CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Patent Application No. 16/689,382 filed on November 20, 2019 and U.S. Provisional Application No. 62/773,866 filed on November 30. 2018, the entire disclosure of which is expressly incorporated herein by reference.

BACKGROUND

[0002] The oil and gas industry uses multilateral junctions for the development and production of lateral wells, i.e. hydrocarbon reservoirs. A multilateral line integrates with a main bore well line at the multilateral junction. This integration point, per industry standard, is required, in some applications, to be pressure tight and functional to open, close, and choke the lateral fluid flow. Traditional multilateral junctions, however, suffer from a design limitation. The traditional pressure tight multilateral junctions are multi-part components, e.g. a main block, which comprises a main bore, and a lateral junction tubing, joint, and seal. For a pressure tight multilateral junction, there are traditionally two ways of achieving branch control or being able to shut in a lateral. One is to have a flow control device installed in either a main bore or lateral below the junction y-block. The flow control device can be operated to isolate or choke the flow from either the lateral or main bore depending on the application and setup. Another way is to install flow control devices above the junction y-block. This means that the two flow streams must be segregated through the multilateral junction, by for example installing a seal assembly into a polished bore receptacle (PBR) that is attached to either the main bore side or the lateral side of the y-block. Inherently, such a design will only have mechanical access with intervention tools (wire line or coiled tubing) to the side with the PBR attached. The method by which the PBR is attached into the y-block will introduce a geometry that restricts access further, i.e. having a“kink” that reduces the effective inside diameter (ID). A ball, e.g., could roll through but a long and rigid tool with the same outside diameter (OD) would not be able to pass because of the kink.

DETAILED DESCRIPTION

[0012] While the making and using of various embodiments of the present disclosure are discussed in detail below, it should be appreciated that the present disclosure provides many applicable inventive concepts, which can be embodied in a wide variety of specific contexts The specific embodiments discussed herein are merely illustrative and do not delimit the scope of the present disclosure. In the interest of clarity, not all features of an actual implementation may be described in the present disclosure. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developer’s specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0013] A particular challenge for the oil and gas industry is developing a pressure tight TAML (Technology Advancement of Multilaterals) level 5 multilateral junction that can be installed in 7 feet and 5/8” casing and that also allows for ~3 feet and 1/2” ID access to a main bore after the junction is installed. An additional challenge is that the multilateral junction should be able to hydraulically isolate the lateral branch during, e.g., stimulation operations of the main bore or shut off lateral production. This type of multilateral junction could be useful for coiled tubing conveyed stimulation and/or clean-up operations. It is envisaged that future multilateral wells will be drilled from existing slots/wells where additional laterals are added to the existing well bore. If a side track can be made from 9 feet 5/8” casing, there is an option to install a 7” or 7 5/8” liner with a new casing exit point positioned at an optimal location to reach undrained reserves. There are currently no existing level 5 multilateral junctions that offer the possibility to hydraulically isolate the lateral without additional completion equipment, such as seal assemblies and valves. This constraint will necessarily impose an ID restriction when installed.

[0014] Presented herein is a pressure tight, multilateral junction with an integral flow control device for use in well development and production. The multilateral junction comprises a y- block having a main bore, a lateral bore, and lateral port formed in the y-block. This is a single machined or otherwise manufactured object that includes the bores and the port. A flow control device, or i.e. a port seal member, e.g. a sleeve, is integrated within the main bore. The flow control device may be shifted mechanically by well intervention. Alternatively, the multilateral junction may include a controller to cause the sleeve to move between an opened, closed and chocked position. At least one gasket is positioned between the sleeve and the y-block and configured to hydraulically isolate the lateral bore when the port seal member is in a closed position. Even though the problem described above only referenced 7 5/8” junction systems, the concepts and ideas discussed herein are also applicable to other junction sizes, e.g. 7”, 9 5/8” and 10 ¾”. [0015] Referring now to Fig. 1, illustrated is a diagram of a well site for hydrocarbon reservoir production, according to certain example embodiments, denoted generally as 10. The well site 10 includes a pumping station 12, a wellbore 14, tubing 16A and 16B, which may have differing tubular diameters, and a plurality of multilateral junctions 18, and lateral legs 20 with additional tubing integrated with a main bore of the tubing 16. Each multilateral junction 18 comprises a main bore, lateral bore, and a mechanism, e.g. a sleeve, that can be acted upon to open, close, and chock the lateral bore. The mechanism can be manipulated through a control unit 22 using conventional industry practices, such as wireline, coiled tubing operations, or through hydraulic manipulation, or through more advanced methods, such as wireline or wireless manipulation using electronics and software. The multilateral junctions 18 each can be manipulated separately, all at once, or a combination thereof to stimulate a reservoir and used to draw fluid into the main bore during production.

