Abstract

MODERN INVERT DRILLING MUDS CONTAIN A CONTINUOUS OIL PHASE IN WHICH IS DISPERSED AN AQUEOUS PHASE PLUS ANY DESIRED EMULSIFIERS, WEIGHTING AGENTS, FLUID-LOSS ADDITIVES AND ANY OTHER ADDITIVES. THE INVENTION PROPOSES THE USE OF SELECTED ESTERS OF MONOCARBOXYLIC ACIDS HAVING FROM 6 TO 11 CARBON ATOMS AND MONO-AND/OR POLYFUNCTIONAL ALCOHOLS, WHICH ESTERS ARE FLUID AT ROOM TEMPERATURE AND HAVE FLASH POINTS ABOVE 80?C, AS THE OIL PHASE OR A COMPONENT OF THE OIL PHASE OF INVERT DRILLING MUDS, WHICH MUDS ARE PARTICULARLY SUITABLE FOR ENVIRONMENT-FRIENDLY DEVELOPMENT OF PETROLEUM AND NATURAL GAS DEPOSITS.
