This article discusses the use of sealants to control fluid losses while drilling through fault zones in an offshore oil well. According to the authors, the use of wellbore pressure containment integrity treatments can increase pressure of leak off tests and allow drilling to greater depths. They describe the challenges found in drilling the western continental shelf in the Gulf of Mexico offshore Louisiana including high pressure and high temperature conditions, depleted reservoirs, abnormal pressure ramps and lost circulation. They review treatment design procedures and conclude that the treatment was successful.
