The Duntroon Basin is located in the centre of the Southern Rift System between the Bight and the Otway Basins, west and SW of Kangaroo Island. It is limited to the north by the Proterozoic Gawler Craton. The formation of the basin is related to the...

Sedimentation in the Great Australian Bight (GAB) has occurred in a variety of settings from the initial intra-cratonic rift to the modern carbonate shelf. An extensive palaeodrainage system, remnants of which are still preserved, supplied clastic...

The offshore Mesozoic-Tertiary Bight and Duntroon basins formed through rifting and separation of the Australian and Antartic plates. Palynological investigation of samples dredged during BMR Rig Seismic Cruise 66 showed that the bulk of the...

This EPP 26 surrender report has been furnished to the SA offshore Designated Authority as a result of the application made on 21/8/96 by BHP Petroleum for permission for the joint venture to surrender the permit, before committing to unwanted...

A complete re-evaluation of all known prospects and leads within EPP 21 was undertaken by the permittees in order to define any prospects worthy of drilling in permit Year 4, ending 28 June 1986, by which time a commitment to drill one well and...

This frontier basin lithostratigraphic and biostratigraphic correlation study is largely based on the petrographic examination of 104 thin sections of samples from rocks intersected in the three Shell offshore exploration wells drilled on the northern...

The R 10 Marine Seismic Survey was conducted during March, 1976 within EPPs 10 and 11 to detail the previously indicated Galah, Kookaburra and Rosella-Jabiru leads. This survey defined three structurally sound closures, Galah, Kookaburra East and...

EPPs 10 and 11 currently comprise 239 graticular blocks (approximately 17 000 sq km) in the Great Australian Bight Basin. No wells have yet been drilled in these permits which lie entirely in water depths greater than 200 m and ranging down to 1 500...

Three structural closures have been defined by the R 10 survey. These are Galah in Permit SA-11 and Kookaburra West and Kookaburra East in Permit SA-10. Economic evaluation of the structures is currently being undertaken, but it is considered in the...

Contains summary pictorial montages of the operator's post-mortem assessment of the value of drilling each Duntroon Basin wildcat completed to date.

AIM: To confirm a number of prospects and leads outlined with the most recent interpretation of the existing seismic data over both permit areas. Due to the presence of shallow intrusives and difficulty in mapping the basement in certain areas,...

Contains the operator's pre-drill prospect evaluation file, the drilling contractor's FMS (Formation Micro Scanner) dipmeter log interpretation report and summary plots, and the well seismic processing (VSP velocity survey) report and GEOGRAM plots.

BHPP's Greenly 1 well is herein proposed to test a faulted hanging wall anticline with minor crestal collapse faults, an estimated fault-dependent maximum closure area of 53.3 square km, and a closure height of 140 metres at the primary target. The...

AIM: The DH91 seismic survey programme was designed to provide new 2D coverage of potential prospects and leads in an offshore area with very little modern seismic data, especially in the southeastern part of the permit. Complementary 1983 and 1984...

Report gives an analysis of the Schlumberger FMS (Formation Micro Scanner) well log data obtained from Borda 1, as part of a study of dipmeter logs derived from each of the three BHP Petroleum wells in the basin. The aim is to determine regional...

Contains the well logging contractor's FMS (Formation Micro Scanner) dipmeter log interpretation report and summary plots.

BHPP's Borda 1 well is herein proposed to test a faulted four-way dip closure in permit EPP 25 with an estimated fault dependent closure area of 26.2 square kilometres and height of 125 metres. The trap formed during the Late Eocene to Early...
