Oilfield

A technique for analyzing the grain-size distribution of a core sample. A cleaned, disaggregated sample is dispersed in a carrier fluid. The grains cause diffraction of a laser beam directed through ...

single-shot survey

Oil & gas; Oilfield

A technique for acquiring deviation information from a borehole on a slickline. In high-angle wells, a multishot technique is usually used instead.

pressure storage tank

Oil & gas; Oilfield

A tank designed for storing volatile liquids such as gasoline and liquefied petroleum gases (LPG), which generate high internal pressures. A pressure storage tank is commonly spherical. Other types ...

tank table

Oil & gas; Oilfield

A table that shows the tank capacity in barrels as a function of the liquid level inside the tank. A tank table is also called a tank capacity table or gauge table.

lowstand systems tract

Oil & gas; Oilfield

A systems tract overlying a sequence boundary and overlain by a transgressive surface. Characterized by a progradational to aggradational parasequence set, this systems tract commonly includes a ...

highstand systems tract

Oil & gas; Oilfield

A systems tract bounded below by a downlap surface and above by a sequence boundary, commonly abbreviated as HST. This systems tract is characterized by an aggradational to progradational ...

unsteady state

Oil & gas; Oilfield

A system that is in a transient state at the time of a measurement. In the case of permeability measurements on core samples, two transient techniques are used. In the pressure falloff method, the ...
