Carnarvon Petroleum Ltd has provided the following update on drilling operations as advised by the operator of the Roc-1 well, Quadrant Energy.
Since the last report the 244 mm (9 5/8”) casing has been set and cemented in place and drilling of the 216 mm (8 1/2”) hole has commenced slightly ahead of prognosis.
As at 06:00 hours on 14 December 2015 the well was drilling ahead in the 216 mm (8 1/2”) hole final section at a depth of 3435 m.
It is expected to take up two weeks to drill through the final section from 3400 m to the anticipated total depth of around 4750 m. In a success case wireline logging will take a further five days to be obtained.
The operator has also proposed a contingent intermediate logging run at a depth of around 4000 m to de-risk data acquisition after drilling through the top reservoir of 3750 m in the approximate hole section equivalent to where oil was discovered in the Phoenix South-1 well. The decision to run this intermediate suite of logs will depend on hole condition and results to date.
The Roc-1 well is located in WA-437-P, approximately 20 km south-east of the 2014 Phoenix South-1 oil discovery, and around 150 km north of Port Hedland.
