- boreholes are created in a formation believed to harbor a desired resource. Such boreholes are completed using a number of strings of materials and tools to achieve certain control and production requirements. Many different types of completions are in use and have been previously used giving operators a large number of options to develop a completion strategy for a particular borehole system. Nevertheless, the art still continues to seek alternate methodologies, techniques and systems to improve operations by for example reducing cost and time for completion.
- a mechanically lockable and unlockable hydraulically activated valve including a mechanical component having a locked position and an unlocked position, a hydraulic component in operational communication with the mechanical component, the hydraulic component including a portion that is unresponsive to pressure events with the mechanical component in the locked position and responsive to pressure events with the mechanical component in the unlocked position.
- a borehole system including a string disposed within a borehole, the string including a valve.
- a method of operating a mechanically lockable and unlockable hydraulically activated valve for a borehole includes shifting a mechanical component of the mechanically lockable and unlockable hydraulically activated valve from a locked position to an unlocked position, inducing a differential pressure on a hydraulic component of the mechanically lockable and unlockable hydraulically activated valve, opening a hydraulic valve of the mechanically lockable and unlockable hydraulically activated valve.

- FIG. 9 is a view of a borehole system including a number of valves as disclosed herein.
- FIG. 1 a perspective view of a mechanically lockable and unlockable hydraulically activated valve 10 is illustrated.
- the valve employs a mechanical component 12 that is configured to lock and unlock the valve 10 through the action of a mechanical intervention such as a shifting tool or similar.
- the component 12 through interaction discussed further below will prevent a hydraulic component 14 of the valve 10 from reacting the hydraulic pressure when the mechanical component 12 is in one position and allow the hydraulic component 14 to react to hydraulic pressure when the mechanical component 12 is in another position.
- the hydraulic component 14 is configured to respond to hydraulic pressure such as a tubing pressure increase to permit flow through the valve 10 from a source of fluid on one side of the valve to a volume on the other side of the valve 10 .
- the source is outside of the valve 10 such as a formation flowing fluid into a tubing string through the valve 10 .
- Such fluid may come through a screen to remove undesired particulate matter.
- the fluid flow could be in the opposite direction such that fluid moves from the inside of the tubing string out into the formation through the valve 10 .
- the valve itself provides for operational certainty that it will not open due to pressure fluctuation prior to the mechanical component being unlocked and also provides the benefit that the mechanical component 12 can be unlocked when desired without the valve 10 immediately being open to fluid flow.
- the valve therefore provides significant utility enabling other operations while also reducing the equipment needed in the hole and reducing number of runs needed to operate a borehole system.
- Valve 10 includes a body 16 within which mechanical component 12 is movable and upon which hydraulic component 14 is mounted.
- the mechanical component 12 comprises a sleeve 18 , a sleeve extension 20 and a mandrel 22 attached to the sleeve extension.
- the interconnect feature 20 and mandrel 22 may in some embodiments be one piece of material.
- the mandrel 22 extends into a piston housing 24 through seal 26 and through a piston 28 .
- the piston includes piston-mandrel seal 30 and piston-housing seal 32 .
- Piston 28 further includes a mechanical interconnect feature 34 such as a collet configured to create a connection with a valve stem 36 of hydraulic valve 38 under conditions described below.
- the hydraulic valve 38 includes valve seals 40 that seal against valve housing 42 .
- a hydraulic actuation port 44 and a flow port 46 are provided through the body 16 .
- Hydraulic actuation port 44 allows tubing (of which the body 16 forms a part) ID pressure access to a space 52 defined by the piston housing 24 and the piston 28 . Increased pressure in the tubing ID increases pressure in the space 52 resulting in a differential pressure across the piston 28 and accordingly movement of the piston 28 .
- Flow port 46 allows fluid flow between outside of the valve 10 and inside the body 16 , when the hydraulic valve 38 is open. It is also noted that, in an embodiment, a flow path 48 may be defined between a screen 50 and the flow port 46 . It is to be understood however that the valve 10 is not limited to use with a screen.
- valve 10 is runnable into a borehole 54 on a string 56 to a desired location. In some embodiments this will be as a part of a lower completion after deployment of which, other borehole operations might occur.
- One of the benefits of the arrangement disclosed herein is that such other borehole operations may be conducted after installation of valve 10 without concern for inadvertent hydraulic actuation of the valve 10 since the mechanical component 12 prevents such hydraulic actuation until specifically enabled by repositioning of the mechanical component 12 .
