abbr: cubic centimetre.

n: (cm3) a commonly used unit of volume measurement in the metric system equal to 10-6 cubic metre, or I millilitre. The volume of a cube whose edge is 1 centimetre.

n: an iron-black mineral of composition FeTiO3 or Feo�TiOx, with a specific gravity of about 4.67, sometimes used for increasing the density of oilwell cement slurries.

n: A dense mineral whose specific gravity is 4.67 g/cm3, composed of FeO·TiO2. Ilmenite is used as a weighting agent for cement and mud.

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: A mineral composed of ferrous carbonate, FeCO3, and having 3.8 g/cm3 specific gravity. It is found as an accessory mineral in some shales and carbonate rocks and also in some barite and hematite ores. FeCO3 is readily soluble in acids and breaks down slow

iron carbonate.
