Abstract

MéTODO PARA REDUZIR O TEOR DE áGUA DE FLUIDOS à BASE DE óLEO. Um método para reduzir o teor aquoso de fluido de perfuração baseado em óleo que inclui contatar um fluido de furo de poço de emulsão inversa com um polímero de absorção de água, interagir o polimero de absorção de água com o fluido de furo de poço por um período de tempo suficiente de modo que o polímero de absorção de água absorva pelo menos uma porção do fluido aquoso a partir do fluido de furo de poço; e separar o polímero de absorção de água contendo a água absorvida do fluido de furo de poço.METHOD FOR REDUCING THE WATER CONTENT OF OIL BASED FLUIDS. A method for reducing the aqueous content of oil-based drilling fluid including contacting a reverse emulsion wellbore fluid with a water absorbing polymer, interacting the water absorption polymer with the wellbore fluid by a sufficient time for the water-absorbing polymer to absorb at least a portion of the aqueous fluid from the wellbore fluid; and separating the water-absorbing polymer containing the absorbed water from the wellbore fluid.
