n: on a diamond bit, the material (usually powdered and fused tungsten carbide) into which the diamonds are set.

n: The water which is adsorbed or united chemically in the mudstone, gypse or other substances. It cannt flow freely in the natural condition.

water that is trapped in or on the matrix minerals and cannot move.

n: 1. the temperature and pressure at which part of a liquid begins to convert to gas. For example, if a certain volume of liquid is held at constant pressure, but its temperature is increased, a point is reached when bubbles of gas be- gin to form in the liquid. That is the bubble point. Similarly, if a certain volume of liquid is held at a constant temperature but the pressure is reduced, the point at which gas begins to form is the bubble point. Compare dew point. 2. the temperature and pressure at which gas, held in solution in crude oil, breaks out of solution as free gas.

the pressure at which gas begins to break out of an under saturated oil and form a free gas phase in the matrix or a gas cap.

n: 1. a salt of carbonic acid. 2. a compound containing the carbonate radical (CO3) 3. a carbonate rock.

n: The different carbonate of alkaline earth element.

any of the many rocks composed of calcium carbonate (limestone) or magnesium carbonate (dolomite) or other acid soluble rocks with a common CO3-2 ionic charge. The pores may be poorly connected and matrix permeability (non fractures) are often much lower

n: See bit matrix.

n: See bit matrix.

n: The galling metal for glazing diamond bit matrix.

an interconnected pathway through the matrix of the rock or an open fracture or other feature that connects a reservoir and the wellbore.

reactions involving the rock and connate fluids in which parts of the matrix are filled by scale or mineral growths or removed and become high permeability flow channels.

movement of clay particles, usually after partial disintegration of the clay matrix due to absorption of water or reaction to other effects such as ions, velocity, crushing due to overburden, etc.
