1. n. [Drilling Fluids]
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
- sulfite anions to remove molecular oxygen
- sulfide removal by oxygen or peroxide
- air oxidation of lignite to create more humic acid
- sulfate reducing bacteria that generate sulfide ions by biological redox reactions
- chromate ions being converted to chromic ion in a mud system.
