TECHNICAL FIELD

The present disclosure relates generally to subsurface equipment that is at least partially manufactured using additive manufacturing, such as 3D printing, and more specifically, to a printed subsurface tool having a metal diaphragm.

BACKGROUND

A subsurface tool that forms a portion of a tubing string, such as a sliding door sleeve tool, often includes annular seals. The annular seals that fluidically isolate an interior passage of the tubing string from an annulus formed between the tubing string and a casing string in which the tubing string extends. The seals also hold a pressure differential between the tubing string and the annulus. When subjected to high temperatures or other conditions, the seals may degrade or the performance of the seal may be otherwise affected. When the seals are individual components of the sliding door sleeve tool and must be assembled with other components to form the sliding door sleeve, errors in the assembly may occur. Generally, it is desired to reduce the number of components in the subsurface tool.

The present disclosure is directed to printed subsurface equipment, such as a printed subsurface tool having a metal diaphragm.

DETAILED DESCRIPTION

Illustrative embodiments and related methods of the present disclosure are described below as they might be employed in a printed subsurface tool having a metal diaphragm and method of operating the same. In the interest of clarity, not all features of an actual implementation or method are described in this specification. 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 developers' 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 nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure. Further aspects and advantages of the various embodiments and related methods of the disclosure will become apparent from consideration of the following description and drawings.

The foregoing disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. Further, spatially relative terms, such as "beneath," "below," "lower," "above," "upper," "uphole," "downhole," "upstream," "downstream," and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the apparatus in use or operation in addition to the orientation depicted in the figures. For example, if the apparatus in the figures is turned over, elements described as being "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" may encompass both an orientation of above and below. The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly.

FIG. 1 is a schematic illustration of an offshore oil and gas platform generally designated 10, operably coupled by way of example to a printed subsurface tool having a metal diaphragm according to the present disclosure. Such an assembly could alternatively be coupled to a semi-sub or a drill ship as well. Also, even though FIG. 1 depicts an offshore operation, it should be understood by those skilled in the art that the apparatus according to the present disclosure is equally well suited for use in onshore operations. By way of convention in the following discussion, though FIG. 1 depicts a vertical wellbore, it should be understood by those skilled in the art that the apparatus according to the present disclosure is equally well suited for use in wellbores having other orientations including horizontal wellbores, slanted wellbores, multilateral wellbores or the like.

Referring still to the offshore oil and gas platform example of FIG. 1, a semi- submersible platform 15 may be positioned over a submerged oil and gas formation 20 located below a sea floor 25. A subsea conduit 30 may extend from a deck 35 of the platform 15 to a subsea wellhead installation 40, including blowout preventers 45. The platform 15 may have a hoisting apparatus 50, a derrick 55, a travel block 60, a hook 65, and a swivel 70 for raising and lowering pipe strings, such as a substantially tubular, axially extending tubing string 75. As in the present example embodiment of FIG. 1, a wellbore 80 extends through the various earth strata including the formation 20, with a portion of the wellbore 80 having a casing string 85 cemented therein. Disposed in the wellbore 80 is a completion assembly 90. Generally, the assembly 90 may be any one or more completion assemblies, such as for example a hydraulic fracturing assembly, a gravel packing assembly, etc. The assembly 90 may be coupled to the tubing string 75 and may include a printed subsurface tool having a metal diaphragm 95 (shown in greater detail in FIGS. 2 and 3). However, the tool 95 is not limited to use with the completion assembly 90 and may be located anywhere along the tubing string 75. An annulus 96 is formed between the tubing string 75 and the casing 85.

FIGS. 2 and 3 illustrate a sectional view of the tool 95, which may be a pressure equalizer or a sliding sleeve tool. The tool 95 includes an integrally formed single- component body 100 that has an outer sleeve 105, an inner sleeve 110, a first diaphragm 115, and a second diaphragm 120.

The outer sleeve 105 defines a first passageway 125 and the inner sleeve 110 extends within the first passageway 125 to form an annulus 130 between the outer sleeve 105 and inner sleeve 110. Generally, the tool 95 is disposed axially (i.e. , in a direction indicated by either the numeral 135a or 135b in the FIGS. 2 and 3) between an upper mandrel 140 and a lower mandrel 145 that form a portion of the tubing string 75. As shown, a portion or portions of an external surface of the outer sleeve 105 may form external threads to couple the tool 95 to internally threaded portions of the upper mandrel 140 and the lower mandrel 145 to create a metal to metal seal. Thus, at least a portion of the tool 95 is concentrically disposed within the upper mandrel 140 and the lower mandrel 145. The outer sleeve 105 has an opening or a plurality of openings 150 that are formed therein such that a liquid can flow from the annulus 130 and through the outer sleeve 105 to an area defined in part by an external surface of the outer sleeve 105, such as for example, the annulus 96.

