Abstract

A treatment system comprises a treatment bladder associated with a volume of a tubing-casing annulus of a wellhead system to be treated. The treatment bladder contains a treatment fluid and is at an elevated pressure. The treatment bladder is coupled to the tubing-casing annulus utilizing a fluid conduit through a lower fluid junction. The fluid conduit permits two-way fluid communication between the treatment bladder and the tubing-casing annulus. A method for treating the tubing-casing annulus includes coupling the treatment bladder containing the treatment fluid of the treatment system to the tubing-casing annulus of the wellhead system using the fluid conduit, establishing two-way fluid communication between the tubing-casing annulus and the treatment bladder though the fluid conduit, halting fluid communication though the fluid conduit, and decoupling the treatment bladder from the tubing-casing annulus.
