Unconventional hydrocarbons - Australia's old rocks prove their worth

Australia’s search for petroleum began in the onshore basins where extensive areas of Paleozoic marine sequences, with some high-quality source rock intervals and spectacular outcrop, encouraged sporadic exploration for many decades. For these efforts, there were some rewards, including the discovery of the Mereenie oil field in Ordovician rocks, the Amadeus Basin in 1960s, and the Blina discovery in Devonian carbonates in the Canning Basin during the early 1980s. Since the late 1980s, however, the focus of exploration has shifted offshore where more and larger discoveries were made in the Mesozoic marginal basins, which today contain about 90% or more of Australia’s conventional oil and gas. Now, however, the focus has shifted back to the onshore, recognising the potential for shale and tight gas and oil in these older rocks. The onshore basin area under exploration license has nearly doubled from 2010 to 2012; several major international companies have joined local explorers in testing the worth of Australia’s lower Paleozoic and Proterozoic petroleum systems, and new discoveries have been made in several basins. Geoscience Australia and its partners in the state and NT surveys are undertaking new assessments and studies across a number of these basins.

Rodinga, NT, 1990 (P1016), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Rodinga, NT, 1990 survey were acquired in 1990 by the NT Government, and consisted of 51146 line-kilometres of data at 300m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Innamincka No. 1 Well, South Australia Of Delhi Frome Santos

The Innamincka No. 1 test well, drilled by Delhi Australian Petroleum Ltd, Frome Broken Hill Company Pty Ltd, and Santos Limited, in the north-east corner of South Australia, penetrated the strata below the surface in the deeper portion of the Great Australian Artesian Basin to a total depth of 12,637 feet. The test was begun late in March, 1959, using a National 130 drilling rig operated by Delta Drilling Company. The operation, under supervision of drilling, engineering, and geological personnel of Delhi Australian Petroleum Ltd, involved an extensiveprogranune to obtain technical data relative to the
occurrence of hydrocarbons in the strata cut by the drill bit, as well as stratigraphical information concerning the geological history of the area. Included in the operation was a full complement of logging, coring, and testing programmes provided and conducted by the operating Company and their Contractors.
Innamincka No. 1 established the presence of at least 6,723 feet of Mesozoic sediments, as well as 5,914 feet of sediments of Palaeozoic age at the wellsite. Several minor showings of hydrocarbons were encountered within the Mesozoic sequence below 3,928 feet in nonmarine sediments; however, after thorough examination and testing, the shows proved inconsequential. Several zones within the interval 4,390 feet to 7,050 feet evidenced physical qualities such that the rock could be classified as mechanically favourable as reservoir type rock, but an analysis of the sediments suggested that their origin was not favourable as hydrocarbon source rocks. The intervals 0 feet to 4,390 feet and 7,050 feet
to 12,637 feet did not suggest qualities of either source-bed or reservoir type rocks.
The well was completed in late November, 1959 as an artesian water well from the Blythesdale Formation through perforations between 4,390 feet to 4,560 feet.

A commentary on the metallogenic map of Australia and Papua New Guinea

A metallogenic map depicts concentrations of deposits of metals within their geological framework, and attempts to relate one to the other. The more familiar mineral deposits map, on the other hand, is designed to show the geographical distribution of mineral deposits, possibly with indications of their size, state of exploitation, and other factors.The exact nature of the legend for a metallogenic map is governed by the relationships assumed to exist between the concentrations of metals and their settings: map design can be used to emphasize the more important facts and employs symbols each of which incorporates several parameters. Metallogenic maps are not simple and easily read documents, but are complex representations of complex relationships, and so should convey a great deal of information. In 1956, at the 20th Session of the International Geological Congress in Mexico, the Commission for the Geological Map of the World set up a Sub-Commission for the Metallogenic Map of the World. After studying available maps showing mineral deposits, the sub-commission recommended that although countries should continue experimentation towards suitable presentation of data, an Editorial Committee for the Metallogenic Map of Europe should be set up; this committee would work towards firstly a legend for metallogenic maps in general, and secondly a Metallogenic Map of Europe. The committee was fortunate in that the compilation of the Tectonic Map of Europe was well advanced when it began its work. In 1964 a legend reflecting the basic philosophy of the Metallogenic Map of Europe was prepared and compilation begun. The first two sheets of the Metallogenic Map at a scale of 1:2 500 000 were published in 1969. Australia was represented on the sub-commission from 1960 onwards. The presentation of the legend for the map of Europe paved the way for the Australian compilation. A suitable area was selected for a pilot compilation early in 1965 and the main study began in 1966. A suitable geographical base map of Australia at 1:5 000 000 was available and a geological map on this base was in the final stages of publication. The second edition of the Mineral Deposits Sheet of the Atlas of Australian Resources (scale 1:6 000 000) was published during 1965. In that year the Tectonic Map Committee of the Geological Society of Australia began work on a Tectonic Map of Australia, and the philosophies and preparation of that and the Metallogenic Map were developed together.

Depth to magnetic basement map of the Gawler-Curnamona region, South Australia 1:750 000 scale

The depth to magnetic basement map was constructed from a compilation of point located depth values in metres below topography consisting of depth to magnetic source estimates, basement drill hole intersections, interpreted seismic depth estimates. These point depths were combined with mapped geology to delineating the outcropping basement, and then gridded.  
The depth to magnetic basement in this study is interpreted to delineate the top of the pre-Neoproterozoic. There are three exceptions which are due to the nature of the magnetisation of these units. The first two exceptions (Pandurra Formation and sediments of the Adelaide Geosyncline) has resulted in a portion of the horizontal extent being assigned to the magnetic basement and the remainder, to the low to non-magnetic cover, while the third (sediments of the Adelaide Geosyncline) has resulted in the lower sequences being assigned to the basement and the upper sequences to the cover.

Curnamona, SA, 2003 and 2004 seismic survey (L164) operations report

A seismic survey using  Australian National Seismic Imaging Resource (ANSIR) Hemi60 Vibroseis vehicles, ARAM24 acquisition equipment and Pelton controllers was carried in the Curnamona province of South Australia over two periods, August 2003 and July 2004. A total of 197.6 km of 2-D data was collected to 18 seconds two way time over a single line at 60 fold CDP coverage.
The project was undertaken to meet the objectives of ANSIR proposal 03-02R as lodged by researchers from Primary Industries and Resource, South Australia (PIRSA), Office of Minerals, Energy and Petroleum, SA. The principal scientific objective of this survey was to provide a regional crustal seismic image of the Curnamona Province. This dataset will assist in the understanding of the geological architecture and resource potential of the region particularly in areas under cover. This line links with a seismic transect in the Broken Hill Block undertaken by Australian Geological Survey Organisation (AGSO) in 1996 and provides a future opportunity for an eventual east-west continuation across the Adelaide Geosyncline and the Gawler Craton.
The survey was funded by PIRSA, Office of Minerals, Energy and Petroleum, SA and the Predictive Minerals Discovery Cooperative Research Centre (pmd*CRC) with project supervision undertaken by ANSIR and in-kind support from Geoscience Australia (GA).
