a theory of petroleum generation in which petroleum is thought to have formed from hydrocarbons trapped inside the earth’s crust when the earth was forming. See also Biogenic and Organic theories.

a failure mode that can cause the cancellation-of or immediate-halt-to a project or event. Generally expressed as a percent probability.

n: A formation pressure that is higher than the normal formation fluid hydrostatic pressure.

n: pressure exceeding or falling below the pressure to be expected at a given depth. Normal pressure increases approximately 0.465 pow1ds per square inch per foot of depth or 10.5 kilopascals per metre of depth. Thus, normal pressure at 1,000 feet is 465 pounds per square inch;at 1,000 metres it is 10,500 kilopascals. See pressure gradient.

n: A formation pressure that deviates from the normal formation fluid hydrostatic pressure. Such pressure may be classified as "subnormal" (lower than normal) or "overpressured" (higher than normal).

n: The abnormal pressure per meter in depth, usually express as MPa/m. It is the reference
of density of the mud and the procedure of the casing design.

a pore pressure higher than a column of sea water for that true vertical depth.

adv: on or in a ship, offshore drilling rig, helicopter, or production platform.

n: It is connected above the packer of DST tool, which is used to protect the tubular subs which are installed with bourdon tube.

n: wearing away by friction.

a form of mechanical weathering where loose fragments are transported with water or wind.
