Controlling salt contaminated drilling fluids with ethylene dicarboxylic acid |
| abstract |
Method of controlling the rheology of a fresh water drilling fluid contaminated with salt by incorporating therein an ethylenedicarboxylic acid in an amount of from about 0.5 to about 6 pounds per after being applied to a soiled substrate. Soil adheres to the tacky film which, as a method employing such a contaminated drilling fluid and containing said ethylenedicarboxylic acid, and a drilling fluid additive consisting of said ethylenedicarboxylic acid. |
