n: the equipment for transporting and using coiled tubing, including a reel for the coiled tubing, an injector head to push the tubing down the well, a wellhead blowout preventer stack, a power source (usually a diesel engine and hydraulic pumps),and a control console. A unique feature of the unit is that it allows continuous circulation while it is being lowered into the hole. A coiled tubing unit is usually mounted on a trailer or skid.

n: locking of a cone on a roller cone bit so that it will not turn when the bit is rotating. Cone skidding results in the flattening of the surface of the cone in contact with the bottom of the hole.

n: The phenomenon that the cone of bit is freezed in.

n: a small platform fabricated from pipe or bar stock and steel plate onto which a meter and a manifold are mounted.

n pi: metal-toed shoes or boots with nonskid, corrosion-resistant soles worn by oilfield workers to minimize falls and injury to their feet.

n: Its feature is corrosion prevention and antislip.

n: a low platform mounted on the bottom of equipment for ease of moving, hauling, or storing.

n: moving a rig from one location to another, usually on tracks where little dismantling is required.

move a well to a close-by locations with minimum rig down of equipment.

n: It can achieve the entire delivery to rig.

n: a hard metal pad mounted on a borehole contact logging tool that contacts the well bore and prevents wear to the rest of the tool.

v: to move a rig with a standard derrick from the location of a lost or completed hole preparatory to starting a new hole. Skidding the rig allows the move to be accomplished with little or no dismantling of equipment.
