May 14, ALRDC Seminar for New or Novel Artificial Lift Technologies, Houston, Texas 2 General Background Hydraulic Piston Pump High pressure fluid is used to drive a piston up and down. Fluid is controlled by an Engine Valve Assembly (EVA) that redirects the power fluid to drive the engine piston. Pump piston is used to pull in formation fluid and push up to surface.

Current Piston Pump Design Hydraulic Piston Pumps stroke 70 – 80 SPM (Strokes Per Minute). –Lower limit of 20 SPM without stalling. –At 20 SPM the production range of a piston pump is BLPD. Stroke length is only 12”. Pump Piston rings susceptible to wear from abrasives in formation fluid. Many moving parts. Time and costly repairs require experience.

May 14, ALRDC Seminar for New or Novel Artificial Lift Technologies, Houston, Texas 4 New Piston Pump Design Can stroke as low as 5-10 SPM. –Reduces wear and fatigue. –Can operate at lower production rates. Minimum 10 BLPD 24” stroke length. Pump Piston can be customized for well. –2 Parts change the P/E ratio and production capabilities. Less parts to repair means more economical.
