Algerian.

n: the algebraic sum of the actual compressibility of a liquid and the volume change per unit volume of the confining container caused by a unit change in pressure at constant temperature.

n: (CAODC) a trade association that represents virtually 100% of the rotary drilling contractors and the majority of well service rig operators in western Canada. The relations, and other matters of interest to members. Address: 540 5th Avenue SW, Suite 800;Calgary, Alberta, Canada T2P OM2;(403) 264-4311;fax (403) 263-3796.

n: A commercial association. Its headquarters is located at Calgary, Albert, Canada. This association practically stands for rotary drilling contractors and oil well operator in the west of Canada.

n: any of the algae of the class Bacillariophyceae, noted for symmetrical and sculptured siliceous cell walls. After death, the cell wall persists and forms diatomite. Diatoms first appeared in the Cretaceous period and still live today.

n: an earthy deposit made up of the siliceous cell walls of onecelled marine algae called diatoms. It is used as an admixture for cement to produce a lowdensity slurry.

silica particles from Diatom beds. Used as a filtering media and as an additive to cement.

n: a rock of biochemical origin, which is composed of the siliceous (glassy) shells of microscopic algae called diatoms.

n: (HLB) an expression of the relative attraction of an emulsifier for water and oil, determined lalgely by the chemical composition and ionisation characteristics of a given emulsifier. The HLB of an emulsifier is not directly related to solubility, but it determines the type of emulsion that tends to be formed. It is an indication of the behavioural characteristics and not an indication of emulsifier efficiency.

microscopic living organisms such as protozoa, bacteria, viruses, algae and fungi.

n: schlumberger wireline tool that breaks down the naturalgamma rayspectrum to differentiate between minerals such as potassium, thorium and uranium. Useful for reservoir declieaqtion, well to well correlation, cation exchange capacity studies,igneous rock r
