v: to amass or collect. When oil and gas migrate into porous formations, the quantity collected is called an accumulation.

a highly porous solid, usually a charcoal. Used for adsorption of unwanted materials.

n: term applied to many heat resistant and chemically inert fibrous minerals, some forms of which are used in certain drilling fluids. It finds only limited use because prolonged exposure can cause respiratory illness.

n: Usually refers to the fibre of different length made by asbestos. Usually used as block agent in porous
thief formation.

n: a reef or mound built by small organisms and their remains, such as coral, plankton, and oysters. Originally a waveresistant coral structure served as an anchor for calcareous debris that formed limestone. It was tectonically submerged, or the sea level rose faster than the corals could build it, and it was eventually buried beneath marine shales. A bioherm is often porous enough to hold large accumulations of hydrocarbons, especially if it has been dolomitized. A bioherm is a stratigraphic trap.

a theory of acoustic propagation in porous and elastic media that taken into account fluid behaviors.

n: The plugged zone formed by plug agent in the thin porous formation. The plug agent is added into the drilling fluid.

n: the thickness of drilling mud filter cake.

n: The measurement of the thickness of the filter cake deposited by a drilling fluid against a porous medium, most often following the standard API filtration test. Cake thickness is usually reported in 32nd of an inch.

n: A measure of how reactive to water a clay mineral is.

related to concentration of cations on negatively charged clay surfaces that, when brine is present, can be exchanged/satisfied for/by cations in the brine. The total of exchangeable cations that a porous medium can absorb, expressed in moles of ion charg

n: A kind of white, loose and earthy limestone whose main chemical component is calcium carbonate. Usually used for heavy weight additive of drill fluid.

an often highly porous but lower permeability carbonate composed of fine grained marine sediments such a coccoliths.

n: the procedure by which a quantity of resinous material is squeezed into a sandy formation to consolidate the sand and to prevent its flowing into the well. The resinous material hardens and creates a porous mass that permits oil to flow into the well but holds back the sand at the same time. See sand consolidation.
