Slang for gas separator. see poor boy.

1. The device used to remove unwanted gas from a liquid, especially from drilling fluid.
2. A device that removes air or gases (methane, h2s, co2 and others) from drilling liquids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the [...]

A bradenhead pack; no packer, very limited pack pressure capability. see poor boy.

Homemade; something done on a shoestring basis.

A remedial cementing operation designed to force cement into leak paths in wellbore tubulars. the required squeeze pressure is achieved by carefully controlling pump pressure. squeeze cementing operations may be performed to repair poor primary cement jobs, isolate perforations or repair damaged casing or liner.

A channel in the cement, usually caused by poor displacement of drilling mud.

A drive mechanism where a drop in pressure releases gas from the oil that helps drive the oil towards the wellbore. it is a poor recovery mechanism.

The process of raising or lifting fluid from a well by injecting gas down the well through tubing or through the tubing-casing annulus. injected gas aerates the fluid to make it exert less pressure than the formation does; consequently, the higher formation pressure forces the fluid out of the wellbore. gas may be injected continuously [...]
