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: Examination and testing of the drilling fluid to determine its physical and chemical properties and condition.

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 floating marker used in a spread mooring system to position each anchor of a semi-submersible rig or drill ship. See spread mooring system.

n: a packer designed for sitting on a pipe that rests on bottom, such as a tail pipe or liner. See packer:

n: the pattern of minute projections from a metal surface produced by sandblasting, shot blasting, or chemical etching to enhance the adhesiveness of surface coatings.

n: See below packer bourdon tube case.

n: a fishing tool installed inside washover pipe to prevent a fish stuck off bottom from falling to bottom during a washover. Slips on the anchor washpipe spear engage the inside of the washover pipe as the pipe travels downhole around the fish.
