Offshore Mozambique: Anadarko suspends drilling on Collier 1 because of safety concerns, may re-enter

Source: Cove Energy

Cove Energy has been informed by Anadarko Petroleum Corporation, operator of the Rovuma Area 1 offshore block Mozambique (Cove 10% paying interest, 8.5% net), that it has ceased drilling operations on the Collier 1 well, having encountered pore pressure issues at the top of the predicted reservoir objective, causing the operator to deem it unsafe to continue drilling.

The Collier 1 well did not penetrate or fully evaluate the entire predicted objective section. For these reasons the Area 1 Offshore partners have agreed to suspend the Collier 1 well in a manner which would allow re-entry of the well bore at a later date pending analysis of all relevant well data.

The Belford Dolphin deepwater drillship continues drilling in Area 1 Offshore commencing with the Ironclad Palaeocene/Cretaceous prospect in the southern part of the 3D seismic area, to be immediately followed by the drilling of the Barquentine well which will test an independent prospect near the Windjammer discovery well. The current plan is for the rig to set surface casing on Barquentine, and then drill Ironclad before returning immediately to finish Barquentine. A map showing the location of these prospects can be found on the Cove company website.

"Whilst it is regrettable that the target objectives at Collier have not yet been fully evaluated, safety is the top priority and we have to go with the recommendation of the operator in such circumstances,” said John Craven, CEO of Cove Energy. "In the meantime the drilling program advances to drill two exciting prospects, Ironclad in the south followed by Barquentine in the north, near the Windjammer discovery. At the same time evaluation of the Collier well data will continue."
