Abstract
A fluid loss control valve and packer assembly including a fluid loss control valve, a packer disposed adjacent the fluid loss control valve, a hydraulic opening module operably connected to the valve, and a port associated with the hydraulic opening module and positioned to be exposed to annulus pressure during use. A method for operating a fluid loss control valve in an assembly.
Description
- In the subsurface resource recovery industry, and particularly in borehole based recovery operations, fluid loss control valves are employed with hydraulic operating modules. These are commonly operated to prevent fluid loss to the formation after a running tool is removed from the borehole. Such valves are generally closed by a shifting tool that is a part of the running tool that engages a profile as the running tool is withdrawn from the borehole thereby dragging the profile with the shifting tool resulting in the closure of the valve. Such valves may again be opened using pressure cycling in the tubing of the system. The systems used today are generally long and require large power springs to ensure cycling occurs properly to actuate the valve to the open position when it is desired to open the valve.
- In an ever tightening economic climate related to hydrocarbon recovery, the art would well receive enhancements that increase efficiency and/or reduce cost.
- A fluid loss control valve and packer assembly including a fluid loss control valve, a packer disposed adjacent the fluid loss control valve, a hydraulic opening module operably connected to the valve, and a port associated with the hydraulic opening module and positioned to be exposed to annulus pressure during use.
- A method for operating a fluid loss control valve in an assembly as in any prior embodiment including moving a piston where differential pressure across the piston is defined by a tubing pressure on one side and annulus pressure uphole of the packer on the other side, counting piston movement cycles with the module, and cycling the valve when a selected number of piston cycles is met.

FIG. 7 is a schematic view illustrating yet another port position. - A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
- Referring to
FIG. 1 , a run-in position of the fluid loss control valve andpacker assembly 10 disclosed herein is illustrated. Components included are avalve 12, which may be a ball valve in some embodiments; a packer 14 comprising a body 16, anelement 18 andslips 20; alinkage 22 andprofile 24 configured to physically move thevalve 12 to a closed position from an open position; ahydraulic opening module 26, having apiston arrangement 28, acounter 30 and in some embodiments apower spring 32, and a seal bore 34. - It is to be appreciated that the
valve 12 andhydraulic opening module 26 are similar to those available commercially from Baker Hughes, Houston, Tex. under product family number H48788 and accordingly substantial detail regarding the same is unnecessary in this document. - Attention is directed to the packer 14 and its position concentric with the
sump space 13 of thevalve 12. In prior art assemblies generally similar to the function hereof, one will anticipate to see an extended sump in the location where the packer 14 is located herein. The sump is known to be necessary to allow for tools to be withdrawn from thevalve 12 prior to closing the same with theprofile 24 andlinkage 22. This effectively dead space in prior art assemblies is costly, makes the overall assembly significantly longer and more difficult to manage and increases the cost of the assembly. The inventors hereof have discovered that a packer may be positioned in this location without detrimental effect on the operation of thevalve 12 and hence have effected a reduction in the length of the assembly while also reducing the cost thereof. - It is further presented herein that the
hydraulic opening module 26 be provided with aport 36 exposed to annulus pressure. The port is to be exposed to annulus pressure uphole of the packer 14. Theport 36 provides an opportunity to use annulus pressure to cycle the hydraulic opening module, if desired. In addition, the positioning of theport 36 is advantageous over the prior art systems because by positioning the port with exposure to an annular space that is hydraulically connected to surface, i.e. above the packer 14, the pressure in the annulus can at least be known and ideally can also be controlled. That the annulus pressure at theport 36 is known ensures that needed differential pressure from the tubing in order to cycle thehydraulic opening module 26 can be properly achieved and ensure that cycling occurs. This is far superior to prior art assemblies where differential pressure across the hydraulic opening module would be pressure below a prior art packer. While pressure in the location below the packer and valve of such prior art assemblies is known as the running tool is withdrawn from the borehole, after the valve is closed, the pressure in that area may change due to leakoff to the formation or fluid pressure migration toward the borehole causing the pressure in that location to rise. In either case, the pressure differential required to cycle may need to be significantly different than anticipated from the pressure measurements taken by pressure transducers or calculated hydrostatic pressure. Many prior art configurations of the module then would use large power springs. These add expense to the assembly and hence are undesirable. - In the present assembly, since the annulus pressure is known and in some cases adjustable, the differential is more closely controllable and the
power spring 32 may be downsized or even eliminated in some embodiments. Each of these conditions reduces costs of the assembly and is therefore beneficial to the art. - It is further to be understood that the
hydraulic opening module 26 may be located above the packer 14, at the packer 14 or below the packer 14 provided that theport 36 is always exposed to annulus pressure above the packer 14. It is also to be understood that thevalve 12 may be above, at or below the packer 14 as desired, again with the caveat that the assembly must provide for annulus pressure above the packer 14 to be available to themodule 26. This may be accomplished in some embodiments, referring toFIGS. 5-7 , with anannular flow space 40 within theassembly 10; with acontrol line 42 extending through theassembly 10; or simply an opening through a wall of the assembly 10 (illustrated simply as theport 36 itself) depending upon where the piston 28 (for j-slot/ratchet/etc. cycling) is located relative to the packer 14. Also note that because of the configuration ofFIGS. 5-7 , theport 36 can be positioned a long distance uphole of the packer 14. This may be of value where debris is an issue since if theport 36 is close to thevalve 12 and debris occludes theport 36, difficulty may be experienced in cycling thecounter 30. Placing theport 36 higher in theborehole 44 can be beneficial in avoiding interference from debris. - In operation, referring to
FIGS. 1-4 , theassembly 10 is run downhole and the packer 14 is set against aborehole 44. Thevalve 12 is open for the passage of the running tool (not shown). Borehole activities are undertaken after which the running tool is withdrawn and in so doing, the 12 is closed through the action of theprofile 24 engaging a shifting tool on the running tool (not shown) and pulling thelinkage 22. Theassembly 10 is hence in the condition shown inFIG. 2 . Later when appropriate, aproduction string 46 is run havingproduction seals 50 thereon that land in seal bore 34 as shown inFIG. 3 . Once theproduction seals 50 are present, there is pressure isolation between the tubing of theproduction string 46 and theannulus 52. Pressure cycling may be undertaken at any time utilizing a differential between the tubing pressure within theproduction string 46 and annulus pressure in theannulus 52. Either the tubing may be pressured up upon or the annulus may be pressured up upon as desired to create the differential pressure and move thepiston 28 to cycle thecounter 30. It should be noted that because of the exposure of theport 36 to annulus pressure above the packer 14, this assembly allows for annulus activation of themodule 26 when heretofore such actuation was not possible or even contemplated. The differential pressure created either by raising tubing pressure and/or raising annulus pressure cycles to the counter 30 a number of times that is generally a preset value input by the operator. When the desired number of cycles has been achieved, themodule 26 will open thevalve 12 thereby enabling production throughvalve 12 as shown inFIG. 4 . It is noted that thehydraulic opening module 26 may be a resectable type or a non-resettable type as selected during manufacture. - Set forth below are some embodiments of the foregoing disclosure:
