摘要： A process for producing mineral oil from mineral oil deposits by injecting aqueous flooding media into a mineral oil formation through injection boreholes and withdrawing the mineral oil through production boreholes, wherein the process comprises several cycles of process steps in which oil-mobilizing microorganisms and flooding water are injected alternately into the deposit. Processes in which highly permeable regions of the mineral oil formation are additionally blocked.

摘要： A two-stage process for mineral oil production from mineral oil deposits with a deposit temperature of more than 70° C. and a salinity of 20 000 ppm to 350 000 ppm, in which an aqueous formulation comprising at least one glucan with a β-1,3-glycosidically linked main chain, and side groups β-1,6-glycosidically bonded thereto and having a weight-average molecular weight Mw of 1.5*106 to 25*106 g/mol, are injected into a mineral oil deposit through at least one injection borehole and crude oil is withdrawn from the deposit through at least one production borehole. The aqueous formulation is prepared in two stages, by first preparing an aqueous concentrate of the glucan, and diluting the concentrate on site with water to the use concentration.

摘要： A process for the preparation of aqueous solutions of glucans having a β-1,3-glycosidically-linked main chain and side groups having a β-1,6-glycosidic bond by fermentation of fungal strains. The fungal strains secrete the glucans into the fermentation broth, in an aqueous culture medium, and the separation of the glucans from the fermentation broth is effected using asymmetrical filter membranes.
