Solutions of dithiocarbamate salts, such as the sodium salts of N-methyl dithiocarbamate and N,N-dimethyl dithiocarbamate, can be utilized as admixtures with acids, to provide admixtures that are non-corrosive to mild steels in the treatment of oil production systems. Some admixtures are even corrosion inhibiting. Both general corrosion and pitting corrosion forms are affected by the dithiocarbamate admixtures. As a consequence, petroleum production is facilitated as evidenced by the lowering of pour points, the reduction of pressures in flow lines, the reduction of separation problems, and increased crude oil yields.
