Patent ID: 8863827

Claim:
A jet pump adapted for use with a spoolable multi-string tubing system comprising two or more conduits, the conduits including a supply tubing string and a return tubing string laterally disposed with respect to one another, the conduits being substantially parallel, and the jet pump comprising: a body; a power fluid inlet in the body for connecting to the supply tubing string; a venturi nozzle and a diffuser in fluid communication with the power fluid inlet; a venturi gap between the venturi nozzle and the diffuser for creating a low pressure condition at the venturi gap when power fluid flows through the venturi nozzle and past the venturi gap; a jet pump intake in fluid communication with the venturi gap for flow of wellbore fluid into the jet pump intake when the low pressure condition is created, the wellbore fluid combining with power fluid to form return fluid at the venturi gap; a return tube in fluid communication with the diffuser for receiving the return fluid from the diffuser; a return fluid outlet in the body and in fluid communication with the return tube, for connecting to the return tubing string, the return fluid outlet laterally disposed with respect to the power fluid inlet for connecting the power fluid inlet to the supply tubing string and the return fluid outlet to the return tubing string; and a jetting sub having an uphole end and a downhole end, the jetting sub in fluid communication with the power fluid inlet for emitting jetting fluid externally to the jet pump, the jetting sub comprising a jetting nozzle proximate the downhole end for flowing jetting fluid out of and an upper flow control choke proximate the uphole end for limiting flow of fluid if the jetting nozzle washes out.