- prior art systems required additional equipment and runs to render lower completions installed for similar purpose but of different types than that disclosed herein safe for other borehole operations. These of course significantly increase cost and require additional rig time.
- Valve 10 in FIG. 2A is in the run position with the hydraulic valve 38 closed and locked and the mechanical component 12 locked.
- FIG. 3 provides a larger view and hence should be referred to simultaneously with FIG. 2A in the following discussion.
- the distinction in position or attitude of piston 28 , and a resilient member 58 such as spring in operable communication therewith can be seen between FIG. 2A and FIG. 2B .
- This is due to an increase hydraulic pressure in the tubing ID causing a differential pressure across piston 28 as discussed above.
- mandrel 22 is in contact with valve stem 36 , during this pressure event, two things occur.
- valve stem 36 and accordingly the hydraulic valve 38 are immobile and because the mandrel 22 is in contact with the valve stem 36 , the interconnection feature 34 cannot engage the valve stem 36 and so movement of the piston 28 will not result in any impetus to the hydraulic valve 38 to move.
- This is illustrative of the pressure insensitivity of valve 10 while the mechanical component 12 is in its locked position. When the mechanical component 12 is in the unlocked position, this same activity pursuant to a pressure event, will result in the hydraulic valve 38 moving to an open position (addressed further below).
- a shifting tool is run in the hole to shift the mechanical component 12 to an unlocked position.
- the component 12 is illustrated as a sleeve 18 .
- the shift in position of sleeve 18 can be seen in HG 4 A along with a shift in the position of extension 20 and mandrel 22 .
- the valve 10 is now unlocked and upon a pressure event the hydraulic component 14 will react resulting in opening of the hydraulic valve 38 .
- responsive and “unresponsive” as used herein relate to the hydraulic valve 38 responding to a pressure event or the hydraulic valve 38 not responding to the pressure event.
- FIG. 4B illustrates a pressure event in the unlocked condition. It will be appreciated that the piston 28 is moved as it was in FIG. 2B but that this time, the mandrel 22 is not against the valve stem 36 . Because of this change in condition, the interlock feature 34 , which may be a collet or similar, is allowed to snap closed about valve stem 36 . Notice that resilient member 58 is compressed in FIG. 4B where is it relaxed in FIG. 4A .
- This compression of spring 58 means that upon reduction of the pressure event applied to cause the interlock feature 34 to engage the valve stem 36 , the spring 58 will push the piston 28 back toward the space 52 taking valve stein 36 and thereby hydraulic valve 38 with it such that the valve 10 is in the position illustrated in FIG. 5 .
- the flow port 46 is open in this position allowing fluid flow between the ID of the body 16 and the volume outside of the body 16 .
- the valve 10 is resettable by shifting the mechanical component 12 back to the position shown in FIG. 2A .
- the mechanical component may include a profile 60 that is selected to each valve or is of the same shape for each valve with the purpose of allowing for the shifting tool (not shown) to engage the mechanical component for shifting its position from locked to unlocked or vice versa.
- an indexing configuration 70 allowing for multiple pressure cycles following unlocking of the mechanical component before the hydraulic component will complete its task of opening the hydraulic valve.
- This configuration allows for pressure testing of borehole tools prior to opening the hydraulic valve.
- an indexing configuration 70 such as a J-slot, is disposed in operable communication with the piston 28 .
- the configuration 70 simply replaced a portion of the longitudinal extent of piston 28 . It is to be understood that length is relative and no limitation is intended hereby.
- the configuration 70 interacts with a pin 72 extending from the piston housing.
- the piston 28 Upon pressure events in the tubing as in the foregoing embodiment, the piston 28 is moved leftwardly in the drawing (see FIG. 7 ) causing the configuration 70 to cycle on the pin 72 . This motion will continue daring subsequent pressure and pressure relief events until the configuration 70 reaches a position where the pin is allowed to move further allowing engagement of the interlock feature 34 with the valve stem (see FIG. 8 ).
- the number of pressure cycles for testing purposes prior to opening of the hydraulic valve may be selected at the time of assembly of the tool either by selecting a configuration 70 having the appropriate number of cycles or by positioning a generic configuration 70 so that a selected number of cycles remain before actuation is possible.
- the valve 10 may be used on its own, with a screen, in a multizone configuration as in FIG. 9 , etc.
- a lower completion comprises one or more of the valves 10 . These are run in the hole and deployed there. They will have no effect until a shifting tool is run to unlock the mechanical components, normally carried out after or simultaneously with the deployment of an upper completion. Thereafter, one or more of the valves 10 may be opened pursuant to a pressure event caused by pressuring up on the tubing string that represents the upper and lower completions.

