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

n: a form of carbon characterised by a high absorptive and adsorptive capacity for gases, vapours, aIM1 colloidal solids.

n: a reaction in which an element has been changed into an unstable isotope during bombardment by neutrons.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

a chemical, heat, radiation, or mechanical action that starts or accelerates a chemical reaction.

A corrosion state where a metal is corroding without control by a reaction product (or corrosion product layer).

n: The circulating fluid for drilling. It content the drilling fluid both in the wellbore and surface circulating system.
