<p>A method to produce formation fluid from an oil or gas well. The methods employs a jet pump and a spoolable multi-string tubing system. The jet pump is adapted to produce formation fluid, which may be produced in combination with power fluid. The multi-string tubing system consists of two or more tubing conduits, allowing surface pump equipment to deliver power fluid to the jet pump down a supply tubing string, while return fluid is returned up a return tubing string. Other downhole functions can be provided with the inclusion of additional features on the jet pump and additional conduits or conductors in the multi-string tubing system. Preferred embodiments provide additional functionality by inclusion of a jetting sub, sensing elements, or a back-pressure valve to the jet pump, and auxiliary tubing strings or communication members to the spoolable multi-string tubing system.</p> |
