n: the gasoline extracted from natural gas by putting the gas into contact with oil in a vessel and subsequently distilling the gasoline from the heavier oil.

gasoline extracted from wet natural gas by putting the gas in contact with oil.

n: a method by which petroleum-bearing limestone or other formations are put into contact with an acid to enlarge the pore spaces and passages through which the reservoir fluids flow.

n: a force of attraction that causes molecules of one substance to cling to those of a different substance.

n: The force which holds together unlike molecules.

attractive forces between unlike molecules or compounds. Example – the attractive forces between water molecules and the walls of a clean glass tube are stronger than the cohesive forces;this leads to an upward turned contact or meniscus at the wall.

n: an atmospheric fin tube exchanger that utilises air for cooling. Ambient air contacts the external fins by fanforced or natural draft. Also called air-fin unit or aerial cooler.

n: A large BOP (q.v.) valve that forms a seal in the annular space between the wellbore and the drill pipe. It is usually installed above the ram type preventers in the BOP stack.

a elastomer bag or donut type seal, pushed into contact with the pipe or tools in the blow out preventer (BOP). It is designed to seal around pipe or any other irregular surface tool (packers, guns, pumps, etc.) that may be in the BOP. May also be called

n: natural gas that overlies and contacts crude oil in a reservoir. Where reservoir conditions are such that the production of associated gas does not substantially affect the recovery of crude oil in the reservoir, such gas may also be reclassified as non-associated gas by a regulatory agency. Also called associated free gas. See gas cap.

the natural gas which occurs with crude oil. It may be free or dissolved. When it occurs as free gas, it may be called unassociated gas.

n: in pipelining, the pumping of a quantity of crude or product of one weight next to one of different weight or type. Usually, a small amount of mixing occurs where the two batches come in contact.

n: any logging device whose operation depends on a portion of the logging tool touching the wellbore.

n: The ratio between the sum of the teeth width of cone bit and the length of contact busbar wire in the downhole.

n: a type of mobile offshore drilling unit (MODU) that has a part of its structure in contact with the seafloor when it is on site and drilling a well. The remainder of the rig is supported above the water. The rig can float. however, allowing it to be moved from one drill site to another. Bottom-supported units include submersible rigs and jack up rigs. See mobile offshore drilling unit.
