REAGENT FOR INCREASING OF FORMATION OIL RECOVERY Russian patent published in 2002 - IPC

Abstract RU 2178519 C1

FIELD: oil producing industry; applicable in increasing of oil recovery from formation in their waterflooding. SUBSTANCE: reagent is recommended to be used in the form of oxyethylated carbonic acids with general formula C_nH_2n+1COO(C₂H₄O)_mH, where n= 15-20; m= 2-11 with molecular weight of 344-810. Reagent is more stable and therefore more effective in mineralized media and more liable to biological decomposition. EFFECT: extended range of efficient reagents stable in heavily mineralized waters for increasing of formation oil recovery with higher ecological efficiency in formation development. 3 tbl