The inner sleeve 110 defines a second passageway 155 and has a first end portion 160 and an opposing second end portion 165. Generally, the first end portion 160 is associated with the upper mandrel 140. At least a portion of the inner sleeve 110 is concentrically disposed within the upper mandrel 140 to form an annulus 170 between the upper mandrel 140 and the inner sleeve 110. A shifting profile 175 is formed by an internal surface 180 of the inner sleeve 110 within the first end portion 140. The shifting profile 175 is configured to couple with a shifting tool (not shown). The second end portion 165 is generally associated with the lower mandrel 145. At least a portion of the inner sleeve 110 is concentrically disposed within the lower mandrel 145 to form an annulus 185 between the lower mandrel 145 and the inner sleeve 110. The inner sleeve 110 has an opening or a plurality of openings 190 that are formed therein such that the annulus 185 is in fluid communication with the interior passageway 155.

A first seal 195 and a second seal 200 sealingly engage both the inner sleeve 110 and the outer sleeve 105 to fluidically isolate the passageway 155 that is formed by the inner sleeve 110 from the first passageway 125, and specifically, a portion of the annulus 130. The first seal 195 and the second seal 200 are axially spaced such that the first seal 195 is adjacent the upper mandrel 140 and the second seal 200 is adjacent the lower mandrel 145. Additionally, the plurality of openings 150 is located axially between the first seal 195 and the second seal 200. In some embodiments, the first and second seals 195 and 200 are bidirectional seals.

The first diaphragm 115 extends between the outer sleeve 105 and the inner sleeve 110 to fluidically isolate a first portion 130a of the annulus 130 from and a second portion 130b of the annulus 130. The second diaphragm 120 also extends between the outer sleeve 105 and the inner sleeve 110 to fluidically isolate the second portion 130b of the annulus 130 from a third portion 130c of the annulus 130. Generally, the first and second diaphragms 115 and 120 are annular, but may form any shape sufficient to form a seal between the outer sleeve 105 and the inner sleeve 110. The first diaphragm 115 and the second diaphragm 120 extend circumferentially from an outer surface of the inner sleeve 110 to an inner surface of the outer sleeve 105. Thus, the first diaphragm 115 is capable of holding a pressure differential between the first portion 130a of the annulus 130 and the second portion 130b of the annulus 130 and the second diaphragm 120 is capable of holding a pressure differential between the second portion 130b of the annulus 130 and the third portion 130c of the annulus 130. FIG. 4 illustrates an enlarged portion of the body 100 of the tool 95. As shown in FIG. 4, the first diaphragm 115 has a radial dimension 115a and an axial dimension 115b. The second diaphragm 120 also has a radial dimension and an axial dimension. Generally, a shear strength or tensile strength of the tool 95 is associated with, and dependent upon, the radial and axial dimensions of the first and second diaphragms 115 and 120. Also, the designed pressure differential of the tool 95 is associated with and dependent upon the radial and axial dimension of the first and second diaphragms 115 and 120. In an exemplary embodiment, the first and second diaphragms 115 and 120 comprise a metal material. However, the first and second diaphragms 115 and 120 may comprise of any material, such as a plastic, composite, or other non-metallic material.

In a first configuration, the outer sleeve 105, the inner sleeve 110, the first diaphragm 115, and the second diaphragm 120 is integrally formed from the single component body 100. Thus, although the annulus 185 formed between the inner sleeve 110 and the lower mandrel 145 is in fluid communication with the internal passageway 155, the second portion 130b of the annulus 130 is fluidically isolated from the interior passageway 155 due to the first and second diaphragms 115 and 120 and the first and second seals 195 and 200. Similarly, although the annulus 170 formed between the inner sleeve 110 and the upper mandrel 140 is in fluid communication with the internal passageway 155, the second portion 130b of the annulus 130 is fluidically isolated from the interior passageway 155 due to the first and second diaphragms 115 and 120 and the first and second seals 195 and 200. As such, the interior passageway 155 is fluidically isolated from the annulus 96. Additionally, the first and second diaphragms 115 and 120 secure the position of the inner sleeve 110 relative to the outer sleeve 105 when the tool is in the first configuration.

FIG. 5 is a sectional view of the tool 95 when the tool 95 is in a second configuration. When in the second configuration, the first and second diaphragms 115 and 120 are fractured (sheared or subjected to a tensile load until failure) such that the inner sleeve 110 is capable of moving relative to the outer sleeve 105. In an exemplary embodiment, the radial dimensions and the axial dimensions of the first and second diaphragms 115 and 120 are a function of the strength of the first and second diaphragms 115 and 120. That is, the required force to fracture the first and second diaphragms 115 and 120 is dependent upon the axial dimensions and the radial dimensions. The load to shear the first and second diaphragms 115 and 120 may be hydraulically or mechanically applied to the tool 95. Moreover, although the first and second diaphragms 115 and 120 are integrally formed with the inner sleeve 110 and the outer sleeve 105 when the tool 95 is in the first configuration, the first and second diaphragms 115 and 120 may comprise a different material than the material forming the inner sleeve 110 and/or the outer sleeve 105. In the second configuration, and when the inner sleeve 110 is moved in the direction 135a by a shifting tool (not shown) that couples to the tool 95 via the shifting profile 175, the plurality of openings 190 is axially aligned between the first and second seals 195 and 200 and adjacent the plurality of openings 150 and thus the annulus 96. Thus, the interior passageway 155 is in fluid communication with the plurality of openings 150 and any pressure differential between the interior passage 155 and the annulus 96 is reduced or eliminated. When the tool 95 is a sliding sleeve door tool, the sliding door is considered to be in an "open" configuration when the tool 95 is in the second configuration and allows for pressure equalization or at least a reduction of pressure differential, between the interior passageway 155 and the second section 130b of the annulus 130 and thus the annulus 96.

