Pertaining to the environment and conditions of organisms living at the water bottom, or benthos. Also called benthonic.
Industry:Oil & gas
Pertaining to the depositional environment of the deepest area of the ocean basins, the abyss. The depositional energy is low, the abyssal plain is flat and nearly horizontal, and fine-grained sediments are deposited slowly by waning turbidity currents or from suspension in the water. The water is thousands of meters deep (> 2000 m) (6520 ft), so the water is cold and sunlight is minimal.
Industry:Oil & gas
Pertaining to the adhesion of a liquid to the surface of a solid. In water-wet conditions, a thin film of water coats the surface of the formation matrix, a condition that is desirable for efficient oil transport. Treatments that change the wettability of the formation from water-wet to oil-wet can significantly impair productivity.
Industry:Oil & gas
Pertaining to techniques in which the same quantity is measured at different times in the life of a reservoir. Normally the only change in a time-lapse measurement or survey will be due to changes in water or gas saturation. Thus, a comparison of two logs run at different times, such as a year apart, should simply reflect the change in fluid saturations in the pore space. The most common time-lapse logs are made with pulsed neutron capture, pulsed neutron spectroscopy and borehole gravity measurements.
Industry:Oil & gas
Pertaining to structures in which the shapes of adjacent layers resemble or conform to one another. Folds of rock layers that have similar mechanical properties or competence tend to be harmonic, with little change in fold shape, symmetry or wavelength from one layer to the next.
Industry:Oil & gas
Pertaining to structures in which the shapes of adjacent layers differ or do not conform to one another. Folds of rock layers that have different mechanical properties or competence tend to be disharmonic, with a change in fold shape, symmetry or wavelength from one layer to the next.
Industry:Oil & gas
Pertaining to strata that are relatively ductile and tend to flow under stress rather than deform by brittle faulting or fracturing. The bed thickness of incompetent beds tends to change during deformation.
Industry:Oil & gas
Pertaining to sound. Generally, acoustic describes sound or vibrational events, regardless of frequency. The term sonic is limited to frequencies and tools operated in the frequency range of 1 to 25 kilohertz.
Industry:Oil & gas
Pertaining to seismic events that show continuity from trace to trace. Seismic processing to enhance recognition of coherent events and emphasize discontinuities such as faults and stratigraphic changes has gained popularity since the mid-1990s.
