ABSTRACT:
A method for sealing an annulus defined between an outer casing and an inner casing, the method having steps as follows: fastening a lock ring to an anchor base, wherein the lock ring comprises a threaded fastener of the lock ring to the head; positioning the lock ring and anchor base about the outer casing; fastening a limit clamp to an exterior surface of the outer casing; repositioning the lock ring and anchor base so that the anchor base is in contact with the limit clamp; fastening a head to the lock ring; providing an opening for fluid communication with the annulus through the head; positioning a plug about the inner casing and in contact with the inner casing and the head; positioning a seal fitting clamp about the inner casing and in contact with the plug; positioning a bull cap about the inner casing and in contact with the seal fitting clamp; and fastening the bull cap to the head.
