A pump includes a drive chamber with a drive piston and a production chamber with a production piston. The drive piston is coupled to the production piston. The pump further includes a passage in fluidic communication with the drive piston and a port fluidically coupling the passage with the production chamber. In operation, a first pressure is applied to fluid in the passage, thereby moving the drive piston. Then a second higher pressure is applied to fluid in the passage, thereby opening a valve associated with the port. In an example operation, fluid flows from the passage into the production chamber, and flushes gas out of the production chamber, thereby alleviating gas-locking. In another example operation, fluid including a treatment chemical flows from the passage into the production chamber. A surface equipment package includes a controller configured to monitor and control operation of the pump.

Method and system for producing well fluids

A release tool for connecting a workstring to a toolstring. The release tool will be used for contingency if the toolstring gets stuck downhole and hopefully rarely would be actuated. In the present disclosure, the release tool is not broken or destroyed, but is simply disconnected into two parts using the propellent of a low explosive combustion element. This element produces gasses that drive the disconnecting process. The gasses are directed to press a tubular piston to translate from a first position where a wedging portion of the tubular piston is inside a lock ring bracing the lock ring in a locking configuration to a second position where the wedging portion is out of contact with the lock ring. The lock ring is then able to slip free from one or more locking grooves releasing the upper portion of the release tool from the lower.

A toolstring for plugging and perforating a wellbore includes a perforating gun extending between an uphole end and a downhole end longitudinally opposed to the uphole end, a plugging assembly extending between an uphole end and a downhole end longitudinally opposed to the uphole end of the plugging assembly, the plug assembly including a setting tool physically attached directly to the perforating gun, the setting tool including an elongate housing extending between an uphole end and a downhole end opposite the uphole end of the housing, an open passageway extending from the uphole end to the downhole end of the housing, and wherein the setting tool further includes an elongate mandrel positioned in the open passageway and having an uphole end and a downhole end opposite the uphole end of the mandrel, and a combustion chamber located within the elongate housing for receiving an energetic charge.

Plugging assemblies for plugging cased wellbores

A method of producing fluid from a wellbore includes operating a pump located proximate to a zone of fluid influx in the wellbore to draw a fluid from a reservoir into the wellbore at the zone of fluid influx. A first section of a tubing string is coupled to, and extends above, the pump, and a second section of the tubing string is coupled to, and extends below, the pump. A packer seals a first annular space around the first section of the tubing string. The method further includes operating the pump to move the fluid from the second section of the tubing string and into the first section of the tubing string.

Downhole pump and method for producing well fluids

A multiplier sleeve has a releasable seat coupled to a dog within the slidable sleeve allows a single sized ball, dart, or plug to actuate several sliding sleeves. Upon actuation by properly sized ball the ball, slidable sleeve, seat, and dog move downward where the dog is no longer supported allowing the seat to move within the slidable sleeve to a point where the seat is no longer supported thereby releasing the ball. With the slidable sleeve moved downward the port or ports in the sliding sleeve is exposed. A staged port and piston assembly inserted into the ports maintain pressure within the tubular assembly to allow the ball to move through and actuate the targeted sliding sleeves.
