Deep, HPHT well in GOM plugged and abandoned using coiled tubing
Coiled tubing (CT) was used, for the first time, to clean out a Gulf of Mexico (GOM) well to 22,610 ft and successfully place a bottom cement plug. The job was completed in 27 days at a lower cost than if a conventional rig was used. Challenges included bottomhole static temperature (BHST) greater than 400°F and the presence of H2S with a concentration of 75 ppm and 4% CO2.