- Referring to
FIG. 1 , a perspective view of a mechanically lockable and unlockable hydraulically activatedvalve 10 is illustrated. In this embodiment the valve employs amechanical component 12 that is configured to lock and unlock thevalve 10 through the action of a mechanical intervention such as a shifting tool or similar. Thecomponent 12 through interaction discussed further below will prevent ahydraulic component 14 of thevalve 10 from reacting the hydraulic pressure when themechanical component 12 is in one position and allow thehydraulic component 14 to react to hydraulic pressure when themechanical component 12 is in another position. Thehydraulic component 14 is configured to respond to hydraulic pressure such as a tubing pressure increase to permit flow through thevalve 10 from a source of fluid on one side of the valve to a volume on the other side of thevalve 10. In an embodiment, the source is outside of thevalve 10 such as a formation flowing fluid into a tubing string through thevalve 10. Such fluid may come through a screen to remove undesired particulate matter. Alternatively, the fluid flow could be in the opposite direction such that fluid moves from the inside of the tubing string out into the formation through thevalve 10. The valve itself provides for operational certainty that it will not open due to pressure fluctuation prior to the mechanical component being unlocked and also provides the benefit that themechanical component 12 can be unlocked when desired without thevalve 10 immediately being open to fluid flow. The valve therefore provides significant utility enabling other operations while also reducing the equipment needed in the hole and reducing number of runs needed to operate a borehole system. - Referring to
FIG. 2A , the individual parts of theFIG. 1 embodiment ofvalve 10 are described and their interaction explained. Valve 10 includes abody 16 within whichmechanical component 12 is movable and upon whichhydraulic component 14 is mounted. Themechanical component 12 comprises asleeve 18, asleeve extension 20 and amandrel 22 attached to the sleeve extension. It is to be understood that the interconnect feature 20 andmandrel 22 may in some embodiments be one piece of material. Themandrel 22 extends into apiston housing 24 throughseal 26 and through apiston 28. The piston includes piston-mandrel seal 30 and piston-housing seal 32. Piston 28 further includes amechanical interconnect feature 34 such as a collet configured to create a connection with avalve stem 36 ofhydraulic valve 38 under conditions described below. Thehydraulic valve 38 includesvalve seals 40 that seal againstvalve housing 42. - Still referring to
FIG. 2A , ahydraulic actuation port 44 and aflow port 46 are provided through thebody 16.Hydraulic actuation port 44 allows tubing (of which thebody 16 forms a part) ID pressure access to aspace 52 defined by thepiston housing 24 and thepiston 28. Increased pressure in the tubing ID increases pressure in thespace 52 resulting in a differential pressure across thepiston 28 and accordingly movement of thepiston 28.Flow port 46 allows fluid flow between outside of thevalve 10 and inside thebody 16, when thehydraulic valve 38 is open. It is also noted that, in an embodiment, aflow path 48 may be defined between ascreen 50 and theflow port 46. It is to be understood however that thevalve 10 is not limited to use with a screen. - Turning now to operation of the
valve 10, and toFIGS. 2A-5 in sequence, thevalve 10 is runnable into aborehole 54 on astring 56 to a desired location. In some embodiments this will be as a part of a lower completion after deployment of which, other borehole operations might occur. One of the benefits of the arrangement disclosed herein is that such other borehole operations may be conducted after installation ofvalve 10 without concern for inadvertent hydraulic actuation of thevalve 10 since themechanical component 12 prevents such hydraulic actuation until specifically enabled by repositioning of themechanical component 12. It is noted in passing that prior art systems required additional equipment and runs to render lower completions installed for similar purpose but of different types than that disclosed herein safe for other borehole operations. These of course significantly increase cost and require additional rig time. - Valve 10 in
FIG. 2A is in the run position with thehydraulic valve 38 closed and locked and themechanical component 12 locked.FIG. 3 provides a larger view and hence should be referred to simultaneously withFIG. 2A in the following discussion. The distinction in position or attitude ofpiston 28, and aresilient member 58 such as spring in operable communication therewith can be seen betweenFIG. 2A andFIG. 2B . This is due to an increase hydraulic pressure in the tubing ID causing a differential pressure acrosspiston 28 as discussed above. It will be noted that becausemandrel 22 is in contact withvalve stem 36, during this pressure event, two things occur. Thevalve stem 36 and accordingly thehydraulic valve 38 are immobile and because themandrel 22 is in contact with thevalve stem 36, theinterconnection feature 34 cannot engage thevalve stem 36 and so movement of thepiston 28 will not result in any impetus to thehydraulic valve 38 to move. This is illustrative of the pressure insensitivity ofvalve 10 while themechanical component 12 is in its locked position. When themechanical component 12 is in the unlocked position, this same activity pursuant to a pressure event, will result in thehydraulic valve 38 moving to an open position (addressed further below). - At a time when it is desired to make the
