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.

Drilling composition, process for its preparation, and applications thereof

The present invention relates to a drilling composition comprising an organic phase having at least one linear or branched, cyclic or non-cyclic, saturated hydrocarbon, at least one ester, water or aqueous phase, and at least one additive. The present invention additionally relates to the use and preparation of the 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, and to a process for production of oil and/or gas.

The present invention concerns a method for the production of carboxylic acid esters containing the steps: The present invention also concerns the use of a ship.

Method for the production of carboxylic acid esters during a transport

The use is described of oligoglycerol fatty acid esters, produced from

Oligoglycerol fatty acid ester lubricant additives for drilling fluids

The present invention relates to a crosslinked glycerol or oligoglycerol ester which can be obtained by crosslinking a non-crosslinked glycerol or oligoglycerol ester which can be obtained by reacting an

Crosslinked glycerol or oligoglycerol esters, and use thereof as an additive in drilling fluids

Oligoglycerol esters of fatty acids, preferably of unsaturated fatty acids, can be used as thickeners in oil-based drilling mud compositions. The oligoglycerides are preferably employed in invert drilling muds, the oily phase of which contains paraffins.
