On the optimization of acid compositions for geotechnical conditions of oilfields of Bashneft JSOC

Authors: A.E. Folomeev, A.S. Vakhrushev , A.G. Mikhaylov (BashNIPIneft LLC, RF, Ufa)
Key words: bottomhole treatment, acid composition, colmatation, self-diverting acid composition.

Two ways of improving the acid stimulation are considered: optimization of acid composition to prevent the risks of mudding during the treatments; study of new technologies with the increased depth of penetration of theacid composition in the bottomhole formation zone and the coverage of not only high- , but low-permeability interlayers. The optimal concentrations of the acid compositions modifiers are sel ected taking into account geological and technical conditions of Bashneft-Dobycha LLC field development. The most effective additives are established and recommended for experimental field tests.
