Abstract
A jet pump and method of using the jet pump for removing fluids and solids from a conduit. The jet pump is adapted for use with a spoolable multi-string tubing system. The jet pump may be deployed rapidly and is suitable for temporary installation. The method may be used to reestablish flow in watered out and sanded off wells, or to test wells. The jet pump is adapted to remove wellbore fluid, which may be removed in combination with power fluid. The spoolable multi-string tubing system includes two or more substantially parallel conduits, allowing power fluid and return fluid to flow in separate conduits. Preferred embodiments provide additional functionality by inclusion of jetting elements, sensing elements, back-pressure valves, and auxiliary tubing strings or communication members in the spoolable multi-string tubing system.
