Method for improving high temperature rheology in drilling fluids |
| abstract |
A method for enhancing the rheology of drilling fluids that is effective for any mud weight "clay-free" invert emulsion drilling fluid, even when drilling at high temperatures. The improved rheology is effected with addition of a silicon oil to the drilling fluid. A nonlimiting example of such a rheology additive comprises polydimethylsiloxane. |
