Two oil samples from the Birkhead Formation oil reservoir in Spencer 3 and Spencer 4, and five sidewall cores taken from the Bulldog Shale, Murta Member, Hutton Sandstone, Poolowanna Formation and Patchawarra Formation in Spencer 3 were subjected to...

Five wells along a north-south trending section in the southern Eromanga Basin were studied using petrographic techniques to delineate petroleum source rocks and possibly aid in environmental interpretation. The dispersed organic matter (d.o.m.) in...

Organic geochemical analyses of 20 crude oil samples from twelve wells were performed to determine if any genetic oil families could be identified within the Eromanga-Cooper Basin area. The results have been plotted graphically to demonstrate the...

This report is intended to be a convenient single reference to the Cattlegrid ore deposit geology. It represents an updated summary of a large amount of data, gleaned largely from internal company reports. The subject matter relates mainly to the...

Organic geochemical analyses were performed on 14 conventional core samples taken from the Epsilon, Murteree and Patchawarra formation intervals in Wancoocha 1 and on 3 similar samples from the Birkhead Formation in Wancoocha 4. The rock sample...

Contains drill cuttings and core descriptions, some brief results for conventional core analyses plus basic source rock quality evaluation of the Cretaceous section, and a detailed organic petrology study report. The latter study investigated 12...

In June 1996 MESA commissioned the Centre for Petroleum and Environmental Organic Geochemistry at Curtin University with $30 000 to investigate the applications to the Cooper-Eromanga Basin system of new molecular geochemical concepts recently...

During licence Year 6, on renewed EL 2697, AngloGold drilled a total of 177 vertical RAB holes (LER2508 – LER2679) for 9975 m plus 20 inclined RC holes (LRC360 – LRC379) for 2964 m. The drilling of 97 RAB holes at the Smith prospect revealed a 300 m x...

TARGET: In an untested area immediately west of Leigh Creek, extending as far as the eastern side of Lake Torrens, ETSA was aiming to find buried deposits of Late Palaeozoic or Mesozoic coal of a rank at least equal to that of Leigh Creek coal (and...

A large part of the Harris Greenstone Domain basement tectonostratigraphic block, extending from 10 km to 130 km west of Kingoonya, is being explored for possible buried economic gold, nickel and other base metal mineralisation which may be associated...

In the sixth year of the project, the principal activity was the drilling of two inclined diamond holes for 633.5 m during October 2008 to investigate a possible northern buried extension of the known Rankine Trend mineralisation on EL 3641 ground...

As part of continuing brownfields exploration for extensions to known stratiform base metal mineralisation in the area lying to the west of Pernatty Lagoon, much stratigraphic drilling (210 rotary percussion holes totalling 12,441 m, including 1167 m...

The dispersed organic matter content of drill cuttings samples from the subject wells was examined microscopically to assess its hydrocarbon potential. In general it appears that the Cretaceous and Permian sediments are unlikely to be good source...

Gasoline range hydrocarbon analysis, carbon isotope analysis of C12+ saturates and aromatics and GC-MS analysis of C12+ naphthenes provide a consistent picture of the source affinity and thermal maturity of Cretaceous (Murta Member-type) and Jurassic...

An extensive orientation biogeochemical survey established that the copper content in the branch twigs of two wattle tree species, Acacia aneura and Acacia linophylla, is an indicator of near-surface copper mineralisation. A number of anomalies...

6 drill core samples and 68 drill cuttings samples from selected organic-rich intervals in 4 Eringa Trough wells were subjected to organic geochemical and petrographic analyses to enable assessment of their hydrocarbon generative potential. Following...

Many ditch cutting samples from Gidgealpa No.3, Innamincka No.l and Tinga Tingana No.l wells, covering a wide geological succession (Permian to Cretaceous) were supplied to CSIRO by Delhi International Oil Corporation. The samples were originally...

Port Julia 1A was recently drilled by BHP Minerals in EL 1112 to investigate a bullseye magnetic anomaly, but failed to realise its mineral-related objective. The well was fully cored through the Cambrian Coobowie Limestone, Moonan Formation and...

This is the final in a series of reports prepared for MESA, in which the hydrocarbon source potential of the Pedirka, Simpson and western Eromanga Basins is re-evaluated. Previous work focused on the Eringa Trough of the Pedirka Basin and the...

Contains the results of organic geochemical analyses performed on two oil-stained siltstone and sandstone drill cuttings samples obtained from 101.4 and 107.9 metres depth in bore NB/SR 12, and on two core samples cut from 161.3 and 196.8 metres depth...
