Technology Leaks may come from tubing, packer, casing, GLV, SSSV, CIV, etc. To cure those leaks, ERS or PGS sealants are spotted or squeezed into leak points. Sealants will penetrates into cement channelings and near bore formation fractures and stay there until it get crosslinks. After crosslinks, due to its excellent mechanical properties, unique high cohesive strength and bonding strength as well as plastic elastic features, it will permanent shut off near bore formation fractures, cement channels and leak point and build up a stress barrier within formation, cement isolation and permanent leak shut off. Application Over 3,000 jobs have been done all around the world. In PetroChina (CNP), multiple jobs have done to shut off casing corrosive leak, water zone, production zone, Casing collar thread leaks, control line leaks, fiber optic tube leaks, etc. Success rate is 100%. |
