Pressure above which injection of fluids will cause the rock formation to fracture hydraulically.
Industry:Oil & gas
Pooled production from wells or a reservoir. The proceeds of this pooled production are distributed to the participants according to an agreed-upon formula.
Industry:Oil & gas
Phases that can mix and form a homogeneous mixture. Hydrocarbon gases and liquids are commonly miscible.
Industry:Oil & gas
Phenomena involving the transfer of energy from neutrons to nuclei. The reaction rate of neutrons with matter depends on the density of neutrons, their velocity, the nuclear density and the particular interaction cross section. There are four principal neutron interactions that affect formation evaluation: elastic neutron scattering, inelastic neutron scattering, fast-neutron reactions and neutron capture.
Industry:Oil & gas
Phenomena resulting from the transfer of energy from a gamma ray to matter, usually to an electron. The probability of a specific interaction occurring depends on the atomic number of the material and the energy of the gamma ray. In formation evaluation, there are two types of interactions of interest: the photoelectric effect, which indicates lithology, and Compton scattering, which depends on formation density. The third type of interaction, pair production, occurs at energies above those used for logging.
Industry:Oil & gas
Pertaining to waves of elastic energy, such as that transmitted by P-waves and S-waves, in the frequency range of approximately 1 to 100 Hz. Seismic energy is studied by scientists to interpret the composition, fluid content, extent and geometry of rocks in the subsurface. "Seismic," used as an adjective, is preferable to "seismics," although "seismics" is used commonly as a noun.
Industry:Oil & gas
Petroleum with a high content of naphthenic compounds, such as asphaltenes. Asphaltic crude is also known as naphthene-based crude oil when the paraffin wax content is low.
Industry:Oil & gas
Pertaining to variation of the frequency while maintaining the geometry of electromagnetic surveying. In contrast, geometric pertains to keeping the same geometry while varying the frequency.
Industry:Oil & gas
Pertaining to variation of the survey geometry while maintaining the frequency of electromagnetic surveying. In contrast, parametric pertains to keeping frequency the same while varying the geometry.
