Abstract
A system and method is provided for artificially lifting fluids from a formation. The system utilizes a production control unit having a jet pump assembly and valving to both lift the desired fluids and to provide well control.
Claims18
A method of controlling fluid flow in a wellbore, comprising:
- delivering a jet pump and a safety valve to a wellbore location in a single trip downhole, wherein delivering comprises delivering the jet pump and the safety valve via a slickline;
- and
- controlling the safety valve to enable selective flow of fluid upwardly through the wellbore via the jet pump.
A method of controlling fluid flow in a wellbore comprising:
- delivering a jet pump and a safety valve to a wellbore location in a single trip downhole, wherein delivering comprises delivering the jet pump and the safety valve via a wireline;
- and
- controlling the safety valve to enable selective flow of fluid upwardly through the wellbore via the jet pump.
A method of controlling fluid flow in a wellbore, comprising:
- delivering a jet pump and a safety valve to a wellbore location in a single trip downhole;
- and
- controlling the safety valve to enable selective flow of fluid upwardly through the wellbore via the jet pump;
- and
- operating the jet pump by pumping power fluid down through a well tubing, through the jet pump and up through an annulus surrounding the well tubing.
A method of controlling fluid flow in a wellbore, comprising:
- delivering a jet pump and a safety valve to a wellbore location in a single trip downhole;
- and
- controlling the safety valve to enable selective flow of fluid upwardly through the wellbore via the jet pump, wherein controlling comprises opening the safety valve via pressure of power fluid applied to operate the jet pump.
A method of controlling fluid flow in a wellbore, comprising:
- delivering a jet pump and a safety valve to a wellbore location in a single trip downhole;
- and
- controlling the safety valve to enable selective flow of fluid upwardly through the wellbore via the jet pump;
- and
- deploying a sliding sleeve at the wellbore location to receive the safety valve.
A method of utilizing a wellbore completion having a downhole receptacle above a packer, comprising:
- moving a production control unit, having a jet pump and a safety valve, into engagement with the downhole receptacle;
- and
- hydraulically coupling the jet pump and the safety valve to enable opening of the safety valve via the pressure of power fluid directed through the jet pump.
A system for controlling fluid flow in a wellbore, comprising:
- means for utilizing a power fluid to produce a wellbore fluid;
- means for selectively preventing all upward flow of fluid in the wellbore;
- and
- means for simultaneously delivering the means for utilizing and the means for selectively preventing to a desired wellbore position, wherein the means for simultaneously delivering comprises a slickline.
