Title: METHOD FOR ENHANCING METAL CORROSION INHIBITION IN OIL AND NATURAL GAS PRODUCTION
Abstract:
The instant invention relates to the use of synthetic polymer in combination with an organic corrosion inhibiting compound having at least one unsaturated carbon-carbon bond, preferably selected from the group of acetylenic alcohols, α,β-unsaturated aldehydes, and/or α-alkenyl phenones, reducing or inhibiting corrosion of metal equipment being present during acidizing treatment in gas- or oilfield reservoirs with one or more acids. A further aspect of the invention is a method for reducing or inhibiting corrosion of steel equipment being present during an acid treatment of a gas- or oilfield reservoir with one or more acids by using a specific synthetic polymer as corrosion inhibitor in combination with an organic corrosion inhibiting compound having at least one unsaturated carbon-carbon bond, preferably selected from the group of acetylenic alcohols, α,β-unsaturated aldehydes, and/or α-alkenyl phenones.
