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: see riser angle indicator.

n: see riser angle indicator.

n: the price per barrel of certain crude oils such as West Texas intermediate and North Sea Brent, which serves as an indicator of worldwide oil prices.

n: a pressure-sensing element consisting of a twisted or curved tube of noncircular cross section, which tends to straighten when pressure is applied internally. By the movements of an indicator over a circular scale, a Bourdon tube indicates the pressure applied.

n: The explosive made by powder chamber, detector and adherent wire. Usually matched with free joint indicator.

n: a device fitted to a proving tank to indicate the position of the liquid surface in relation to the reference mark corresponding to the nominal capacity of the proving tank, thus enabling the determination of the tanks liquid contents. capacity rating n: a rating equal to the maximum number of cubic feet of gas that will pass through a meter when the pressure differential across the meter equals a 0.5- inch water column and the flowing pressure is 0.25 psig.

n: device used to measure the percentage of combustible gas present in a sample of atmosphere.
