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.

gas anchor or a separator used in front of a pump to deflect most of the free gas to improve pump efficiency.

n: the small-diameter tube extending below the pump suction of a sucker rod pump, usually inside the mud anchor, as in a poor boy" gas anchor.

a tube from the intake of a pump that extends further into the liquid column of the well, to keep gas out of the pump.

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: a tube mounted at the bottom of a sucker rod pump and inside a gas anchor to provide a conduit into the pump for well fluids that contain little or no gas.

a siphon tune on a downhole pump.

n: a large-diameter pipe installed outside a gas anchor to reduce or eliminate the entrance of solids into a sucker rod pump.

a enlarged area that promotes solids settling prior to a fluid entering the pump.
