Abstract
A system for determining the ability of a selected motor to function in a wellbore preferably includes an input device, a data storage device and a program. The program is preferably configured to determine an expected motor load based on motor input data and application input data. Using the expected motor load, the program determines a projected motor temperature increase. The program adds the projected motor temperature increase with the wellbore temperature to determine a projected operating temperature. The projected operating temperature is compared with the maximum recommended operating temperature of the selected motor, or a list of candidate motors, to determine the ability of the selected motor to function in the wellbore.
