ABSTRACT:
Well pumping system that uses pressurized air as power fluid and operates simultaneously as a positive displacement pump and as a gas lift pump, to pump well fluids intermitently; and also may be used in combination with fluid actuated pumping devices to pump well fluids continuously, extracting them by suction from the pores of a geologic formation through the screen of a monitoring well, as often is required for remediation purposes in hazardous wastes projects, or soil stabilization purposes in foundation engineering projects. Solid particles in the well fluids are filtered prior to entering the pumping system. Well fluids are separated from the pressurized air by passing the well fluids-pressurized air mixture through separators upon discharge.
