Novel Downhole Methods And Compositions Used in Such |
| abstract |
A novel method for the placement of spearhead acid and stimulation of a hydrocarbon-bearing formation, said method comprising the steps ofn providing a wellbore in need of multiple stages of stimulation; inserting an isolation plug in the wellbore at a predetermined location; inserting a perforating tool and a spearhead or breakdown acid into the wellbore simultaneously exposing the wireline and tool to the acid; positioning the tool at said predetermined location; perforating the wellbore with the tool thereby creating a perforated area; allowing the spearhead acid to come into contact with the perforated area for a predetermined period of time sufficient to prepare the formation for stimulation; removing the tool form the wellbore; and initiating the stimulation of the perforated area using a stimulation fluid. Also disclosed is a corrosion inhibiting composition for us with the acid composition. |
