The gear or chain arrangement by which power is transmitted from the prime mover to the drawworks. The mud pump, or the rotary table of a drilling rig

A type of improved recovery in which heat is introduced into a reservoir to lower the viscosity of heavy oils and to facilitate their flow into producing wells. The pay zone may be heated by injecting steam (steam drive) or by injecting air and burning a portion of the oil in place (in situ combustion).

Total Petroleum-initially-in-place is that quantity of petroleum which is estimated to exist originally in naturally occurring accumulations (equivalent to total resources)

Total Petroleum-initially-in-place is, therefore, that quantity of petroleum which is estimated, on a given date, to be contained in known accumulations, plus those quantities already produced therefrom, plus those estimated quantities in accumulations yet to be discovered.

Total Petroleum-initially-in-place may be subdivided into Discovered Petroleum-initially-in place and Undiscovered Petroleum-initially-in-place, with Discovered Petroleum-initially-in-place being limited to known accumulations. It is recognized that all Petroleum-initially-in-place quantities may constitute potentially recoverable resources since the estimation of the proportion which may be recoverable can be subject to significant uncertainty and will change with variations in commercial circumstances, technological developments and data availability. A portion of those quantities classified as Unrecoverable may become recoverable resources in the future as commercial circumstances change, technological developments occur, or additional data are acquired additional data are acquired.

Connection of a satellite subsea development (smaller field) to an existing infrastructure

Two distinct processes produce hydrocarbon gas: biogenic and thermogenic degradation of organic matter. Biogenic gas is formed at shallow depths. In contrast, thermogenic gas is formed at deeper depths by: (1) thermal cracking of sedimentary organic matter into hydrocarbon liquids and gas and (2) thermal cracking of oil at high temperatures into gas. If a gas show is found to be thermogenic in origin, then the possibility exists that the gas derives from a gas cap overlying a down-dip oil leg. That possibility can be further evaluated from specific aspects of the composition of the thermogenic gas

The total pore volume per unit volume of rock
