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 1):
A hydraulic lift pump system for removing fluid from a well extending downwardly from a surface, the hydraulic lift pump system comprising:\n a source of fluid positioned at the surface; a tubing string extending from the surface and being in fluid communication with the source of fluid; a first pump having an inlet and an outlet, the first pump 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 source of fluid so the first pump is 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 outlet of the first pump as a power fluid; and a second pump having a power fluid inlet, a well fluid inlet, and an outlet, the second pump interposed in the tubing string so the second pump is in fluid communication with the first pump and the fluid in the well and operably arranged to receive the power fluid from the first pump through the power fluid inlet so the power fluid causes the 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.
