Abstract
A method of replacing a corroded well conductor positioned in an oil production platform at an offshore location. After shutting in or killing the well, the wellhead is removed and the sections of the casing and tubing strings within the well conductor above the mud line are backed off and removed. The damaged well conductor is cut off above the mud line leaving a stub to which the lower end of a new section of well conductor is connected and bonded by means of a novel connector. Communication between the old and new sections of well conductor is established and the casing and tubing sections are re-installed in the new well conductor and the wellhead is closed.
