n: The process that the cation absorbed by surface of clay particle is displaced by other cation in drill fluid. This character can improve performance of drill fluid.

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: The additive that can interchange the cation absorbed on the surface of clay particle.

n: See cation exchangers.

cation exchange capacity.

n: A process of exchanging one ion for another ion on a charged, solid substrate, such as a natural clay, zeolite or resin. Cation exchange on clay minerals occurs in muds and during mud testing. In muds, various positive ions (for example, Ca+2) on clay sur

ion exchange (cation or anion) where scaling or water hardening minerals such as calcium and magnesium are removed by substitution for sodium.

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
