Claim 11:
12. A method for treating a tubing-casing annulus, comprising:
coupling using the fluid conduit the treatment bladder containing the treatment fluid of the treatment system of claim 1 to the tubing-casing annulus of the wellhead system, where the lower fluid junction of the treatment bladder is positioned at an elevation higher than the tubing-casing annulus junction of the tubing-casing annulus of the wellhead system;
establishing two-way fluid communication between the tubing-casing annulus using the tubing-casing annulus junction of the wellhead system and the treatment bladder though the fluid conduit;
halting fluid communication though the fluid conduit between the tubing-casing annulus and the treatment bladder; and
decoupling the treatment bladder from the tubing-casing annulus.
