Carnarvon Petroleum Limited says that a new sidetrack wellbore section of the Phoenix South-1 well is required to be drilled below the 13 3/8' casing depth, due to the 9 5/8' casing hanger seal assembly running tool (CHSART) ('casing tool'), becoming stuck and preventing forward drilling progress of the current wellbore.

Earlier on 13 June 2014, the Phoenix South-1 well had drilled to 3,706 m depth and was in the process of setting the 9 5/8' diameter casing to support the hole, as per standard industry practice. After setting and cementing the casing in place, the casing tool was unable to be retrieved from the wellhead.
