An artificial lift assembly and method relating thereto is designed to prevent inadvertent electrical discharge caused by fluids flowing through an electrical submersible pumping system, which is part of the assembly. The assembly uses a rupture disc to prevent fluid flow during introduction of the assembly into a wellbore and a dart and sleeve to prevent fluid flow during removal of the assembly from the wellbore.

Artificial lift assembly

A method of producing a well fluid includes securing a motor to a string of outer tubing and lowering the outer tubing and motor into the well. A rotary pump is secured to a string of inner tubing and lowered into the outer tubing. The pump stabs into cooperative engagement with the motor. Supplying power to the motor rotates the pump, causing well fluid to flow into the outer tubing to an intake of the pump, which pumps the well fluid through the inner tubing to an upper end of the well. Removing the well fluid allows gas to flow up an annulus surrounding the outer tubing to the upper end of the well.

High velocity string for well pump and method for producing well fluid

A through tubing conveyed electrical submersible pumping system for use in a wellbore. The system includes a tubing string with an attached deployed drive system having a pump motor and a pump engaging receptacle, a pumping assembly insertable into the tubing deployed system, and sealing elements on both the tubing string and pumping assembly. Engaging the sealing elements while inserting the pumping assembly forms a seal. The system further includes mating latch members on the pumping assembly and the tubing string, the latch members selectively activated by engaging one another. The latch may include locking fingers disposed on the pumping system and a shoulder protruding into the tubing string; wherein inserting the pumping system into the tubing deployed system locking fingers with the shoulder for securing the pumping system to the tubing string.
