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.

Apparatus for producing well fluids from an oil bearing formation penetrated by a well, the apparatus comprising:
- a production tubing string forming a production flow path for production fluids, the production tubing string being adapted to be positioned between the earth's surface and a location in the well suitable for receiving well production fluids;
- a power tubing string having a lower portion and an upper portion, the power tubing string being adapted to extend down the well in a generally parallel relationship with the production tubing string to a location in the well suitable for receiving production fluids into the lower portion of the power tubing string from the well;
- a pumping apparatus disposed in the power tubing string which is adapted to pump well fluids from the well into the lower portion of the power tubing string;
- and
- a cross-over flow mechanism between the lower portion of the power tubing string and the flow path of the production tubing string to divert the flow of production fluids out of the power tubing string and into the flow path of the production tubing string for transfer to the earth's surface.
