FIELD: method for production of biosolutions from bitumen foam tail.
SUBSTANCE: bitumen foam tails containing carbohydrate metabolizing natural microorganisms are mixed with broth to provide an inoculate followed by incubation under isothermal conditions for such period of time as to obtain mixed bacterial culture, containing biosolution and water with limited amount of asphaltenes, as well as solids such as clay and sand. Obtained biosolution further is used in starting process of bitumen sand conditioning to provide bitumen foam, as well as in bitumen sand recovery by direct solution injection into bitumen sand formation. Biosolution also is used for asphaltene decomposition. Method of present invention makes it possible to obtain bitumen foam at lower temperature without application of caustic soda and avoid bitumen foam tail formation cased by clay dispersion.
EFFECT: decreased waste quantity in process of bitumen extraction.
