Oilfield

A phenomenon that occurs when gas enters the subsurface sucker-rod pump. After the downstroke begins, the compressed gas reaches the pressure needed to open the traveling valve before the traveling ...

pump-off

Oil & gas; Oilfield

A phenomenon produced when pump submergence into the fluid column is low. A pump-off situation will increase the gas intake, thus reducing the pump efficiency.

carryover

Oil & gas; Oilfield

A phenomenon in which free liquid leaves with the gas phase at the top of a separator. Carryover can indicate high liquid level, damage of the separator or plugged liquid valves at the bottom of the ...

blowdy

Oil & gas; Oilfield

A phenomenon in which free gas leaves with the liquid phase at the bottom of the separator. Blowdy can indicate a low liquid level or improper level control inside the separator.

oxygen activation

Oil & gas; Oilfield

A phenomenon exploited for the purpose of detecting and quantifying the flow of water in or around a borehole based on oxygen activation. Oxygen ( 16 O) can be activated by high-energy neutrons to ...

liquid blocking

Oil & gas; Oilfield

A phenomenon encountered during dry forward combustion in which an oil zone around the production well cannot be pushed forward by the heated oil. The fluid located in this zone is still at the ...

cleanup

Oil & gas; Oilfield

A period of controlled production, generally following a stimulation treatment, during which time treatment fluids return from the reservoir formation. Depending on the treatment, the cleanup period ...
