n: a device that secures, or fastens, equipment. In producing wells with sucker rod pumps, a gas anchor is a special section of perforated pipe installed below the pump. It provides a space for gas to break out of the oil. In offshore drilling, floating drilling vessels are often secured over drill sites by large anchors like those used on ships. For pipelines, a device that secures pipe in a ditch.

n: Means of holding the deadline to the derrick or substructure. Usually this is the primary element of the weight indicator

a device with slips that holds equipment in the wellbore.

n: The appliance installed in the dead end of drill cable and used to alleviate shock and wornout. Make the counting of weight indicator accurate.

n: The difference of bit load measured by weight indicator in drill floor and bit load measured by MWD.

n: the weight in the fluid which is represented by the weight indicator when the pipe is hung on the hook not touching the bottom of the well

n: the instrument used to disply the weight of all the pipe strings in dual completion

n: the wight of the drill steam showed on the weight indicator under the flotational process

n: a trademarked name for a rig weight indicator. See also weight indicator.

n: 1. position of the rigs weight indicator where hook load is zero.2. position of an engines transmission when the engines flywheel or other power transmission device is not being turned by the engine.

n pi: 1. value that indicates hook load or force, read from a weight indicator;1 point = 1,000 pounds, or 500 decanewtons. 2. in mud density measurement, the portion of the muds weight expressed in decimal points. For example, a mud that weighs 12.2 pounds per gallon (1,461.8 kilograms per cubic metre) weighs two points more than 12 pounds ( 1,438 kilograms). Also, if a 12.2 potmd-per-gallon muds density is increased to 12.5 pounds per gallon (1,497.8 kilograms per cubic metre),the density has been raised by 3 points.
