Beschreibung
Zusammenfassung:	oil and gas production. SUBSTANCE: invention, in particular, relates to compositions for increasing oil recovery in formation in late development stage. Composition contains, wt %: excessive activated sludge as microorganism source, 1.0-2.0; bottom residues from synthetic glycerol production as nutritive medium, 0.5-2.0; polymeric dimethyldiallylammonium chloride (additionally), 0.02-0.10; and water from secondary settlers at biological waste disposal plants, the balance. EFFECT: improved filtration ability of composition and increased gas emission. 4 tbl
