the volume a solid occupies when added to a fluid divided by its weight. m3/kg or gal/lb.

n: in drilling operations, gas that returns to the surface with the drilling mud in measurable quantities but does not cause a kick. Increases in background gas may indicate that the well is about to kick or has kicked.

the radiation intensity existing in the environment before a specific radiation source is considered.

n: a procedure, based on competitive bidding, used to acquire oil and gas leases to federal lands within areas designated by USGS as known geologic structures (KGS) or on offshore federal lands.

abbr: kilogram.

abbr: known geologic structures.

n: (kg-m) in the metric system, a unit of measure of twisting force, of a strand;other wires in the strand are laid around this wire. or torque. The amount of energy required to move I kilogram I metre vertically.

n: see mud weight.

n: The mass per unit volume of a drilling fluid, synonymous with mud density. Weight is reported in lbm/gal (also known as ppg),kg/m3 or g/cm3 (also called specific gravity or SG),lb/ft3 or in hydrostatic gradient, lb/in2/ft (psi/ft) or pptf (psi/1000 ft).

the specific gravity of the mud expressed in lb/gal, kg/m3, etc.

n: (N) an SI unit that expresses force. One newton equals 1 metre-kilogram per second per second (mokg/s2),which is the force required to move 1 kilogram a distance of 1 metre at a velocity of 1 second squared.

n: the appearance of oil or gas in cuttings. samples, or cores from a drilling well.

cuttings or returning fluids with a hydrocarbon content above normal background level.
