the percent by weight loss of exposing a sample of material to an excess of acid.

n: The process in which the bit continually breaks the formation and deepend the wellbore. It is controled by the driller who operates the brake crank and set down the drilling string to keep definite weight on bit.

the weight of a string in air without the effect of buoyancy provided by wellbore fluids.

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: a weight installed in a tank to which the guide wires or cables for an automatic tank gauge float are attached to hold them taut and plumb.

n: (1) in designing or ordering hoisting (lifting) equipment, the maximum weight that the equipment will be able to safely lift. (2) on diesel electric rigs, the maximum amount of electric power that the generators will have to produce to adequately power the rig.

n: Mixed iron ore and barite to reach the density of 4.20 and coincide with API criterion.

n: the pressure exerted by the weight of the atmosphere. At sea level, the pressure is approximately 14.7 pounds per square inch (101.325 kilopascals),often referred to as 1 atmosphere. Also called barometric pressure.

n: a number that approximates the number of protons plus the number of neutrons in an atom;it expresses the relative weights of atoms.
