Abstract
Description
- Embodiments of the present invention generally relate to artificially lifting fluid from a wellbore. More particularly, embodiments of the present invention relate to artificially lifting fluid from a wellbore using a jet pump lift system.
- To obtain hydrocarbon fluids from an earth formation, a wellbore is drilled into the earth to intersect an area of interest within a formation. The wellbore may then be “completed” by inserting casing within the wellbore and setting the casing therein using cement. In the alternative, the wellbore may remain uncased (an “open hole wellbore”), or may become only partially cased. Regardless of the form of the wellbore, production tubing is typically run into the wellbore primarily to convey production fluid (e.g., hydrocarbon fluid, which may also include water) from the area of interest within the wellbore to the surface of the wellbore.
- Often, pressure within the wellbore is insufficient to cause the production fluid to naturally rise through the production tubing to the surface of the wellbore. Thus, to carry the production fluid from the area of interest within the wellbore to the surface of the wellbore, artificial lift means is sometimes necessary.
- Some artificially-lifted wells are equipped with sucker rod lifting systems. Sucker rod lifting systems generally include a surface drive mechanism, a sucker rod string, and a downhole positive displacement pump. Fluid is brought to the surface of the wellbore by pumping action of the downhole pump, as dictated by the drive mechanism attached to the rod string.
- One type of sucker rod lifting system is a rotary positive displacement pump, typically termed a progressive cavity pump (“PCP”). The progressive cavity pump lifts production fluid by a rotor disposed within a stator. The rotor rotates relative to the stator by use of a sucker rod string.
- An additional type of sucker rod lifting system is a rod lift system, with which fluid is brought to the surface of the wellbore by reciprocating pumping action of the drive mechanism attached to the rod string. Reciprocating pumping action moves a traveling valve on the positive displacement pump, loading it on the down-stroke of the rod string and lifting fluid to the surface on the up-stroke of the rod string.
- Sucker rod lifting systems include several moving mechanical components. Specifically, the rod strings of sucker rod lifting systems must be reciprocated or rotated to operate the lifting systems. In some applications, the moving parts are disadvantageous. When a subsurface safety valve is employed within the wellbore, such as within an offshore well, a sucker rod string cannot be placed through the subsurface safety valve. Additionally, moving parts are susceptible to failure or damage, potentially causing the sucker rod lifting systems to become inoperable.
- An alternative lift system involves using a jet pump. As shown in
FIG. 1 , aproduction tubing 10 having ajet pump 20 is installed in acasing 15. Thejet pump 20 includes a nozzle section, a venturi section, and inlets ports in fluid communication with the venturi section. Aported sub 22 fluidly connects the bottom of the venturi section with the annular area between thetubing 10 and thecasing 15. Production fluid flowing up thetubing 10 can flow into the venturi section via the inlet ports. - In operation, power fluid is directed down the
tubing 10 toward the nozzle section of thejet pump 20. Power fluid exiting the nozzle section is directed through the venturi section. As the power fluid passes from the nozzle section to the venturi section, production fluid is drawn into the venturi section via the inlet ports. The combined power fluid and production fluid leave the venturi section via theported sub 22 and enter the annular area, where the combined fluids flow upward to the surface. - In many of these operations, a safety valve is attached to a
landing nipple 23 disposed below thejet pump 20. The safety valve serves as a safety barrier for both thetubing 10 and thecasing 15 by blocking communication through the bore of thetubing 10. In some instances, the jet pump is installed at depths of 8,000 ft. or more. Because the safety valve is below the jet pump, the safety valve must be rated for use at these depths. The safety valves required for these depths are usually much more expensive than safety valves rated for use at shallower depths; in some instances, more than double or triple the costs. The cost associated with control lines for operating the safety valves also increase with depth. - There is, therefore a need for an improved lift system for producing hydrocarbon fluids. There is also need for a lift system that allows a safety valve to be installed above a jet pump.
- In one embodiment, a jet pump lift system for use with a tubing disposed in a casing includes a jet pump installed in the tubing; a one way valve for communicating a power fluid into the jet pump; and a safety valve configured to block fluid communication through the tubing and disposed above the jet pump.
- In another embodiment, a method of producing hydrocarbon fluids includes installing a jet pump in a production tubular; maintaining a safety valve located above the jet pump in an open position; supplying a power fluid through a one way valve and into the jet pump; urging a production fluid into the jet pump; and flowing the production fluid and the power fluid past the safety valve.
- So that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.

