Abstract:
An apparatus for use in pumping fluids in a wellbore, the apparatus comprising:(a) a pipe string positioned in the wellbore and extending between a wellhead end of the pipe string and a production end of the pipe string, the pipe string defining an interior fluid path from the wellhead end to the production end; (b) a swivel device connected into the pipe string between the wellhead end and the production end so that an upper portion of the pipe string between the wellhead end and the swivel device may rotate relative to a lower portion of the pipe string between the swivel device and the production end; (c) a lower connector for connecting the lower portion of the pipe string with a stator of a rotary pump positioned at the production end of the pipe string such that a fluid which is pumped by the pump is conducted through the interior fluid path of the pipe string; and (d) an upper connector for connecting the upper portion of the pipe string with a rotor of the rotary pump such that rotation of the upper portion of the pipe string will result in rotation of the rotor and in pumping of the fluid by the pump.
