redox — Oil & Gas Glossary

A contraction of reduction-oxidation, a type of chemical reaction in which one reactant is reduced (gains electrons) while the other is oxidized (loses electrons). Examples of redox mud chemistry are: (1) sulfite anions to remove molecular oxygen, (2) sulfide removal by oxygen or peroxide, (3) air oxidation of lignite to create more humic acid, (4) sulfate reducing bacteria that generate
