A Method And A System For Determining A Jet Pump Suction Pressure

Abstract: The present invention discloses a method and a system for determining a pump suction pressure value of a jet pump in a wellbore. The method comprises receiving (302) a value for one or more parameters representing characteristics of the wellbore. A plurality of candidate pump suction pressure values are generated (304) based on the value of the one or more parameters and an iterative value of the productivity index of the wellbore. Furthermore, a plurality of values for the one or more parameters are generated (306) based on each of the plurality of candidate pump suction pressure values. The pump suction pressure value is then determined (308) by selecting at least one candidate pump suction pressure value from the plurality of candidate pump suction pressure values based on the one or more generated values of the one or more parameters matching a selection criteria, wherein the selection criteria is based on a measure of similarity between the received value of the one or more parameters and the generated value of the one or more parameters. Figure 3 is the representative figure.
