n: Generally The power is supplied by electric power net. The working machine is drived by AC motor. It belongs to the drilling rig which has no self-sustaining ability.

n: A rig drived by DC which is commutated by SCR.

n: a motor-driven paddle or blade used to mix the liquids and solids in drilling mud.

n: A mechanically driven impeller used to stir the drilling fluid to assist in the suspension of solids, blending of additives, and maintenance of uniform consistency.

a surface piston driven pumping unit, similar to a beam lift unit.

n: a clutch containing an inflatable tube that, when inflated, causes the clutch to engage the driven member. When the tube is deflated, disengagement occurs.

n: a wireline instrument for measuring bottomhole temperature or pressure. It contains a clock-driven recording section and either a pressure element or a temperature element. It is thin enough to pass downhole through small tubing.

n: a professional multinational organisation of persons employed by governmental units responsible for full-time programs of hygiene and worker health and protection. Address: 1330 Kemper Meadow Drive;Cincinatti, Ohio 45240;(513) 742-2020.

a comparable reservoir with many similar characteristics (e.g., lithology, depositional environment, porosity, perm, drive mechanism, produced fluids, etc.) that can be used for behavior projections comparison studies.

n: one type of misalignment in a chain-and-sprocket drive. The shafts are not parallel to each other (they form an angle) in either the horizontal or the vertical plane. This pulls the link plates on one side tighter than those on the other side;thus, one side of the chain and sprockets wears faster than the other. Link plates on only one side of the chain break because of fatigue.
