METHOD OF SEALING WELLS BY INJECTION OF SEALANT

A method for sealing a well includes: placing an obstruction in a bore of an inner tubular string; forming an opening through a wall of the inner tubular string above the obstruction; mixing a resin and a hardener to form a sealant having a density greater than a density of fluid present in the bore...

description A method for sealing a well includes: placing an obstruction in a bore of an inner tubular string; forming an opening through a wall of the inner tubular string above the obstruction; mixing a resin and a hardener to form a sealant having a density greater than a density of fluid present in the bore and present in an annulus formed between the inner tubular string and an outer tubular string; and injecting the sealant into the annulus. The sealant falls down the annulus to the opening. A portion of the sealant is diverted through the opening and into the bore. The sealant cures to form a balanced plug in the annulus and the bore.
