摘要： The present invention relates to a drilling composition comprising I) an organic phase comprising components i. from about 20 wt. % to about 99.999 wt. %, based on the total weight of components i. and ii., of at least one linear or branched, cyclic or non-cyclic, saturated hydrocarbon, ii. from about 0.001 wt. % to about 25 wt. %, based on the total weight of components i. and ii., of at least one ester, II) from 0 to about 50 wt. %, based on the total weight of the composition, of water or aqueous phase, III) from 0 to about 60 wt. %, based on the total weight of the composition, of at least one additive, wherein the sum of the weight components I) to III) is 100 wt. %, to a process for preparation of a drilling composition, to uses of a drilling composition, to a drilling system, to a process for making a borehole, to a process for conveying cuttings, to a process for treating a drill head, to a process for production of at least one of oil and gas.

摘要： The incorporation of highly refined, low viscosity index base oils along with a polymeric thickener produces a final readily biodegradable fluid with a significantly high viscosity. The present invention allows the formulation of a high viscosity readily biodegradable fluid where the vast majority of the fluid is mineral oil. Previous uses of mineral oils only allowed for formulation of substantially lower viscosity readily biodegradable fluids.
