Abstract:
An electric submersible hydraulic lift pump system is used for removing fluid from a well. The hydraulic lift pump system includes a source of fluid, a tubing string extending from the surface and in fluid communication with the source of fluid, a first pump interposed in the tubing string so the first pump is positioned below the surface and operably arranged to draw fluid from the tubing string upstream of the first pump and to discharge the fluid into the tubing string downstream of the first pump as a power fluid, and a second pump interposed in the tubing string and operably arranged to receive the power fluid from the first pump and be combined with a production fluid to form a return fluid to be discharged into the annulus.

Claim (Index 15):
A method of removing fluid from a well extending downwardly from a surface, the method comprising:\n extending a tubing string from the surface with the tubing string being in fluid communication with a fluid source at the surface, a first pump having an inlet and an outlet interposed in the tubing string so the first pump is positioned below the surface with the inlet positioned upstream of the outlet relative to the fluid source and a second pump having a power fluid inlet, a well fluid inlet, and an outlet interposed in the tubing string so the second pump is in fluid communication with the first pump and the fluid in the well; passing fluid from the fluid source into the tubing string upstream of the first pump; and activating the first pump to draw fluid from the tubing string upstream of the first pump and to discharge the fluid from the outlet of the first pump into the tubing string downstream of the first pump as a power fluid so the power fluid is passed through the power fluid inlet of the second pump so the power fluid causes fluid to be drawn from downhole of the second pump, combined with the power fluid to form a return fluid, and the return fluid to be discharged through the outlet and into the well.
