Developed is SNPX (DN)-9010 composition for increasing oil reserves recovery efficiency in low-productivity carbonate reservoirs, which has been successfully applied in oil producing company "Arlanneft" for oil production stimulation. Presented are the results of such composition application in abovementioned oil producing company. It is shown, that efficiency of sulfuric acid stimulation at the late stage of development is extremely low, but stimulation by SNPX (DN)9010 composition provides for acceptable daily rates.
