Abstract
Description
- The present invention relates to subterranean operations and, more particularly, to a method and system for opening and closing a subsurface valve used in conjunction with such operations.
- Hydrocarbons, such as oil and gas, are commonly obtained from subterranean formations that may be located onshore or offshore. The development of subterranean operations and the processes involved in removing hydrocarbons from a subterranean formation are complex. Typically, subterranean operations involve a number of different steps such as, for example, drilling a wellbore at a desired well site, treating the wellbore to optimize production of hydrocarbons, and performing the necessary steps to produce and process the hydrocarbons from the subterranean formation.
- When performing subterranean operations, it may be desirable to close off a well in the event of an uncontrolled condition that may damage property, injure personnel or cause pollution. One of the mechanisms used to close off a well is a Surface Controlled Subsurface Safety Valve (“SCSSV”). An SCSSV typically includes a flapper. The flapper is a closure member that may be pivotally mounted such that it is rotatable between a first “open” position and a second “closed” position. When in the closed position, the flapper may close off the well. However, SCSSVs are often made with many small, specialized parts that are costly to implement and/or replace.
- It would be advantageous to have a fail-safe SCSSV that may be installed without the use of small, specialized parts. This would reduce costs and increase efficiency.

- Referring now to
FIG. 1 , oil well drilling equipment used in an illustrative drilling and completion environment is shown. A cross-sectional view of awellbore 116 that has been drilled withcasing 128 andtubing 126 in accordance with certain embodiments of the present disclosure is denoted generally withreference numeral 100. Adrilling platform 102 supports aderrick 104 having atraveling block 106 for raising and lowering a drill string (not shown), wireline, slickline, or coiled tubing. Anannulus 132 is formed between thecasing 128 and theformation 130.Cement 118 is pumped down thewellbore 116, e.g., through the interior of thecasing 128 and up through theannulus 132 where it sets and holds thecasing 128 in place. Thecement 118 may be directed downhole using a cement pumping unit (not shown) or other types of rig pumping equipment (not shown), as appropriate. Thecasing 128 andtubing 126 may be concentric tubes inside thewellbore 116. An SCSSV 120 may be installed in thewellbore 116 withtubing 126 coupled to each side as shown inFIG. 1 . In such embodiments, the SCSSV 120 would be semi-permanently installed in thewellbore 116. In order to remove theSCSSV 120, the entire string oftubing 126 may be removed from thewellbore 116. In other embodiments, not shown inFIG. 1 , the SCSSV 120 may be installed in thewellbore 116 on wireline, coiled tubing, or some other semi-flexible work string. In such embodiments, the SCSSV 120 may be installed in a profile that is communicatively coupled to a control line (not shown) that runs to the surface of thewellbore 116. - Turning now to
FIG. 2A , an SCSSV in accordance with an illustrative embodiment of the present disclosure is denoted generally withreference numeral 200. In the embodiment shown inFIG. 2A , theflapper 206 is shown in a first open position. The SCSSV 200 includes arod piston 202 disposed within ahousing 204. For illustrative purposes, SCSSV 200 ofFIG. 2A may have a first distal end 202A, a middle portion 202B and a second distal end 202C. Therod piston 202 may be coupled to atubing member 216. Aseat 214 in a valve housing (not shown) may surround thetubing member 216. Aflapper 206 may be pivotally mounted to afirst connector beam 210 such that theflapper 206 is rotatable between an open position and a closed position. In the embodiment shown inFIG. 2A , theflapper 206 is shown in an open position. - In operation of the SCSSV 200, a
control line 220 may be coupled to therod piston 202. The control line may deliver pressure to therod piston 202 from the surface or from a desirable subsurface location. Pressure from therod piston 202 may hold thetubing member 216 in place and in engagement with theflapper 206. Thus, when theflapper 206 is in the open position, it may be held in contact with thetubing member 216. Theflapper 206 is shown in further detail inFIGS. 2A-2B andFIGS. 3A-3B . If it is desirable to close theflapper 206, the pressure applied to therod piston 202 may be reduced or eliminated. In some embodiments, pressure may be applied to thecontrol line 220 which communicates with therod piston 202 at surface or from a desirable subsurface location prior to deployment of theSCSSV 200. Pressure may be maintained throughout deployment to verify integrity of the control system andSCSSV 200. Thus, in order to close theflapper 206, the operator may alter the pressure applied to the control line at the surface. In other embodiments, theflapper 206 may be mechanically propped open during installation. Thus, in order to close theflapper 206 in those embodiments, the operator may retract the mechanical prop to the surface. Either of these scenarios may allow the spring 202B to partially decompress, allowing thetubing member 216 to move uphole. Thetubing member 216 thus may be disengaged from theflapper 206. This in turn may allow awave spring 318 to partially decompress, causing theflapper 206 to close. Thus, thewave spring 318 may rotate the flapper between its open and closed positions. This is shown in further detail inFIGS. 2B, 3A, and 3B . Anexemplary wave spring 500 is shown in further detail inFIG. 5 . - The
