This paper presents the results of applying the two acid solutions for stimulation of oil wells in the Bashkir sediment rocks in the fields of Perm region. The influence of technological and geo-physical parameters of the layers on the success of the acid treatments is estimated by comparing the rates of well productivity before and after acid treatment. It is observed that after the acid treatment, water content in well products increases in the majority of cases. With the growing volume of acid solution pumped per unit of effective oil acid, performance impact is increasing. The average depth of penetration of the acid solution in the bottom zone of 0.5 m. Overall it was obtained that conducted acid treatment stimulation of the oil wells was effective and provided the lasting effects on the well productivity. The rate of success is higher for the wells with low reservoir pressure.
