Abstract
A single conduit lift pump is disclosed that only requires a single fluid conduit for both the driving fluid and the pumping action of the pump in a well bore. Fluid pressure communicated to the pump by the single fluid conduit drives the pump to load a resilient member. The fluid pressure is cycled off to allowing the lift of fluid by action of the resilient member upon the single fluid conduit. The single fluid conduit makes this pump suitable for downhole operations for the oil and gas production industries in wells that have substantial water cut that inhibits the production of gas.
