Substantiation and development of acid deflector compositions based on water-in-oil emulsions to improvement of the effectiveness of the bottom-hole treatment

Authors: A.R. Mavliev, M.A. Almukhametov, I.A. Petrov, A.S. Shishlov, V.R. Fetisova (Muravlenkovskneft Branch of Gazpromneft-Noyabrskneftegas OJSC, RF, Muravlenko), M.K. Rogachev (National Mineral Resources University, RF, Saint-Petersburg)

Key words: acid compositions, emulsion sistems, polimict reservoirs, bottomhole zone, adhesion, dispersability.

It is necessary to consider a complex approach for acid treatment of injection wells characterized by polymict sandstone reservoir with high layered heterogeneity. This approach takes into account variety of factors affected on total effectiveness. The paper represents recommendations for blend composition regulation of acids and emulsions oriented on field experience of acidizing and laboratory tests. Also the paper demonstrates comparison of standard acid treatment carried out in Muravlenkovskneft and acid deflector-technology.
