Abstract: The invention is directed to a hydraulic actuated pump system which lifts production fluids and re-circulating hydraulic fluid from a petroleum well. Additives may be added to the hydraulic fluid to apply direct chemical treatment to the production formation. A sonic stimulator may be included to stimulate and produce the same liquids from the horizontal section of the well.

Abstract: A method of stimulating or cleaning a fracture port and the proximate well bore area, includes the steps of inserting a downhole assembly on coiled tubing into a production tubing string comprising a fracture port. The downhole assembly includes a fluid pulse generator and jetting tool which is positioned adjacent the fracture port, and fluid is pumped through the tool to create fluid pressure pulses and jet streams of fluid. The method and apparatus does not require isolating the fracture port to be cleaned with packers or seals.

Abstract: A downhole positive displacement motor converts hydraulic fluid pressure into rotational torque. The motor includes a non-helical rotor and stator, and upper and lower valve assemblies each comprising cylindrical rotating and stationary elements which define longitudinal passages. The timing of alignment of the passages creates pressure in power pockets in the stator, rotating the rotor. The rotational torque can be used in any application that may require mechanical force to operate or drive a mechanism created for oil, gas, or water production in a down hole application.

Abstract: A downhole pulse stimulation tool for use within a production or injection string including a tubing string, a rotating or reciprocating rod string and a downhole pump. The tool is formed by a resonance chamber defined by a cylindrical outer tubular member connected to the tubing string and having pulse emitting openings, a pulse generator rotatably disposed within the resonance chamber having longitudinal channels and defining pulse generating openings, wherein the pulse generating openings periodically align with the pulse emitting openings as the pulse generator rotates or reciprocates within the resonance chamber.
