Abstract: An acid soluble copper metal salt intensifier is provided for a fluid for treatment of a subterranean well for enhancement of production within the well by introduction of the fluid through a high alloy steel member positioned within the well. The treatment fluid comprises an acidic injection medium and an acid corrosion inhibitor. The intensifier is introduced into the fluid for deposition on or effective treatment contact with the high alloy steel. A method of inhibiting acidic corrosion and a method of treating a subterranean well for enhanced production also are disclosed.
