A method for unloading fluids from an oil and gas well, pipeline or flowline includes using a synergistic combination of an alkyl glucoside and an amphoteric surfactant as a foaming composition. Use of the combination foaming composition improves unloading of formation fluids, particularly production fluids having natural gas condensate and water and therefore increases the rate of production from the oil and gas well.
La présente invention concerne un procédé de décharge de fluides provenant d'un puits de pétrole et de gaz, d'un pipeline ou d'une conduite d'écoulement qui comprend l'utilisation d'une combinaison synergique d'un alkylglucoside et d'un agent tensioactif amphotère en tant que composition moussante. L'utilisation de la combinaison de composition moussante améliore la décharge des fluides de formation, en particulier les fluides de production contenant un condensat de gaz naturel et de l'eau et augmente donc le taux de production du puits de pétrole et de gaz.
