Patent

CA 2310477

A well production apparatus includes a down-hole gear pump and a transport assembly to which the gear pump is attached. The transport assembly is formed from a string of modular pipe assemblies having one or more passages for carrying production fluid from the bottom of the well to the surface. The passages can be arranged in a side-by-side configuration, and include pressure and return lines for driving the gear pump. The gear pump includes a hydraulically driven motor that is ganged with a positive displacement gear set. Both the motor and the pumping section have ceramic wear surfaces, the ceramic being chosen to have coefficients of thermal expansion corresponding to the coefficients of thermal expansion of the gear sets. The pumps and rotors have ceramic bushings rather than ball or journal bearings, and are operable under abrasive conditions.
