Eight samples of unwashed cuttings from 1500-3510 metres (Aptian to late Eocene) were measured to determine thermal history. A major jump in the apatite grain age profile between the Tertiary and Cretaceous is attributed to a major shift in sediment...

Contains interpretation reports on satellite imagery remote sensing and reprocessed aeromagnetic data, plus other brief interpretative statements by the contract operator contained within some quarterly tenement reports.

Denman Seismic Survey - AIM: This seismic survey of 4 lines totalling 40.0 line kms coverage was conducted in the southern Denman Trough, in the vicinity of Outback Oil's Denman 1 well drilled in 1966, in order to fulfil the Licence Year 2 work...

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,...

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...

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...

Four wells, drilled within 36 km of the Hughes and Denman Railway Sidings, explored for a possible Palaeozoic section and/or Upper Proterozoic or older basement, that was expected from Outback's regional gravity survey data to occur at or around...

Eyre 1 (total depth 1719 feet KB) and Gambanga 1 (TD 1283 feet KB) oil exploration wells, drilled in WA in the western part of the Eucla Basin, penetrated a succession of marine mainly Upper Eocene and Cretaceous rocks before entering crystalline...

Cook 1 well, drilled on the Nullarbor Plain to a total depth of 915 feet KB, intersected approximately 470 feet of Tertiary sediments followed by unfossiliferous sands, and then limestones and sands of possible Lower Cambrian age, in which drilling...

This report provides a brief summary of the geology and petroleum potential of the onshore, South Australian portion of the Eucla Basin at the time of termination of PEL 4, with the aim of providing a starting point for more thorough studies.

Maralinga is located on the crest of the Ooldea Range, an ancient (Tertiary) coastal dune which is bounded to the south by the Nullarbor Plain and to the north by Tietkens Plain. The dune field of the Great Victoria Desert covers much of the region...

The four stratigraphic wells completed in the Eucla Basin within 20 miles of the Hughes and Denman Railway Sidings intersected a sequence of Tertiary, Lower Cretaceous, probable Palaeozoic, and possibly some Proterozoic rocks. The ages of the...

Of the well's total depth of 1495 metres, the top 433 metres are fossiliferous, for which this report outlines the stratigraphy as determined from selected drill cores and cuttings. The biostratigraphy of the sequence studied in Mallabie 1 proves the...

The molluscan faunas of the Upper Eocene Wilson Bluff Limestone and Miocene Abrakurrie and Nullarbor Limestones are identified and figured. The brachiopods of the Wilson Bluff and Abrakurrie Limestones are identified.

Preliminary maps were compiled by photointerpretation with limited geological ground control. Some topographic features and photo - lineaments are considered structurally significant and may reflect faults with NE - ENE and NW orientations. The...

Stratigraphic evidence indicates major change in sedimentary regime in the Middle Eocene, close to the inferred onset of continental breakup. Deep sea drill core suggests an Antarctic ice sheet may have existed at this time, when Australasia was much...

Outcrop and subsurface samples taken from various sources, that represent all the Cainozoic marine formations of the eastern Eucla Basin, have been studied. The current stratigraphic knowledge of these formations in SA is summarised. A marine...
