Oilfield

coning

Oil & gas; Oilfield

The change in oil-water contact or gas-oil contact profiles as a result of drawdown pressures during production. Coning occurs in vertical or slightly deviated wells and is affected by the ...

The change in direction of rotation that occurs when a spinner flowmeter tool is moving in the same direction, but faster, than the fluid. When the tool is stationary, moving against the fluid flow, ...

acid effect

Oil & gas; Oilfield

The change in a pulsed neutron capture measurement produced by acidizing a carbonate formation. Acidizing tends to increase the porosity as well as leave chlorides in the formation, thereby ...

excess cement

Oil & gas; Oilfield

The cement slurry remaining in the wellbore following a cement squeeze in which the objective is to squeeze slurry into the perforations and behind the casing or liner. The volume of slurry required ...

squeeze

Oil & gas; Oilfield

The careful application of pump pressure to force a treatment fluid or slurry into a planned treatment zone. In most cases, a squeeze treatment will be performed at downhole injection pressure below ...

area open to flow

Oil & gas; Oilfield

The calculated flow area provided by perforations across a specific zone of interest. The resulting value is used to calculate pressure drops and fluid-flow performance.

cylinder

Oil & gas; Oilfield

The barrel of the sucker rod pump. The plunger travels up and down in the cylinder. The plunger and the barrel operate as a piston mechanism to lift reservoir fluids into the subsurface pump. A ...
