Results of mud acid treatments at fields of Octyabrskoye oil and gas production department are analysed. Dependence of an additional oil recovery after these treatments on the saturation pressure - bottom-hole pressure ratio is given. The technology of gipan-thermoacid treatment of the flooded well is developed. The mechanism of thermoacid action on flooded reservoirs is considered.
