ALL eyes are on the progress of the Roc-2 appraisal well as it closes in on its primary target off the north west coast of Western Australia.

Located approximately five km from the Roc-1 gas and condensate discovery completed by Quadrant Energy and Carnarvon Petroleum earlier this year, Roc-2 is aimed at proving up the minimum commercial development level for the Roc structure.

A commercial find will also open up a new, near shore play opportunity in WA waters.

At last reports Roc-2, which is being drilled by Diamond Offshore’s Ocean Monarch semisubmesible rig, had been drilled to 4,057metres measured depth, and was being prepareed to drill through the Hove section and then into its primary Caley member target before continuing on to a planned total depth of around 5,250 metres.

The well has already encountered encouraging gas and fluorescence readings at higher levels and the Quadrant and Carnarvon JV have indicated they may undertake flow testing if potentially commercial levels of hydrocarbons are intersected.

The Roc-2 well is located on the other side of the Roc structure from Roc-1 which encountered a gross reservoir section of around 120 m in the Caley, with the top 40 m being hydrocarbon bearing.

Located within exploration permit WA-437-P in the North West Shelf and approximately 160 km north-east of Port Hedland, Roc-2 is being drilled in around 100m water depth.
