Abstract: A positive displacement motor (PDM) is provided comprising an outer housing, a thermoplastic stator and a rotor. The PDM may additionally include a mechanism that allows the stator to be removable from the PDM when the PDM is not in operation and resists rotational movement of the stator with reference to a longitudinal axis of the stator and axial movement of the stator along the longitudinal axis of the stator when the PDM is operating, and a rotor disposed within the stator and configured to rotate within the stator when a fluid flows through the stator.

Abstract: A downhole tool for cleaning and sealing a wellbore includes a wash tool configured at a downhole end of the downhole tool to generate pulses of a first fluid at a first frequency and a first pressure for washing a target interval of a wellbore. The downhole tool further includes a plugging tool configured uphole or downhole from the wash tool to generate pulses of a second fluid at a second frequency and a second pressure for depositing a sealing plug at the target interval of the wellbore. The second fluid has a higher viscosity than the first fluid, the second frequency is lower than the first frequency, and the second pressure is higher than the first pressure.

Abstract: Provided is a method for connecting coiled tubing strings, as well as a flexible stabbing snake. In one aspect, the method for connecting coiled tubing strings includes lowering a downhole end of a first coiled tubing string within a wellbore, and coupling an uphole end of the first coiled tubing string to a downhole end of a second coiled tubing string at a location between a coiled tubing injector and the wellbore to form a combined coiled tubing string. In at least one aspect, the method further includes lowering the combined coiled tubing string within the wellbore.
