A downhole pump for the extraction of oil/petroleum comprises a motive fluid conduit for the conveyance of a motive flow, and a transport conduit connected to the motive fluid conduit for the conveyance of the induced flow and motive flow to the surface. The transport pipe includes a suction inlet for intake of the induced fluid, and houses a jet pump. The transport pipe and/or motive fluid pipe are configured to produce an annular or cylindrical motive jet through the nozzle, whereby an axial induced flow is produced through the suction inlet. The downhole pump therefore comprises an annular jet pump.
