This review summarises Block exploration to date, provides a lengthy outline of the petroleum geology, and quantifies future hydrocarbon potential with respect to play concepts and mapped prospects and leads. Exploratory works comprising 49 wells,...

Field mapping of basement lithologies adjacent to, and of fluvial and marine sediments on the north-western margin of, the Eromanga Basin in the Abminga - Mount Irwin area, followed by a scout traverse of 18 stratigraphic core drillholes (total 1600...

A summary of Block petroleum prospectivity prepared prior to starting selective low-key exploration during the 1985-1989 licence period. The report gives the rationale for the proposed work programme of 4 wells and 1900 line km of seismic acquisition...

The Cooper Basin region has had a long structural history, reflected in differing structural styles ranging from thrust faults, to extensional horst and graben developments, to wrenching. The timing of this structuring in relation to the main period...

The structural contour map compiled in 1963 for the South Australian portion of the Great Artesian Basin has been revised with information available up to September, 1964. The Transition Beds and equivalents are used as the structural datum formation,...

The accompanying contour map was prepared by using a Cretaceous structural datum which covers most of the Great Artesian Basin in South Australia. The present edition of the map includes information available to January 1968 and represents a second...

As requested by Delhi Australian Petroleum Ltd, we have examined cuttings from Lake Frome No.1 and No.2 for microfossil remains. The wells are located in the Frome Embayment at Lat. 3 1 °03'25"S, Long. 1 39°51'52"E and Lat. 31°02'54.5"S , Long....

Dullingari 1 to a depth of 2798 metres has intersected a sedimentary sequence of Tertiary, Mesozoic and Permian rocks, the age of the sediments below 2756 metres being at present uncertain. This report presents lithological data and stratigraphic...

Four stratigraphic wells were drilled, totalling 5023 feet were drilled, Karkaro No. 1, Mount Furner No. 1, Wallira No 1 and Wallira No. 2 to verify Permian sediments and identify basement reflector. Results indicate shallow platform covered by thin...

Basal sediments of the western Great Artesian Basin record the change from a continental to marine depositional environment during the early Cretaceous. The sequence consists of the Algebuckina Sandstone, the Cadna-Owie Formation and the Mount Anna...

Cootanoorina 1 was drilled about 33 miles south-southwest of Oodnadatta township by the South Australian Department of Mines, as a combined 'on structure' and stratigraphic test in the Arckaringa Sub-Basin region of the Great Artesian Basin. The main...

Mount Willoughby 1 was drilled in the northern part of the Arckaringa Basin as a continuation of the SA Department of Mines stratigraphic study of this area. The well was drilled on the western plateau of a positive gravity high on the Wintinna 1 mile...

Biostratigraphy of drill core and cuttings was erected for Mt Willoughby, and some biostratigraphy of the Lambina 1 was revised. Problems with contamination were encountered.

Preliminary map was prepared from mapping and shot hole logging. Precambrian crystalline basement is overlain by Permian, Mesozoic and Tertiary sediments. Younger exposed units include gypsiferous clays, sandstone and calcrete.

The Gason 1:250 000 sheet area is centred about 850 km north of Adelaide, in the South Australian portion of the Great Artesian Basin. The area mapped includes most of the Gason Dome, a gentle upwarp in a relatively flat-lying sequence of Mesozoic and...

Six bore holes have been drilled between previously existing productive holes to lessen water carting distances during railway construction. Drilling targets were the Cadna-Owie Formation and/or the Algebuckina Sandstone. All holes were productive at...

The NOOLYEANA 1:250 000 sheet area lies in the northern portion of the Great Artesian Basin in South Australia. The area mapped includes the southern part of the Simpson Desert and the very northern end of Lake Eyre North. The oldest outcrops in the...

Pronounced positive and negative geophysical anomalies on EVERARD represent the crystalline Musgrave Block in the north, a basement trough more than 4 km in depth that flanks the Musgrave Block to the south, and the crystalline Ammaroodinna Inlier to...
