摘要： A method for the fracking or stimulation of a hydrocarbon-bearing formation, said method comprising the steps of: providing a wellbore in need of stimulation; inserting a plug in the wellbore at a predetermined location; inserting a perforating tool and a spearhead or breakdown acid into the wellbore; 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 fracking or stimulation; removing the tool from the wellbore; and initiating the fracking of the perforated area using a fracking fluid. Also disclosed is a corrosion inhibiting composition for use with the acid composition.

摘要： A method for the stimulation of a hydrocarbon-bearing formation, said method comprising the steps of providing a wellbore in need of stimulation; inserting a plug in the wellbore at a location slightly beyond a predetermined location; inserting a perforating tool having an outside surface and a spearhead or breakdown acid composition into the wellbore, wherein said outside surface of said tool is pre-treated prior to downhole insertion with a grease containing a first corrosion inhibitor adapted to eliminate/minimize/reduce the corrosion inflicted upon it by the exposure of the acid for the duration of the fracking or stimulation and wherein said acidic composition comprises a second corrosion inhibitor which reacts with said first corrosion inhibitor to generate a corrosion protective layer onto said surface; 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 from the wellbore; and initiating the fracking of the perforated area using a stimulation fluid. Also disclosed is a corrosion inhibiting compound or composition for use with the acid composition.

摘要： A novel method for the placement of spearhead acid and stimulation of a hydrocarbon-bearing formation, said method comprising the steps of 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.
