the volume of a wellbore occupied by fluid. When the swept volume varies from the calculated displacement, part of the wellbore may not be actively swept.

n: the proportion by volume of oil swept out of the pore space of a reservoir by the encroachment of another fluid. The displacing fluid may be reservoir water or gas or an injected fluid.

a measurement of how completely a flooding fluid displaces the saturated fluid in a reservoir.

n: 1. a meter in which a piston is actuated by the pressure of a measured volume of liquid, and the volume swept by the piston is equal to the volume of the liquid recorded. 2. a meter in which the measuring element measures a volume of liquid by mechanically separating the liquid into discrete quantities of fixed volume and counting the quantities in volume units.

a material such as a dye, sand, grain, etc., that can be recognized as the fluid is circulated. Useful for determining swept volume of the hole.

an easily identified formation that is used to identify the start of a rock sequence. In the wellbore, a marker is a material placed in the circulating fluid that can be easily seen when the fluid returns to surface – helps identify the swept volume of th

the amount of the wellbore that is circulated by fluid (describes the hold-up and upswept volume).

n: (WEP) a government financed, nonprofit corporation of eleven oil and pipeline companies established during World War II to build desperately needed pipelines such as Big Inch and Little Big Inch.

abbr: War Emergency Pipelines.
