After laboratory research the pilot treatment has been done. After obtaining positive results from this treatment, BMB oil field operator begun to use emulsified acid for small scale acidizing treatment on production wells. Six acidizing treatments have been performed using emulsified acid. Oil and gas production increase was achieved after each treatment. Significant oil and gas production increase and decrease of near wellbore pressure drop was noticed during the production process.

After positive results of emulsified acid treatment have been achieved on BMB oil field, this technology was successfully introduced in wells on another oil field located on the same carbonate formation
