  • Process for stimulating petroleum production wells
    Patent number: 4595511
    Abstract: Process for stimulating petroleum production wells by injecting, into the production well, a solution of higher aromatics (high-flash aromatics) which contains a mixture comprising 50-90% of an oxyalkylated C.sub.12 -C.sub.22 -mono- or -di-alkylamine or alkenylamine and 10 to 50% of a petroleum emulsion-breaker. In addition, the solution can also contain oxyalkylated alkylphenols, fatty acids and glycol ethers. This stimulation method produces an excellent influx of oil, a very high oil table and hence a significantly raised rate of production.
