摘要： A method for abandonment of a subsea well includes: setting a packer of a lower cementing tool against a bore of an inner casing hung from a subsea wellhead; fastening a pressure control assembly (PCA) to the subsea wellhead; hanging an upper cementing tool from the PCA and stabbing the upper cementing tool into a polished bore receptacle of the lower cementing tool; perforating a wall of the inner casing below the packer; perforating the inner casing wall above the packer by operating a perforator of the upper cementing tool; mixing a resin and a hardener to form a sealant; and pumping a fluid train through bores of the cementing tools and into an inner annulus formed between the inner casing and an outer casing hung from the subsea wellhead. The fluid train includes the sealant followed by a cement slurry.

摘要： A method for sealing a well includes: placing an obstruction in a bore of an inner tubular string disposed in a wellbore; forming an opening through a wall of the inner tubular string above the obstruction; mixing a resin and a hardener to form a sealant; and squeezing the sealant into the bore, through the opening, and into an annulus formed between the inner tubular string and an outer tubular string, thereby repairing a cement sheath present in the annulus.
