Jet pump manufactured using additive and subtractive machining techniques

A method of manufacturing a jet pump, having a venturi for delivering a power fluid to a throat located downhole thereof and a plurality of ports formed therebetween for inducing production fluid into the throat comprising:

• forming a tubular body having an uphole end for connection to a tubing string and a downhole intake end for receiving production fluid from the formation;
• forming a diffuser within the tubular body extending generally axially therein, forming an annular space between the diffuser and the body, the annular space acting as a production conduit in fluid communication with the intake end;
• continuously curving the diffuser therealong from the throat to a discharge end in the body and tapering from narrow at the throat to wider at the discharge end for optimizing a cross-sectional area of the discharge end;
• wherein the body and the diffuser are additively and subtractively formed as a monolithic structure.
