Abstract
A jet pump assembly and method for removing fluid from a well bore extending into a formation is disclosed. The jet pump assembly includes a jet pump interposed between a tubing string and a packer. The jet pump includes a body having an outer surface, a lower tubular end, an upper tubular end connected to a lower end of the tubing string, and a central axial bore intersecting the upper tubular end at a discharge end and extending partially through the pump body toward the lower tubular end. The pump body further has a plurality of radial inlet ports intersecting the central axial bore and a plurality of production ports extending from the lower tubular end to the upper tubular end in a non-intersecting relation to the injection ports. The central axial bore is shaped to provide a non-restricted flow path from the point the injection ports intersect the central axial bore to the discharge end of the central axial bore.
