Title
(EN) SURFACTANT FOR STIMULATION OF WELLS, REDUCE VISCOSITY AND THE ACCRETION RATE, AND MANUFACTURING PROCESS THEREOF

Abstract
(EN)
The invention relates to a surfactant derived from combining an aliphatic hydrocarbon distillate solvent, a nonionic surfactant agent, and a polar solvent family of glycols. The polar solvent allows the homogeneity of the mixture between the aliphatic hydrocarbon distillate solvent and the nonionic surfactant. The invention proposes to destabilize the natural emulsion of the heavy and extra heavy crudes facilitating the dispersion of the crude oil in the drilling fluid, thereby avoiding the formation of the plastic amalgam causing the problems inherent to the horizontal drilling heavy and extra heavy of oil fields.
(FR)
L'invention concerne un tensioactif dérivé de la combinaison d'un solvant de distillat d'hydrocarbures aliphatiques, d'un agent tensioactif non ionique et d'une famille de solvants polaires de glycols. Le solvant polaire permet l'homogénéité du mélange entre le solvant de distillat d'hydrocarbures aliphatiques et le tensioactif non ionique. L'invention propose de déstabiliser l'émulsion naturelle des bruts lourds et extra-lourds, facilitant ainsi la dispersion du pétrole brut dans le fluide de forage, ce qui permet d'éviter la formation de l'amalgame de plastique provoquant les problèmes inhérents au forage horizontal des bruts lourds et extra-lourds des champs pétrolifères.
