Title: Method and apparatus for removing excess water from subterranean wells

Abstract

A method is described of removing water from a subterranean hydrocarbon formation comprising the steps of: drilling a well through the hydrocarbon producing formation and downwardly to a water absorbing formation; running a casing string into the well through the hydrocarbon formation and downwardly to the water absorbing formation; perforating the casing at a plurality of vertically spaced locations adjacent the hydrocarbon producing formation; assembling a tool string including from the bottom up a tubular portion including a one-way flow valve, a tubing inlet port, a first blanking plug, a lower packer sealingly secured to the tubular portion; a fluid pump having a casing-tubing annulus intake and an output port, a pump output conduit communicating between the pump output and the tubing inlet port, a second blanking plug, a perforated nipple, and an upper packer spaced above the second blanking plug and above the casing perforations; running the assembled tool string into the well to position the lower packer below the casing perforations and the upper packer above the casing perforations; setting the packers; and operating the pump to force fluid in the casing annulus below the casing perforations downwardly through the lower packer and the one-way flow valve tomore » the water absorbing formation.« less
