  • Method to attain full annular coverage during cementing or mud circulation
    Patent number: 11286726
    Abstract: Methods and systems are directed to the uniform distribution of a fluid through an annulus between a pipe and a wellbore wall, primarily when there is a preferential flow in one side of the annulus relative to another side of the annulus. Generally, the methods and systems involve introducing a first agent into the annulus, wherein the first agent is configured to cause swelling of a cladding on the exterior of the section of the pipe. The swelling reduces flow in the annulus on the side of the pipe with preferential flow so as to reduce the preferential flow on that side of the pipe.
    Type: Grant
