Gas Found at Bianchi-1 Well in Carnarvon Basin

Tap Oil Limited provided the following update of the Bianchi-1 gas appraisal well in Retention Lease WA-49-R off Western Australia. The well is targeting sandstones in a Triassic age Mungaroo Formation within a separate fault block down dip of the Zola-1/ST1 gas discovery.

Location and Proposed Depth

The Bianchi prospect is located in the WA-49-R retention lease in the offshore Carnarvon Basin, approximately 4 miles (6.4 kilometers) north-northeast of the Zola-1/ST1 gas discovery and 12.9 miles (20.8 kilometers) south-southwest of the Gorgon-1 gas discovery well.

The Bianchi fault block is one of a series of adjacent structures that form the greater Zola area. The prospect was matured following interpretation of the Cambozola 3D seismic survey in 2012.


During the period from 0600 hours (AWST) July 2 to 0600 hours (AWST) July 9 wire line logging operations were undertaken. The logging program was interrupted in order to conduct rig repairs which have been now been completed. The wireline logs acquired prior to the interruption of logging confirm a gas discovery, with gas gradients established and gas samples recovered in the upper sands of the potential gas bearing interval interpreted from the data acquired to date (LWD) data. Further analysis is required on the lower section of the potential gas bearing interval.

Forward Plan

The Joint Venture has agreed to drill an additional 328 feet (100 meters) of section beneath the current total depth (TD). After reaching the final TD 17,979 feet (5,480 meters) the wireline logging program will resume to finalize the evaluation of the well.
