n: any chemical compound. one element of which is hydrogen, that dissociates in solution to produce free hydrogen ions. For example, hydrochloric acid. HCI, dissociates in water to produce hydrogen ions, H+, and chloride ions, CI-. This reaction is expressed chemically as HCI + H+ + CI- . See ion.

a reactive material with a low pH. Common oilfield mineral acids are HCl and HCl/HF.

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 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.

n: one of usually two, three, or more mud tanks that holds drilling mud that is being circulated into a borehole during drilling. They are called active tanks because they hold mud that is currently being circulated.
