Abstract
A method for stimulation of a hydrocarbon-bearing formation includes inserting a perforating tool and an acidic composition into a wellbore. An outside surface of the tool is pre-treated prior to downhole insertion with a grease containing a first corrosion inhibitor adapted minimize corrosion by exposure of the tool the acidic composition for a duration of the stimulation process. The acidic composition further comprises a second corrosion inhibitor that reacts with the first corrosion inhibitor to generate a corrosion protective layer onto the outside surface of the tool. The method further includes perforating the wellbore with the tool, allowing the acidic composition to come into contact with the perforated area of the wellbore, removing the tool from the wellbore; and initiating the stimulation of the perforated area using a stimulation fluid.
