closing pressure at depth for a gas lift valve.

abbr: 1. Pit Volume Totalizer. 2. pressure, volume, and temperature. See pressure, volume. and temperature analysis.

pressure volume temperature data for fluids.

abbr: pressure, volume, and temperature analysis.

n: 1. a vessel of known size, often equipped with a thermometer, used to determine or to compare densities of solids or liquids. 2. in core analysis, the cylindrical steel chamber filled with mercury used to measure the bulk volume of a core sample. When a core sample is placed in the pycnometer, the mercury that it displaces spills into a dish and is weighed. By dividing the weight of the displaced mercury by the density of the mercury, the bulk volume of the sample can be determined.

n pi: particles produced directly by volcanic action when gases within molten lava expand rapidly and the water suddenly flashes into steam, blasting the molten mass into tiny splinters of solidifying glass. The hot particles eventually come to rest in thick blankets of cooling cinders, called ash.

particles (to chucks) of molten igneous rock ejected from a volcanic vent during an eruption.

a very high temperature perforating explosive.

the percent of the total volume that the internal phase comprises.

a product providing utility without variability (Taguchi).

n: under the given temperature and pressure, the ratio of gas volume and the total volume of liquid and gas in the foam.
