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 tubular, perforated device attached to the bottom of a sucker-rod pump that helps to prevent gas lock. The device works on the principle that gas, being lighter than oil, rises. As well fluids enter the anchor, gas breaks out of the fluid and exits from the anchor through perforations near the top. Remaining fluids enter the pump through a mosquito bill (a tube within the anchor),which has an opening near the bottom. In this way, all or most of the gas escapes before the fluids enter the pump.

a gas separation device, usually a perforated pipe section, in a beam lift well that helps break gas out of the liquids, preventing gas entry and resultant gas lock of the pump.

n: sections of pipe (such as casing, liner, and tail pipe) in which holes or slots have been cut before it is set.

n: A wellbore tubular in which slots or holes have been made before the string is assembled and run into the wellbore. Perforated tubes typically are used in small-diameter wellbores or in sidetracks within the reservoir where there is no need for the liner

n: putting the casing with hole into the the location of oil layer when drills throuthout of oil layer.
