Carnarvon Petroleum Ltd (ASX:CVN) has received an update on drilling operations by the operator of the Roc-2 well on Australia’s North West Shelf, Quadrant Energy.
Carnarvon holds a 20% interest, with Quadrant 80%.
The well has been designed to appraise and test the Roc-1 gas-condensate discovery revealed earlier in the year.
The Roc-2 appraisal well is required to delineate the extent of the Roc field, calibrate reservoir parameters, understand reservoir deliverability and characterise fluid properties.
Roc-2 will be drilled to a depth of 5,250 metres with capacity to extend to 5,700 metres if justified by hydrocarbon shows, reservoir quality and drilling conditions.
Progress
Since the last report the 26” (660 mm) hole has been drilled to around 1,275 metres measured depth and the 20” (510 mm) casing has been set and cemented in place.
Current Operations
The well has commenced drilling in the 17 ½” (445 mm).
Forward Plan
The rig is expected to take between 1 to 2 weeks to drill the 17 ½” (445 mm) hole down to a depth of around 3,500 metres measured depth before running the 13 5/8” (346 mm) intermediate casing.
No reservoir objectives are anticipated to be intersected in this hole section.
Roc-2 location and volumes
The Roc-2 well is located in 100 metres of water, around 160 kilometres north-east of Port Hedland in the Bedout sub-basin of the greater Roebuck basin.
Roc-1 encountered a gross reservoir section of around 120 metres in the Caley, with the top 40 meters being hydrocarbon bearing.
The Roc-2 well is designed to appraise this reservoir section in an updip location, around 5 kilometres to the east of the Roc-1 well.
