Title (EN) INVERT EMULSION WELLBORE FLUIDS AND METHOD FOR REDUCING TOXICITY THEREOF
(FR) FLUIDES DE PUITS DE FORAGE D’ÉMULSION INVERSE ET PROCÉDÉ POUR RÉDUIRE LA TOXICITÉ DE CEUX-CI
Abstract: front page image
(EN)A method for reducing the toxicity of an invert emulsion wellbore fluid is disclosed. The method comprises forming an invert emulsion wellbore fluid comprising an oleaginous continuous phase, an aqueous discontinuous phase, and an emulsifying fluid, wherein the emulsifying fluid comprises a nitrogen-containing emulsifying agent and an alkalinity agent, and wherein the invert emulsion wellbore fluid produces an LC50 (SSP) of at least 30.000 parts per million at 3000°F.
(FR)La présente invention concerne un procédé pour réduire la toxicité d’un fluide de puits de forage d’émulsion inverse. Le procédé comprend la formation d’un fluide de puits de forage d’émulsion inverse comprenant une phase continue oléagineuse, une phase discontinue aqueuse, et un fluide émulsifiant, le fluide émulsifiant comprenant un agent émulsifiant contenant de l’azote et un agent d’alcalinité, et le fluide de puits de forage d’émulsion inverse produisant une CL50 (SSP) d’au moins 30 000 parties par million à 3000 °F.
