Methods for stimulating a hydrocarbon-bearing formation by perforating a wellbore and introducing an acidic composition in the wellbore

A method for the stimulation of a hydrocarbon-bearing formation within a wellbore, said method comprising:

• inserting a wireline and a bottom hole assembly comprising a plug and a perforation tool into said wellbore, wherein said bottom hole assembly is connected to a wireline;
• injecting an acidic composition into the wellbore, wherein said acidic composition is in direct contact with both said wireline and casing;
• perforating the wellbore with the perforation tool thereby creating a perforated area;
• causing the acidic composition to come into contact with the perforated area for a predetermined period of time to prepare the formation for fracking or stimulation;
• and
• wherein the acid composition comprises a corrosion inhibitor package comprising at least two compounds selected from:
• Group B;
• Group C;
• Group D;
• Group E, where the at least two compounds are selected from different groups and where:
• Group B comprises compounds encompassed within the following general chemical description:
• acetylenic compound;
• unsaturated alcohol;
• acetylinic alcohol;
• alkoxylated acetylenic alcohol;
• alkoxy phenols;
• diacetylenic alcohols;
• Group C comprises compounds encompassed within the following general chemical description:
• a group 15 metal including bismuth,
• antimony;
• antimony compounds;
• germanium compounds;
• Group D comprises compounds encompassed within the following general chemical description:
• sulfur-containing compounds;
• mercapto-compounds;
• organosulfur compounds reaction products of thiourea;
• thiodiglycol alkoxylates;
• Group E comprises compounds encompassed within the following general chemical description:
• nitrogen-containing surfactant;
• and
• non-ionic surfactant.
