  • METHOD TO REPAIR LEAKS IN A CEMENTED ANNULUS
    Publication number: 20140262269
    Abstract: A method of providing pressure containment of a well having a well annulus. The well annulus contains a set cement, and the cement contains flow paths which communicate a well pressure to the surface. The method includes placing a containment cement slurry in a reception area at the top of the well and installing an injection delivery system within the reception area. The method may further include preparing a settable fluid for injection into the flow paths and injecting the settable fluid through the injection delivery system into the flow paths. In one disclosed embodiment, the injection delivery system may include a series of injection tubulars configured to deliver the settable fluid to the flow paths. The injection delivery system may include a template having a first, second, third and fourth injection tubular.
