Roc-2 well commences drilling

Carnarvon Petroleum Limited (Carnarvon) (ASX:CVN) has reported that the operator of the Roc-2 well, Quadrant Energy, has advised that the well commenced drilling on 9 July 2016.

The main objectives of the Roc-2 well are to appraise the Roc gas-condensate discovery in the Caley section that Carnarvon announced on 4 January 2016,  in order to advance towards proving a volume above the minimum economic field size and to establish potential flow rates for future development planning.

Exploring hydrocarbon potential

Secondary aims for the well are to explore the hydrocarbon potential of the deeper Milne member, in which encouraging hydrocarbon shows were observed during the final phase of drilling the Roc-1 well, and the shallower Huxley member, where oil shows were encountered at Roc-1.

The Roc-2 well will be drilled in around 100 m water depth, approximately 160 km north-east of Port Hedland in the Bedout sub-basin of the greater Roebuck basin. The well will take approximately 60 days to drill down to a total depth of around 5250 m, including the cutting of 120 m of core, before the evaluation programme is undertaken. The evaluation, including wireline logging and flow testing, is expected to extend over a further 40 days.

The Roc prospective and contingent resources are within the WA-437-P exploration permit in the North West Shelf of Australia. The equity interest holders are:

Carnarvon Petroleum 20%

Quadrant Energy (Operator) 80%