FIG. 6 is a sectional view of the tool 95 in a third configuration. When in the third configuration, the inner sleeve 110 is moved in the direction 135b such that the plurality of openings 180 is axially spaced from the second seal 200 in the direction 135b. As such, the first and second seals 195 and 200 sealingly engage the external surface of the inner sleeve 1 10 and the outer sleeve 105 to fluidically isolate the passageway 155 from the annulus 130 and therefore the annulus 96. Generally, the shifting tool (not shown) will shift, or move, the inner sleeve 1 10 in the direction 135a to "open" the tool 95 and move the inner sleeve 115 in the direction 135b to "close" the tool 95 any number of times as the first and second seals 195 and 200 fluidically isolate the annulus 125 from the annulus 185 and the annulus 170 and therefore fluidically isolates the annulus 96 from the interior passageway 155.

Exemplary embodiments of the present disclosure may be altered in a variety of ways. For example, one or both of the first and second seals 195 and 200 may be positioned in the annulus 130. That is, the seals 195 and 200, or a portion of the seals 195 and 200, may be concentrically disposed between the outer sleeve 105 and the inner sleeve 1 10. In some embodiments, the inner sleeve 1 10, the plurality of openings 150, and the second diaphragm 120 is omitted. Instead, the first diaphragm 115 extends across the interior passageway 125 to form a solid disc to fluidically isolate one portion of the interior passageway 12 from another portion of the interior passageway. The tool 95 is not limited to a sliding sleeve door tool or a pressure equalizer, but may be any tool adapted to fluidically isolate two areas.

In an exemplary embodiment, the tool 95 acts as a pressure seal between the annulus 96 and the interior passageway 155. As the body 100 of the tool 95 is integrally formed, the number of components needed to assemble the tool 95 is reduced. This reduction of components simplifies the manufacture of the tool 95 and reduces cost associated with the manufacture of the tool 95. Moreover, the reduction of components simplifies, reduces, or eliminates assembly of the tool 95 in the field, which may reduce or eliminate assembly errors made in the field. When the first and second diaphragms 1 15 and 120 are comprised of a metal, the tool 95 may be used in a variety of environments in which an elastomer and/or thermoplastic would normally quickly degrade. For example, in high temperature environments, first and second diaphragms 115 and 120 comprised of a metal material may be used in place of elastomer and/or thermoplastics. Additionally, when the first and second diaphragms 115 and 120 are comprised of a metal, the tool 95 may be capable of withstanding a pressure differential greater than a tool having plastic or non-metallic seals. In an exemplary embodiment, the radial and the axial dimensions of first and second diaphragms 115 and 120 are adjustable and can be designed to tailor a desired shear strength or tensile strength associated with the tool 95. In an exemplary embodiment, the tool 95 can have either large flow rates for sliding sleeve door operations or small flow rates for equalization across a plug. Additionally, as the tool 95 or a portion of the tool 95 is printed, complex internal geometries may be formed, such as for example, the second portion 130b of the annulus 130.

In one or more exemplary embodiments, the instructions may be generated, using in part, advanced numerical method for topology optimization to determine optimum dimensions of the tool 95.

During operation of the system 350, the computer processor 370 executes the plurality of instructions that causes the manufacture of the tool 95 or a portion of the tool 95 using additive manufacturing. Thus, the tool 95 is at least partially manufactured using an additive manufacturing process. Manufacturing the tool 95 via machining forged billet stock or using multi-axis milling processes often limits the geometries and design of the tool 95. Thus, with additive manufacturing, complex geometries— such as the first and second diaphragms 1 15 and 120— are achieved or allowed, which results in the creation of complex internal geometries within the tool 95. In one or more exemplary embodiments, the use of three- dimensional, or additive, manufacturing to manufacture downhole equipment, such as the tool 95, will allow increased flexibility in the strategic placement of material to retain strength in one direction but reduce strength, or weaken the tool in another direction.

Thus, a subsurface tool adapted to extend within a wellbore has been described. Embodiments of the tool may generally include an outer sleeve defining a first passageway; an inner sleeve disposed within the first passageway to form an annulus between the outer sleeve and inner sleeve; and a first annular diaphragm extending between the outer sleeve and the inner sleeve to fluidically isolate a first portion of the annulus from and a second portion of the annulus; wherein when the tool is in a first configuration, the first annular diaphragm is integrally formed with the inner sleeve and outer sleeve. Additionally, an apparatus has been described.
