The Apache-operated Bianchi-1 well, in the WA-49-R retention lease in the offshore Carnarvon Basin, Australia, today reached a final total depth of 5,380 metres and wire line logging
According to Tap Oil, which owns a 10% share in the project, from 4,777 metres to the total depth, the data acquired to date (LWD logs) indicates several sandstone intervals with elevated resistivity interpreted by Tap to be potential gas pay. Tap interpretation of this preliminary data indicates some 128 metres of potential net gas pay in the well.
“A comprehensive wire line logging program to evaluate the well is in progress to confirm the preliminary interpretation of the LWD data,” said Tap in a statement.
The Bianchi-1 gas appraisal well is located, approximately 6.4km north-northeast of the Zola-1/ST1 gas discovery and 20.8km south-southwest of the Gorgon-1 gas discovery well.
The well is being drilled to provide additional information on the potential development path for the permit, including the Zola discovery.
Participants in the project are as follows: Apache Northwest Pty Ltd (Operator) 30.25%; Santos Offshore Pty Ltd 24.75%; OMV Australia Pty Ltd 20.00%; JX Nippon Oil and Gas Exploration (Australia) Pty Ltd 15.00%; Tap (Shelfal) Pty Ltd 10.00%
