Abstract
A through-accessible reversible operation jet pump for attachment to a tubing string includes a pump housing having a pump housing interior and a jet pump assembly retrievably disposed in the pump housing interior. The jet pump assembly includes a carrier, a carrier nozzle in the carrier and at least one carrier opening in the carrier and establishing communication between the carrier nozzle and the pump housing interior. The jet pump assembly is adapted to be selectively removed from the pump housing interior through the tubing string as the pump housing remains attached to the tubing string. The carrier or the jet pump assembly is selectively positional in a first orientation in the pump housing interior to facilitate operation of the jet pump in a first fluid flow direction operational mode. The carrier of the jet pump assembly is selectively positional in a second orientation in the pump housing interior to facilitate operation of the jet pump in a second fluid flow direction operational mode opposite the first fluid flow direction operational mode.
