Abstract:
A process for sealing casing leaks comprises cleaning out the annulus between the tubing and the casing, situating a gelable mixture in the annulus at the loci of the leak in the casing, pressuring the mixture through the leak into the formation and effecting gelation of the mixture. Optionally, the remaining gelable mixture may be circulated out of the annulus. Gelable mixtures can be comprised of various organic and inorganic gel polymers.
