Abstract: Oil field services apparatus and method. The apparatus comprises a conveyance system operable for lowering and retrieving a downhole tool in and out of a wellbore. The conveyance system comprises a drum operable for rotating and receiving a line connectable with the downhole tool, a motor-generator mechanically connected with the drum, and an energy storage electrically connected with the motor-generator. The motor-generator may be operable for receiving electrical energy to impart torque to the drum and receiving torque from the drum to generate electrical energy. The energy storage may be operable for storing electrical energy received from the motor-generator.