[0016] Referring now to Figs. 2A-2B, illustrated are cross sectional views of multilateral junction 18, according to certain example embodiments. The multilateral junction 18 comprises an upper assembly 24, a y-block 26, at least one gasket 28, and a sleeve 30. The upper assembly 26 comprises a step down tubing 32 and an actuator 34. The sleeve 30 is positioned inside the main bore of the y-block 26. The actuator 34 is used to cause the sleeve 30 to move from its open position, see Fig. 2A, to its closed position, see Fig. 2B. In one embodiment, the actuator 34 is communicable coupled to control unit 22 and responsive to commands issued therefrom. In another embodiment, the sleeve 30 can be mechanically manipulated using traditional well intervention tools. Alternatively, the sleeve 30 can be manipulated using traditional well intervention tools without the need of the actuator 34. The sleeve 30 includes at least one aperture and the y-block 26 includes a lateral port 36 coupled to the lateral leg 20. In the open position, fluid communication is allowed between the main bore and the lateral leg 20 through the at least one aperture and the lateral port 36. The at least one gasket 28 is positioned on at least one side of the lateral port 36 and between the sleeve 30 and the body of the y-block 26. The at least one gasket 28 creates a pressure tight seal isolating the lateral port 36 when the sleeve 30 is in the closed position. In addition, the sleeve 30 can be adjusted to a chock position, which allows partial flow through the lateral bore. Stated differently, the sleeve can be placed in an equalizing position, which allows partial hydraulic communication to equalize pressure across the sleeve 30.

[0017] The step down tubing 32 is coupled to tubing 16A and the y-block 26 is coupled to tubing 16B using industry techniques, methods, and practices, e.g., male and female threads, collars, welding, gaskets, or any combination thereof. The y-block 26 is configured to couple with step down tubing 32 also using industry techniques, methods, and practices. In an embodiment, the lateral leg 20 is welded to the y-block 28. However, obviously, other industry techniques, methods, and practices can be used. The y-block 26 is a single unit, machined or otherwise manufactured, that comprises a main bore and the lateral port 36. By machining or otherwise manufacturing the y-block as a single entity, a consistent internal diameter of the main bore can be realized over the length of the multilateral junction 18.

[0018] Referring now to Figs. 3A-3B, illustrated are isometric views of the y-block 26, in accordance with example embodiments. Fig. 4 is also an isometric view of the sleeve, in accordance with example embodiments. The sleeve 30 comprises a series of apertures on at least one end 30. In one embodiment, the y-block 40 is a machined part that includes a main bore 40 and a lateral bore 42a. In another embodiment, the y-block 40 is a machined part that includes a main bore 40 and a lateral bore 42b, c. The sleeve 30 when positioned in the main bore 40 in a first setting can be manipulated by the actuator 34 and re-positioned into a second setting. Setting in this context can refer to, e.g., grooves, ridges, flanges, or something equivalent thereto that would allow the actuator 34 to move the sleeve 30 from the different positions. Although, it has been described that the sleeve 30 can be slid from a first to a second position it should be understand that it can also be rotated between positions. Fig. 5 is another isometric view of the y-block 26 coupled to tubing 16A, 16B and lateral leg 20, in accordance with example embodiments. As is illustrated in Figs. 3A and 3B, the profile of lateral port 36a is D-shaped and lateral 36b is circular. The profiles offer the largest flow area and cross sectional area for the junction leg, being constrained in a round tube. The purpose of a specific profile is to make the most use of an available space. Fig. 6 is yet another isometric view of the y-block 26 and sleeve 30, in accordance with example embodiments. [0019] Referring now to Fig. 7, illustrated is a flow diagram of an actuator control algorithm for control unit 22, in accordance with example embodiments, denoted generally as 60. The actuator control algorithm 60 begins at block 62 where an actuator signal or signals is received. In an embodiment, each signal can be encoded to identify the actuator 34. This information, e.g., can be displayed to a site operator. At block 64, a command or commands identifying at least one actuator 34 and a function, such as open, close, and adjust, is received and processed. At block 66, at least one actuator activation signal is sent to at least one actuator 34. The at least one actuator 34 responds by either opening, closing, or adjusting the sleeve 30.
