n: lighter hydrocarbons that exist as a liquid under reservoir conditions but that effervesce as gas when pressure is released during production.

n: Dissolved gas in wellbore or reservoir fluids. The gas will remain in solution until the pressure or temperature conditions change, at which time it may break out of solution to become free gas.

the natural gas that is dissolved in a crude oil.

a drive mechanism where a drop in pressure releases gas from the oil that helps drive the oil towards the wellbore. It is a poor recovery mechanism.

n: a source of natural reservoir energy in which the solution gas coming out of the oil expands to force the oil into the well bore.

a substance that will dissolve a solid. In the oil field, oil based solvents may range from xylene for asphaltenes and sludges, to kerosene and diesel/xylene mixtures for paraffins.

a commercial tool that measures the fluid depth in a well by use of a reflecting sound wave.

n: an apparatus that detects the presence of an underwater object by sending out sonic or supersonic waves that are reflected back. to it by the object.

n: a logging tool assembly, especially the device in the logging assembly that senses and transmits formation data.

a term usually referring to a logging instrument.

a log that measures the sonic amplitude of a formation to a sound wave. The log is used to locate fractures.