wave spring 318 may be made from flat wire, and may include waves that are in contact with each other, as shown in further detail by theexemplary wave spring 500 inFIG. 5 . The waves may deflect during compression. A coiled spring, by contrast, may be manufactured from round or square wire that is coiled into a desired shape. As a coiled spring is compressed, the coils get closer together. There are several advantages associated with using thewave spring 318 rather than a coiled spring in an SCSSV application. First, the shorter size of thewave spring 318 compared to a coiled spring that is able to deliver the same operating load makes thewave spring 318 more desirable because of the limited space available in the SCSSV and in thewellbore 116. In other words, thewave spring 318 may be able to provide the same operating loads as a coiled spring but using a shorter design. Thus, thewave spring 318 may provide a greater operating load than a coiled spring of the same length and diameter. Second, use of awave spring 318 allows the motion of theflapper 206 to be more controlled and adjustable as compared to using a coiled spring. Thewave spring 318 may be of any length, so that the speed and motion of theflapper 206 closure may be controlled as desired. Third, an SCSSV that includes awave spring 318 as provided in the present disclosure requires fewer components than previous SCSSVs that included a coiled spring. Therefore, the SCSSV is less expensive to replace and manufacture. - Turning now to
FIG. 2B , theflapper 206 ofFIG. 2A is shown in the closed position. When theflapper 206 is in the closed position, it may engage with the seat (not shown inFIG. 2B ), creating a seal in the wellbore. - Turning now to
FIGS. 3A and 3B , a flapper valve assembly in accordance with an illustrative embodiment of the present disclosure is denoted generally withreference numeral 300.FIG. 3B depicts a cross-sectional view. In the embodiment shown inFIGS. 3A and 3B , theflapper 206 is shown in the open position. In certain illustrative embodiments, acollapsible member 308 may be coupled to theflapper 206. Theconnector beam 210 may be coupled to thecollapsible member 308. Thecollapsible member 308 is shown in a collapsed position. Awave spring housing 312 may be coupled to theconnector beam 210. Thewave spring housing 312 includes awave spring 318, which may be in an at least partially compressed position when theflapper 206 is in the open position. In other words, thewave spring housing 312 may surround or contain thewave spring 318. Thewave spring 318 may be in a compressed position, and therefore may exert force on theconnector beam 210 and thecollapsible member 308. However, thetubing member 216 may be engaged with theflapper 206 and may prevent it from closing. Thus, thetubing member 216 is engaged with theflapper 206 when theflapper 206 is in the open position, as shown inFIGS. 3A and 3B . - In operation of the
system 300, when a well operator desires to shut off the well, pressure may be removed from therod piston 202 at the surface. Thus, thetubing member 216 may move uphole, allowing thetubing member 216 to disengage from theflapper 206 and thus removing support from theflapper 206. This may allow thewave spring 318 to partially decompress and theflapper 206 to close, engaging with theseat 214. - Turning now to
FIGS. 4A and 4B , a flapper valve assembly in accordance with another illustrative embodiment of the present disclosure is denoted generally withreference numeral 400.FIG. 4B depicts a cross-sectional view. In the embodiment shown inFIGS. 4A and 4B , pressure has been removed from therod piston 202, allowing thetubing member 216 to disengage from theflapper 206. Thus, the force exerted from thewave spring 318 on theconnector beam 210 and thecollapsible member 308 may allow thecollapsible member 308 to extend, pushing theflapper 206 into a closed position. Thus, inFIGS. 4A and 4B , thewave spring 318 is shown in a partially decompressed position, thecollapsible member 308 is shown in an extended position, and theflapper 206 is shown in a closed position such that it is engaged with theseat 214. - In existing SCSSVs, debris may prevent the flapper closure mechanism from functioning properly and may have prevented
flapper 206 from engaging with theseat 214 and closing completely. In contrast, in the improved design disclosed herein, thewave spring housing 312 andwave spring 318 may be located uphole of theflapper 206. As a result, unlike typical prior art SCSSV designs, the flapper closure mechanism disclosed herein is located outside of the direct debris path of thewellbore 116 because thewave spring housing 312 andwave spring 318 may be located uphole of theflapper 206. - As would be appreciated by those of ordinary skill in the art, the methods and systems disclosed herein may be applicable to more than just SCSSVs. Accordingly, any reference to a “tubing member” is made for illustrative purposes only and is intended to generically refer to a part of a tool that is actuated by a rod piston of a control system.
- The present invention is therefore well-adapted to carry out the objects and attain the ends mentioned, as well as those that are inherent therein. While the disclosure has been depicted, described and is defined by references to examples of the disclosure, such a reference does not imply a limitation on the disclosure, and no such limitation is to be inferred. The disclosure is capable of considerable modification, alteration and equivalents in form and function, as will occur to those ordinarily skilled in the art having the benefit of this disclosure. The depicted and described examples are not exhaustive of the disclosure. Consequently, the disclosure is intended to be limited only by the spirit and scope of the appended claims, giving full cognizance to equivalents in all respects.
