| Zusammenfassung: | A method of drilling a subterranean formation includes drilling the subterranean formation with a drilling fluid including a carbonate base fluid and an aqueous base fluid. The carbonates may be selected from ethylene carbonate, propylene carbonate, glycerol carbonate, butylene carbonate, 1,3-propylene carbonate, dialkylcarbonates, dimethylcarbonate, and mixtures thereof. Drilling fluids may include a carbonate base fluid, an aqueous base fluid and an optional base oil. |