valve 10 responsive to hydraulic pressure actuation, a shifting tool is run in the hole to shift themechanical component 12 to an unlocked position. InFIG. 2A , thecomponent 12 is illustrated as asleeve 18. The shift in position ofsleeve 18 can be seen in HG 4A along with a shift in the position ofextension 20 andmandrel 22. Thevalve 10 is now unlocked and upon a pressure event thehydraulic component 14 will react resulting in opening of thehydraulic valve 38. It is to be understood that the terms “responsive” and “unresponsive” as used herein relate to thehydraulic valve 38 responding to a pressure event or thehydraulic valve 38 not responding to the pressure event. Thehydraulic component 14 as a whole in the embodiment illustrated will always respond to a pressure event in that thepiston 28 will move.FIG. 4B illustrates a pressure event in the unlocked condition. It will be appreciated that thepiston 28 is moved as it was inFIG. 2B but that this time, themandrel 22 is not against thevalve stem 36. Because of this change in condition, theinterlock feature 34, which may be a collet or similar, is allowed to snap closed aboutvalve stem 36. Notice thatresilient member 58 is compressed inFIG. 4B where is it relaxed inFIG. 4A . This compression ofspring 58 means that upon reduction of the pressure event applied to cause theinterlock feature 34 to engage thevalve stem 36, thespring 58 will push thepiston 28 back toward thespace 52 takingvalve stein 36 and therebyhydraulic valve 38 with it such that thevalve 10 is in the position illustrated inFIG. 5 . Theflow port 46 is open in this position allowing fluid flow between the ID of thebody 16 and the volume outside of thebody 16. - The
valve 10 is resettable by shifting themechanical component 12 back to the position shown inFIG. 2A . It is also noted that the mechanical component may include aprofile 60 that is selected to each valve or is of the same shape for each valve with the purpose of allowing for the shifting tool (not shown) to engage the mechanical component for shifting its position from locked to unlocked or vice versa. - In another embodiment of a hydraulic component there is an indexing configuration allowing for multiple pressure cycles following unlocking of the mechanical component before the hydraulic component will complete its task of opening the hydraulic valve. This configuration allows for pressure testing of borehole tools prior to opening the hydraulic valve. Referring to
FIGS. 6-8 , anindexing configuration 70, such as a J-slot, is disposed in operable communication with thepiston 28. In the illustrated embodiment and in comparison to the foregoing embodiment, one will appreciate that theconfiguration 70 simply replaced a portion of the longitudinal extent ofpiston 28. It is to be understood that length is relative and no limitation is intended hereby. Theconfiguration 70 interacts with apin 72 extending from the piston housing. Upon pressure events in the tubing as in the foregoing embodiment, thepiston 28 is moved leftwardly in the drawing (seeFIG. 7 ) causing theconfiguration 70 to cycle on thepin 72. This motion will continue daring subsequent pressure and pressure relief events until theconfiguration 70 reaches a position where the pin is allowed to move further allowing engagement of theinterlock feature 34 with the valve stem (seeFIG. 8 ). The number of pressure cycles for testing purposes prior to opening of the hydraulic valve may be selected at the time of assembly of the tool either by selecting aconfiguration 70 having the appropriate number of cycles or by positioning ageneric configuration 70 so that a selected number of cycles remain before actuation is possible. - The
valve 10 may be used on its own, with a screen, in a multizone configuration as inFIG. 9 , etc. - In one iteration of a borehole system a lower completion comprises one or more of the
valves 10. These are run in the hole and deployed there. They will have no effect until a shifting tool is run to unlock the mechanical components, normally carried out after or simultaneously with the deployment of an upper completion. Thereafter, one or more of thevalves 10 may be opened pursuant to a pressure event caused by pressuring up on the tubing string that represents the upper and lower completions. - Set forth below are some embodiments of the foregoing disclosure:
- A mechanically lockable and unlockable hydraulically activated valve including a mechanical component having a locked position and an unlocked position, a hydraulic component in operational communication with the mechanical component, the hydraulic component including a portion that is unresponsive to pressure events with the mechanical component in the locked position and responsive to pressure events with the mechanical component in the unlocked position.
