Title (EN) INVERT EMULSION DRILLING FLUIDS
(FR) FLUIDES DE FORAGE DE TYPE ÉMULSION INVERSE
Abstract:
(EN) A composition includes an oil phase; a water phase emulsified in the oil phase; a viscosifier including a carbon chain and a polar group disposed along the carbon chain; and a hydrophobic nanomaterial having an average particle size of less than about 1μm. The hydrophobic nanomaterial including a silane or siloxane molecule having a nonpolar chain disposed on a surface thereof.
(FR) Cette invention concerne une composition comprenant une phase huileuse; une phase aqueuse émulsifiée dans la phase huileuse; un agent de viscosité contenant une chaîne carbonée et un groupe polaire situé le long de la chaîne carbonée; et un nanomatériau hydrophobe ayant une taille de particule moyenne inférieure à environ 1 µm, le nanomatériau hydrophobe comprenant une molécule de silane ou de siloxane ayant une chaîne non polaire située sur une de ses surfaces.
