n: a type of compressor valve in which springs and disks are used to open and close the valve.

n: a suspension of extremely fine particles in a liquid (such as colloids in a colloidal solution).

n: Subdivision of aggregates. Dispersion increases the specific surface of the particle, which results in an increase in viscosity and gel strength.

a mixture of a internal phase of solids, droplets or bubbles that stay relatively suspended in a continuous fluid.

the distance between the wellhead and the top of a vertical line from the bottom hole location to the wellhead elevation at the surface.

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.

n: a measurement of the speed with which a volume of cement slurry or mud is pumped down the hole.

n: a spherical or cylindrical object that is a component part of a pipe prover that moves through the prover pipe. The displacer has an elastic seal that contacts the inner pipe wall of a prover to prevent leakage. The displacer is made to move through the prover pipe by the flowing fluid and displaces a known measured volume of fluid between two fixed detecting devices.

n: natural gas that is in solution with crude oil in the reservoir.

Oil Ratio: the amount of gas contained in the oil (in std ft3/bbl). This value can change if one fluid is produced faster than the other or if one fluid is re-injected.

n: 1. a product of distillation, i.e., the liquid condensed from the vapor produced in a still. Sometimes called condensate. 2. heavy gasoline or light kerosenes used as fuels.
