Abstract
The mechanical shaft lock can include one or more shear pins. When an end of the shear pin, e.g., shear pin head, lines up with one or more shearing slots on the MSL or pump shaft, the shear pin engages and stops the rotation of the pump shaft and motor attached to the pump. The shaft lock can be engaged for installing an ESP, disengaged for production after installing by breaking the shear pin upon start-up, and re-engaged for removing the ESP from the wellbore. In some embodiments, the MSL may be configured to be disengaged and re-engaged to deal with well kicks.
