Abstract
There is provided the use of alkylhydroxylamines (AHA), and in particular, N,N-diethylhydroxylamine (DEHA), as an oxygen scavenger for reducing free dissolved oxygen in drilling fluid which is substantially free of erythorbate, erythorbic acid, or stereoisomers thereof. The AHA may be used to reduce the free dissolved oxygen in order to reduce undesirable corrosion or degradation caused by free dissolved oxygen. The AHA may be combined with a suitable diluent and/or antifreeze.
