A novel high pressure high temperature (hpht) aqueous drilling mud composition and process for preparing the same |
| abstract |
What is described herein is an aqueous high-temperature high-pressure (HTHP) stable drilling mud composition comprising (i) about 20 wt. % to about 80 wt. % of 0-60% w/w brine solution; (ii) about 0.1 wt. % to about 3 wt. % of butylated reaction product of p-cresol and dicyclopentadiene, a polymeric hindered phenol based antioxidant; (iii) about 0.1 wt. % to about 10.0 wt. % of triethanol amine, a chelating agent; (iv) (a) about 0.1 wt. % to about 10 wt. % of rheology modifier (RM); and/or (b) about 0.5 wt. % to about 30 wt. % of fluid loss additive (FLA); (v) about 20 wt. % to about 80 wt. % of weighting agent; (vi) about 0 wt. % to about 20 wt. % of drilling solid; and (vii) about 0 wt. % to about 50 wt % of water. |
