Quadrant Energy has commenced drilling of the Roc-2 well, offshore Western Australia, said partner Carnarvon Petroleum.
The main aims of the Roc-2 well are to appraise the Roc gas-condensate discovery in the Caley section. The information will be used to progress towards proving a volume above the minimum economic field size and to establish potential flow rates for future development planning.
Secondary objectives for the well are to explore the hydrocarbon potential of the deeper Milne member, where 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 100m water depth, approximately 160km northeast 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 5250m, including the cutting of 120m of core, before the evaluation program 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. Quandrant Energy (80%) is the operator, with partner Carnarvon Petroleum (20%).
