Casing and Tubing Leak Sealant Services

Seal-Tite provides sealant services for leaks in the packers, sleeves and connections in casing and tubing. The delivery method depends on the nature and location of the leak. The Seal-Tite service engineer can deliver our sealant to casing leaks both as a pill and atomized into natural gas or nitrogen. In tubing applications, Seal-Tite can dump bailed the sealant.

In Algeria, a gas injector well had tubing leaks at depths above the safety valve. Injection pressure was 5050 psi. After bleeding off pressure from the P1 annulus, the pressure would increase at a rate of 150 to 200 psi per hour through the tubing leak. During the Seal-Tite operation, the leak path was established by injecting gas and venting the P1 annulus. While injecting gas, Seal-Tite sealant was atomized into the gas stream. A differential pressure was created from the tubing to the P1 annulus and the sealant was carried through the leak path with the injection gas. The sealant polymerized in the leak path and sealed the leak. At the conclusion of the sealant operation, the P1 annulus was shut-in. The shut-in P1 pressure stabilized to 35 psi.
