A method for preparing a thermally stable well servicing fluid in the form of an oil-in-water (O/W) macroemulsion, a water-in-oil (W/O) macroemulsion or a water-in-oil (W/O) microemulsion at the well drilling location is provided. The servicing fluid is prepared by mixing a hydrocarbon phase, a water phase and a surfactant phase to obtain either an O/W macroemulsion, a W/O macroemulsion or a W/O microemulsion. The surfactant phase comprises a first surfactant and/or a second surfactant. The first surfactant comprises a fatty acid mixture and a hygroscopic first additive. The second surfactant comprises a C4-C6 alcohol. Whether or not an O/W macroemulsion, W/O macroemulsion or a W/O microemulsion is produced is determined by the concentration of the phases, the first surfactant, the second surfactant and the timing upon which the first additive, water phase and second surfactant are introduced to the mixture.

Process for preparing thermally stable oil-in-water and water-in-oil emulsions

A surfactant package for a water-in-hydrocarbon emulsion includes a fatty acid component; a fatty acid salt component; an alcohol component and a salt of carboxylic acid. Emulsions formed using this surfactant package are stable and have ratios of water to surfactant of at least about 3.

Surfactant package and water in hydrocarbon emulsion using same

A water-in-hydrocarbon emulsion includes a water phase, a hydrocarbon phase and a surfactant, wherein the water phase is present in an amount greater than or equal to about 5% vol. with respect to volume of the emulsion, and the water phase and the surfactant are present at a ratio by volume of the water phase to the surfactant of at least about 1. A method for preparing the emulsion is also provided.
