Abstract
An artificial lift system for a horizontal well deploys a downhole pump and flexible bladder reservoir chamber to be used with a conventional rod pump. The rod pump is used in the vertical at the top of the curve. The flexible bladder reservoir chamber is connected to the rod pump intake. The downhole pump is set in the producing formation and is connected to the reservoir chamber by tubing. The lift system uses a compressor drive system to operate the downhole pump to move fluids from the producing formation to the reservoir chamber. The reservoir chamber uses the flexible chamber bladder that is filled with well fluids by operation of the downhole pump to provide a continuous supply of well fluids to the rod pump intake. Operation of the rod pump lifts fluids from the flexible chamber bladder without regard to the operation state of the downhole pump.
