DDKG-2 faces problems at MA well

Vol 20, PW 4 (03 Nov 16) News in Brief

Unexpected technical trouble has hit Transocean deepwater drillship DDKG-2 as it prepares to workover a well at Reliance's MA oilfield in the KG-DWN-98/3 or KG-D6 licence.

DDKG-2 reached location KG D6-MA2-ST in water depths of 1250 metres on October 7. After the Blow out Preventor (BoP) was latched onto the wellhead, Transocean tried to pull out the well plug to begin the workover but was unsuccessful.

"The Lower Marine Riser Puller above the BoP to which the casing is attached got disconnected while the plug was being pulled out causing complications," we hear. Sources blame this on a failure of the rig's dynamic positioning system.

After the rig stabilised, Multipurpose Support Vessel Island Pride was deployed to remove debris from broken tubing and clean the wellhead. "This took a few days," says a source.

"Transocean is now trying to retrieve the plug." This sidetracked well is meant to be completed by December 15 after which DDKG-2 will move to offshore Myanmar for a four firm, four optional, one-year drilling assignment with Woodside Petroleum.
