Abstract
An example embodiment of a pipe-in-pipe electric motor assembly includes a drilling string that includes an inner pipe, an outer pipe, and an electric motor. The electric motor is provided with power supplied by the inner pipe and the outer pipe acting at least as conductors. A latching mechanism connects the drilling string and an electric motor output shaft. The electric motor output shaft is driven by the electric motor. The latching mechanism prevents the electric motor output shaft from rotating slower than the drilling string and associated methods.