FIG. 2 shows an exemplary artificial lift system for producing a hydrocarbon fluid.FIG. 2A is an enlarged partial view ofFIG. 2 . Ajet pump 120 is installed in aproduction tubing 110 disposed in acasing 115. Apacker 117 blocks the annular area between thetubing 110 and thecasing 115 below thejet pump 120. - The
jet pump 120 includes atubular housing 121 having an inlet located at a lower end and an outlet located at an upper end. The outer surface of the two ends of thetubular housing 121 sealingly engages the inner surface of the bore of thetubing 110. In this respect, production fluid flowing up the bore is directed into the inlet of thehousing 121. In one embodiment, the ends may be sealed using one or more sealingmembers 111 such as o-rings and chevron seals. - An
annular chamber 118 is defined between the two sealed ends and between thetubing 110 and thehousing 121 of thejet pump 120. A oneway valve 160 is used to control fluid communication between theannular chamber 118 and theannular area 113 between thetubing 110 and thecasing 115. The oneway valve 160 is configured to allow fluid in theannular area 113 to flow into theannular chamber 118. In this respect, the oneway valve 160 prevents pressure increases, such as a blow-out condition, from being communicated into thecasing 115. An exemplary one way valve is a check valve. It is contemplated that a single or a plurality of one way valves may be used to communication fluid into theannular chamber 118. In one example, the oneway valve 160 can be located at any location between the jet pump and the power fluid source. In another example, the oneway valve 160 is located below thevalve 180, as shown inFIG. 2 . In yet another example, the oneway valve 160 is located at a depth between 6,000 ft. and 30,000 ft., such as between 8,000 ft. and 20,000 ft. In a further example, the one way valve is located at a depth between 6,000 ft. and the depth of perforation. - In one embodiment, the
jet pump 120 is installed in atubing 110 having aside pocket mandrel 114, as disclosed in U.S. Pat. No. 7,228,909, which patent is incorporated by reference, in particular,FIGS. 1, 2A, 2B, 3, and 5 , and the corresponding description. -
FIG. 3 illustrate an exemplary embodiment of a oneway valve 335 suitable for use with a side pocket of the tubing. The oneway valve 335 includes atubular body 305 having a generally longitudinalcentral bore 336 therethrough and having anupper end 301 and a lower end 302. The lower end 302 includes anoutlet port 313 for ejecting fluid from thebore 336, and theupper end 301 includes a connector for connecting the one way valve to a latching mechanism for retrieval. Thetubular body 305 includes twoinlet ports central bore 336 to the outside of the oneway valve 335.Seal assemblies inlet ports seat mechanism 340 is used to control fluid communication between theinlet ports bore 336. When the fluid outside the oneway valve 335 reaches a predetermined level, the ball will be urged away from the seat, thereby allowing fluid, such as power fluid P, to flow into thebore 336. A second ball andseat mechanism 350 is disposed in thebody 305 between the first ball andseat mechanism 340 and theoutlet port 313. The second ball andseat mechanism 350 allows fluid flow from theinlet ports outlet port 350, but does not allow fluid flow in the opposite direction. - Referring back to
FIGS. 2 and 2A , thejet pump 120 includes anozzle section 122 spaced apart from aventuri section 124. The spacedarea 125 between thenozzle section 122 and theventuri section 124 fluidly communicates with the bore ofhousing 121. This arrangement allows fluid flowing through the inlet of thehousing 121 to flow toward theventuri section 124. Aside port 126 formed in thetubular housing 121 provides fluid communication between theannular chamber 118 and the interior of thenozzle section 122. Thenozzle section 122 includes athroat 128 having an inwardly tapered portion that increases the velocity of the power fluid flowing out of thenozzle section 122. Theventuri section 124 is configured to receive power fluid from thenozzle section 122 and the production fluid. Theventuri section 124 includes an outwardlytapered portion 129 that increases the pressure of the combined fluids flowing out of theventuri section 124 while decreasing the velocity of the combined fluids. Exemplary power fluids include water, oil, hydrocarbon, and combinations thereof. - A
safety valve 180 is installed in thetubing 110 and above thejet pump 120. In one embodiment, thesafety valve 180 includes aflapper 181 movable between an open position and a closed position. Theflapper 181 is operated by aflow tube 182 controlled by a control line. As shown, theflapper 181 is maintained in the open position by theflow tube 182. To close theflapper 181, pressure is supplied through the control line to move theflow tube 182 upward, thereby freeing theflapper 181 to pivot into the bore of thetubing 110 to block fluid communication through the bore. To open theflapper 181, pressure is supplied through the control line to move theflow tube 182 downward, thereby pivoting theflapper 181 away from the bore to open fluid communication through the bore. - In operation,
production fluid 141 in thetubing 110 flows upward and enters thejet pump 120 via the inlet of thetubular housing 121.Power fluid 142 is supplied down theannular area 113 between thetubing 110 and thecasing 115 toward thejet pump 120. Thepower fluid 142 then passes through the oneway valve 160 and enters theannular chamber 118. Thepower fluid 142 flows through theside port 126 toward thethroat 128 of thenozzle section 122. As thepower fluid 142 is forced through thethroat 128, the velocity of thepower fluid 142 is increased. Thepower fluid 142 exiting thethroat 128 passes through the spacedarea 125 and enters theventuri section 124. As the power fluid passes from thenozzle section 122 to theventuri section 124,production fluid 141 in the spacedarea 125 is drawn into theventuri section 124. The combinedfluids tapered portion 129, where the velocity of the combined fluids is decreased and the pressure is increased. The combinedfluids jet pump 120 and up thetubing 110. Theflapper 181 is retained in the open position to allow the combinedfluids - As discussed, embodiments of the jet pump lift system advantageously allow the safety valve to be installed above the jet pump. Because the one way valve prevents fluid communication from the
tubing 110 intoannular area 113 with thecasing 115, the safety valve only needs to block fluid communication up thetubing 110. In one example, the safety valve is located at 3,000 ft. or above, such as between 200 ft. and 2,500 ft., between 1,000 ft. and 2,000 ft., and 2,000 ft. or above. Safety valves rated for these depths cost substantially less than safety valves rated for much lower depths, such as between 8,000 ft. and 20,000 ft. - Any directional terms used in the description above are merely illustrative, for example, the terms “upward”, “downward”, etc., and not limiting. It is understood that the production tubing described above is usable within any orientation of wellbore, including but not limited to a vertical, horizontal, directionally-drilled, or lateral wellbore.
- While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
