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 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.

Oligoglycerol fatty acid ester thickeners for oil-based drilling fluids

The invention relates to a process of cleaning boreholes, boring equipment and borings with an aqueous cleaning of one more lithium salts of alkyl sulfates of formula (I):R&#x2014;O&#x2014;SOLi&#x2003;&#x2003;(I)in which R is a saturated, unsaturated, branched or linear alkyl group containing 8 to 22 carbon atoms, preferably the lithium salts of alkyl sulfates are comprised of a mixture of those in which R is a saturated, linear alkyl groups having 8 to 14 carbon atoms.

Lithium salts of fatty alcohol sulphates for cleaning boreholes, boring devices and borings

A well servicing composition containing an aqueous phase and an oil phase and an ether carboxylic acid of the formula:RO(CHCHO)(CHCHRO)CH&#x2014;COOXwherein, R is a saturated or unsaturated, branched or unbranched alkyl or alkenyl group containing 6 to 22 carbon atoms, x is a number from 1 to 20 and y is 0 or a number from 1 to 20, provided that the sum of x and y is at least 1 and at most 25, Ris an alkyl group containing 1 to 4 carbon atoms and X comprises at least one member selected from the group consisting of a hydrogen atom, monovalent cations and polyvalent cations.

Borehole treating substance containing ether carboxylic acids

The invention relates to a borehole treatment composition containing an aqueous phase and a non-aqueous oil phase, emulsifiers and, where appropriate, further customary additives, the non-aqueous oil phase containing at least one of

Borehole treatment agent containing low-toxic oil phase

A process for imparting lubricity to an aqueous drilling fluid used in geological exploration involving: (a) providing an aqueous drilling fluid; (b) providing a lubricant component containing a partial glyceride of predominantly unsaturated fatty acids having from about 16 to 24 carbon atoms; and (c) introducing the partial glyceride into the aqueous drilling fluid.
