n: material of high specific gravity formed during the chemical refining treatment of oils by sulphuric acid and usually separable by settling or centrifuging. Also called acid tar.

n: usually refers to drill exploration well in the radioactivity, geochemistry and gravity abnormal area.

n: the measure of the density or gravity of liquid petroleum products in the United States;derived from relative density in accordance with the following equation: API gravity at 60ﾰF = [141.5 + relative density 60/60ﾰF] -131.5 API gravity is expressed in degrees, 1 D. API being equivalent to 1.0, the specific gravity of water. See gravity.

n: A measure of the density of liquid petroleum products, expressed in degrees. It can be derived from the following equation: API gravity (degree) =141.5/specific gravity-131.5

the relative density of a hydrocarbon based on a scale of degrees API. Density in g/cc = (141 / (131 +API)).

n: the number of Btus contained in a cubic foot of natural gas adjusted to reflect the actual water content of the gas at delivered pressure, temperature, and gravity conditions.

gravity n: specific gravity as measured by the Baume scale. Two arbitrary scales are employed: one for liquids lighter than water and the other for liquids heavier than water. This scale is also used to describe the density of acid solutions.

n: either of two arbitrary scales-one for liquids lighter than water and the other for liquids heavier than water-that indicates specific gravity in degrees. bbl abbr: barrel. bbV acre-ft abbr: barrels per acre-foot. bbVd abbr: barrels per day. Bcf abbr: billion cubic feet. Bcf/d abbr: billion cubic feet per day. b/d abbr: barrels per day;often used in drilling reports. BID abbr: barrels per day. BOC abbr: bottom dead centre

n: see residuals.

a fuel oil, normally with high sulfur and high viscosity. API gravity of about 10.5o. Also called Navey Heavy and Number 6 fuel oil.

n: 1. one of several columns made of steel or concrete that serve as the foundation for a rigid offshore platform rig, such as the concrete gravity platform rig. 2.equipment below the waterline of an Arctic submersible rig, thereby protecting the equipment from damage by moving ice.
