COMPOSITIONS FOR USE IN DRILLING, CONDITIONING AND RECONDITIONING FLUIDS |
| abstract |
THE INVENTION IN PARTICULAR CONCERNS A SURFACTIVE COMPOSITION WHICH IS INCORPORATED IN THE DRILLING, PACKAGING AND RECONDITIONING FLUIDS IN ORDER TO MINIMIZE THE DAMAGE TO THE OIL LAYERS. IT INCLUDES, BY WEIGHT, 30 TO 70 OF A GLYCOLIC DIESTER OF SODIUM MONOSULFOSUCCINATE, 30 TO 50 OF A QUATERNARY POLYPROPOXYL AMMONIUM CHLORIDE AND 0.1 TO 4 OF A SODIUM ALKYLPHENYL-POLYETHER-SULPHATE; THESE ADDITIVES REDUCE INTERFACIAL TENSION IN PRODUCTION LAYERS AND IMPROVE WATER WETTING AND DEEMULSIONING WHILE BEING THERMALLY STABLE OVER EFFECTIVE INTERVALS. IMPROVED OIL RECOVERY IN THE TREATED LAYER. |
