AI summary

A jet pump system and method facilitate the production of a subterranean fluid. The jet pump system comprises a jet pump, a surface pump, a surface pump gauge, and a pump driver coupled to the surface pump to change a drive frequency of the pump driver based on production parameters and pumping parameters of the surface pump (drive frequency (FR) of the surface pump and the power fluid parameters) whereby the surface pump is selectively varied to optimize production. The jet pump method involves deploying the jet pump into the wellbore; pumping power fluid through the jet pump using the surface pump; measuring the pumping parameters; generating the production parameters of the subterranean fluid produced (production rate (QP) of the subterranean fluid); and optimizing the producing by changing the drive frequency (FR) based on the measured power fluid parameters and the generated production parameters.
