Downhole Hydraulic Motor

Abstract

This relates to an improved downhole hydraulic motor powered by a surface pump unit. The improved submersible hydraulic motor can comprise an engine. The hydraulically driven engine can be operable in a downhole environment. The engine can comprise an inlet port and an outlet port. The inlet port can be operable to receive a fluid from a surface pump unit, while the outlet port can be operable to emit said fluid from said engine.
