Abstract
The present invention is directed to methods for extracting fluids from oil and gas wells. More specifically, it is directed toward methods and apparatuses to power and control down hole hydraulic devices using subterranean centrifugal pumps. This invention represents a vast improvement over current hydraulic artificial lift systems. This invention provides for safe, efficient, and increased fluid recovery of oil and gas reserves from subterranean reservoirs in all types of wells, including deviated and horizontal wells.
