a flood front breaking through into a producing well.

n: The gauge surface of cone bit. Soldered with TCI or installed with cooktop alloy teeth to keep bit diameter.

n: a hydraulically powered device that can break out or make up tool joints and assure accurate torque. It is fitted with a repeater gauge so that the driller can monitor tool joints as they go downhole, doubly assuring that all have the correct torque. Sometimes called an Iron RoughneckTM, after the manufacturer of one such wrench.

n: an hydraulic pressure operational assembly that go up and down the pipe and assure exactly torque.

n: a manufacturers name for a floor-mounted combination of a spinning wrench and a torque wrench. The Iron Roughneck moves into position hydraulically and eliminates the manual handling involved with suspended individual tools.
