In situ decomposition of carbonyls at high temperature for fixing incomplete and failed well seals |
摘要 |
Methods and systems relating to in situ decomposition of carbonyls at high temperature for fixing incomplete and failed well seals, are described. According to one embodiment, a method, comprises injecting a sealing agent into a subterranean well having sealing channels or voids in well casings. An alkaline-earth carbonate precipitate is formed from the decomposition of a carbonyl compound. The sealing agent includes the carbonyl compound and an alkaline-earth halide salt.
