The well was drilled in 2012 to a depth of 2635m AH and was found dry. The 13-3/8” and 9-5/8” casing-shoes were set at 564m and 1295m respectively. The well was permanently abandoned by means of 5 cement plugs. The 9-5/8” production casing was cut and retrieved from 600m creating a uncased hole section of 40m between the top of the 9-5/8” and the shoe of the 13-3/8”. Cement plug #4 was set in this open hole section. After removal of the wellhead and demobilization of the rig gas bubbles were detected. As a result an emergency slip-lock head MX2 wellhead and a 4-1/16” X-mass tree were installed.
The objective was to re-enter the well, find the leak and re-abandon the well.
