Abstract: The invention provides apparatus for producing well fluids from an oil bearing formation penetrated by a well. The apparatus includes a tubing string forming a production flow path for production fluids between the earth's surface and a location in the well suitable for receiving well production fluids, a power tubing generally parallel to the production tubing and connected to the flow path of the production tubing, and a cross over flow mechanism to divert the flow of production fluids from the power tubing to the production flow path. A lubricant flow path extends from the earth's surface to a location near a pumping apparatus disposed in the power tubing to allow a lubricant to be introduced into the pumping apparatus.

Abstract: A pumping system comprises a pump barrel that is adapted to be placed into a well casing. A plunger is reciprocatably positioned within the pump barrel and has an open top end, a bottom end, and a traveling valve at the bottom end. A connector is coupled to the plunger below the top end. A rod is coupled to the connector and is translatable to reciprocate the plunger within the pump barrel using an upstroke and a downstroke. Further, the top end of the plunger is adapted to direct particulate into the plunger and away from the pump barrel upon each upstroke.
