Oil well completion with high submergence jet pump
an oil well completion comprising a well bore drilled from the surface through and below an oil producing formation to provide an extension below the producing formation, a jet pump in the extension below and in communication with the producing formation, means for conducting power fluid under pressure downwardly in the well bore from the surface to the jet pump, and means for conducting spent power fluid, and fluid from said producing formation discharged by said jet pump, upwardly in the well bore from the jet pump to the surface. The purpose of locating the jet pump in a downward extension of the well bore below the producing formation is to provide sufficient submergence of the jet pump to avoid cavitation, without curtailing the flow of fluid from the producing formation into the well bore.
