never allow a production casing ( the innermost casing ) to be a functioning oil-conduit in high volume wells, a practice that takes out at the outset, probably an unrecognized brewing recipe for danger.

Other incidental utilitarian advantage for the oil companies is - claiming a substantial amount of gaseous components of the well effluent, instead of the 'oil refineries' doing so. Why it is substantial is, once the effluent is thrown into the aerial milieu of the tanks ( including the 'oil passage' tanks ), the gaseous elements can only rise up to the tank to be let out. Only small bubbles intimately admixed with semisolid effluent are left to be separated by the oil refineries. These seemingly unwanted gaseous elements are highly utilitarian for other purposes that the oil companies can also invest on ( which probably they are already doing to some extent ), as indeed they extracted these from the underwater oil containments.

THREADED INSTANT JOINT CONFIGURATIONS AND CLOSING CAPS

The invention further envisions a model of tubing directed to all tubular systems, and their methods of instant system joining or closing, for all future oil exploration units, or as a replacement-tubing for existing units. The model of tubular systems are structured to be having a deep threaded configuration on the inside or the outside, traversing the entire lengths of all the involved tubular systems, facilitating instant joining or closing of a broken or intact system, aided by means of - (1) 'Instant joint structures' shaped as I, T, J, L, C, U, Y etc. with complimentary threading, and having a straight or nested configuration, to be inserted thereto, for the system joining, when a conduit line is broken and interrupted. The middle part of the structures can be enlarged in circumference for easy handling even by the robotic maneuvers; (2) 'Closing caps', also with complimentary threading to be threaded thereto, for closing a tubular system, when system joining is of no option. The structure can have a stem of tubing with complimentary threading to connect, whefefrom it enlarges to a tubing double the size or more, ending in a very sturdy and massive closing cap to resist enormous pressure exerted by the tubular system at the terminal, and the size of the cap ensures easy manipulation, even by the robotic maneuvers.

The tubing involved can be production tubing, oil collection tubing, tubular system involving the rig, the 'Subsea Level Gas Separator of Oil Well Effluent' ( SLGOE ), and any tubing wherein said configuration is deemed effective. Such structural mandate is as important as all the safety devices incorporated thereof, in case 'fire and well surface blow-out' happen, resulting in a 'disconnect' in the system - when instant joining anywhere necessary is accomplished, or else instant closing of the system anywhere necessary is similarly accomplished. The configured joint structures shaped as specified above, are used as one or multiple joints. Multiple I joints are usually needed to aid incorporating other joint structures, to restore a conduit line, or complex interconnections. Said tubing deployed all through the rig structuring and the well designing wherein the SLGOE is incorporated, ensures an immediate restoration of SLGOE functioning, when a tubing system is disrupted for whatever reasons. System upsets at and around being unintended for the vital purposes of SLGOE functioning, it is a pertinent answer to the pertinent inquiry that how best tl materials, methods, and the means plus steps functions limitations are chosen, in an unpredictabl and difficult to contain deep sea habitat, wherein nothing may be left to chance. It was already stressed that such structural mandate is as important as all the other safety devices, put together. Moreover, what needs to be herein implemented is a small step forward in means familiar, however, with a big leap in functions achievable.
