Key words: oil reservoir, productivity factor, well, acid fracturing, bottomhole pressure.
The authors consider changing of well production and productivity factor after the acid fracturing in the Gagarinskoye and Ozernoye oilfields. It is shown that pressure decrease greatly reduces the technological effect of bottomhole acid fracturing. Acid fracturing operation should be conducted with maximum face pressure reduction taking into account the effects of gas and reservoir strain on the producing wells productivity.
