Dipole Configuration

Preliminary investigations at well sites in the Coonamble Basin, New South Wales, have demonstrated that deep resistivity soundings can provide valuable information in petroleum exploration with relative ease. The correct thickness of the unmetamorphosed basin sediments was accurately defined from resistivity data whereas interpretation of seismic reflection and aeromagnetic data had previously yielded large over‐estimates. Field procedures can be conducted in a manner suitable to routine prospecting. The dipole configuration has certain advantages in this respect, not the least of which is its ability to resolve low dips in sedimentary basins. Synthetic sounding curves calculated on a digital computer from digitized well log resistivity data are useful to predict the results to be expected from an actual field sounding and greatly facilitate the interpretation of the results.

New Approach

Aeromagnetic surveys have been generally regarded in petroleum exploration as a reconnaissance tool for major structures. They were used commonly in the early stages of exploration to delineate the shape and depth of the sedimentary basin by detecting the strong magnetic contrast between the sediments and the underlying metamorphic basement. Recent developments in the application of computer technology to the study of the earth's magnetic field have significantly extended the scope of aeromagnetic surveys as a tool in the exploration for hydrocarbons. In this paper the two principal methods used in the analysis and interpretation of aeromagnetic data over sedimentary basins are: 1) energy spectral analysis applied to gridded data; and, 2) automatic curve matching applied to profile data. It is important to establish the magnetic character of sedimentary and basement rocks, and to determine the regional magnetic character of the area by applying energy spectral analysis. Application of automatic curve matching to profile data can provide results from the sedimentary section and deeper parts of a basin. High quality magnetic data from an experimental aeromagnetic survey flown over part of the Eromanga/Cooper Basin has recently been interpreted using this new approach. From this survey it is possible to detect major structures such as highs and troughs in the weakly magnetic basement, as well as pick out faults, and magnetic layers in the sedimentary section. The results are consistent with interpretation from seismic and demonstrate that aeromagnetic data can be used to assist seismic interpretation, for example to interpolate between widely spaced seismic lines and sometimes to locate structures which can not be detected from seismic surveys. This new approach to the interpretation of aeromagnetic data can provide a complementary tool for hydrocarbon exploration, which is ideal for logistically difficult terrain and environmentally sensitive areas.

Coal Measures

The Clarence-Moreton Basin covers an area of some 28 000 km2 in north-eastern New South Wales and south-eastern Queensland. The basin is relatively unexplored, with a well density in New South Wales of one per 1600 km2. Since 1980, Endeavour Resources and its co-venturers have pursued an active exploration programme which has resulted in the recognition of significant petroleum potential in the New South Wales portion of the basin.Previous studies indicated that the Upper Triassic to Lower Cretaceous Clarence-Moreton Basin sequence in general, lacked suitable reservoirs and had poor source- rock potential. While exinite rich, oil-prone source rocks were recognised in the Middle Jurassic Walloon Coal Measures, they were considered immature for oil generation. Moreover, during the 1960's the basin acquired a reputation as an area where seismic records were of poor quality.These ideas are now challenged following the results of a new round of exploration which commenced in the New South Wales portion of the basin in 1980. This exploration has involved the acquisition of over 1000 km of multifold seismic data, the reprocessing of some 200 km of existing single fold data, and the drilling of one wildcat well. Over twenty large structural leads have been identified, involving trapping mechanisms ranging from simple drape to antithetic and synthetic fault blocks associated with normal and reverse fault dependent and independent closures.The primary exploration targets in the Clarence- Moreton Basin sequence are Lower Jurassic sediments comprising a thick, porous and permeable sandstone unit in the Bundamba Group, and channel and point-bar sands in the Marburg Formation. Source rocks in these and the underlying Triassic coal measures are gas-prone and lie at maturity levels compatible with gas generation. In contrast, it was established from the results of Shannon 1 that the Walloon Coal Measures are mature for oil generation and this maturity regime is now considered to be applicable to most of the basin in New South Wales.A consideration of reservoir and source rock distribution, together with structural trends across the basin in Petroleum Exploration Licences 258 and 259, has led to the identification of three prospective fairways, two of which involve shallow oil plays. Exploration of these fairways is currently the focus of an ongoing programme of further seismic data acquisition and drilling.

Stratigraphic Sequences

The onshore energy security program, funded by the Australian Government and conducted by Geoscience Australia, has acquired deep seismic reflection data across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Detailed interpretation of deep seismic reflection profiles from four onshore basins, focussing on overall basin geometry and internal sequence stratigraphy, will be presented here, with the aim of assessing the petroleum potential of the basins. At the southern end of the exposed part of the Mt Isa Province, northwest Queensland, a deep seismic line (06GA–M6) crosses the Burke River structural zone of the Georgina Basin. The basin here is >50 km wide, with a half graben geometry, and bounded in the west by a rift border fault. Given the overall architecture, this basin will be of interest for petroleum exploration. The Millungera Basin in northwest Queensland is completely covered by the thin Eromanga Basin and was unknown prior to being detected on two seismic lines (06GA–M4 and 06GA–M5) acquired in 2006. Following this, seismic line 07GA–IG1 imaged a 65 km wide section of the basin. The geometry of internal stratigraphic sequences and a post-depositional thrust margin indicate that the original succession was much thicker than preserved today and may have potential for a petroleum system. The Yathong Trough, in the southeast part of the Darling Basin in NSW, has been imaged in seismic line 08GA–RS2 and interpreted in detail using sequence stratigraphic principles, with several sequences being mapped. Previous studies indicate that the upper part of this basin consists of Devonian sedimentary rocks, with potential source rocks at depth. In eastern South Australia, seismic line 08GA–A1 crossed the Cambrian Arrowie Basin, which is underlain by a Neoproterozoic succession of the Adelaide Rift System. Stratigraphic sequences have been mapped and can be tied to recent drilling for mineral and geothermal exploration. Shallow drill holes from past petroleum exploration have aided the assessment of the petroleum potential of the Cambrian Hawker Group, which contains bitumen in the core, indicating the presence of source rocks in the basin system.

The Way

The petroleum industry in Australia is at the centre of a web of complex laws. In addition to the legislation under which petroleum exploration and production tenements are granted there is a multiplicity of statutes and regulations, Commonwealth and State, which have a direct bearing on the conduct of those involved in exploring for or exploiting Australia's petroleum reserves. For example, the level of participation by foreigners is governed by the Commonwealth Foreign Investment Guidelines and the Foreign Takeovers Act 1975; the Commonwealth has control over the export of petroleum under the Customs (Prohibited Exports) Regulations and domestic markets are subject to the operation of the Crude Oil Allocation Scheme. The Commonwealth continues to have the right to regulate the transfer of funds to and from Australia under the Banking (Foreign Exchange) Regulations. Certain States such as South Australia and New South Wales have their own foreign investment guidelines.Not only this, there are revenue laws which govern very much the way in which petroleum projects are organised, interests transferred and otherwise dealt with and finance made available, such as State stamp duty legislation, Commonwealth income tax laws, and Commonwealth legislation imposing registration fees on dealings in exploration permits and production licences. A new tax, Resource Rent Tax, is to be introduced.Then there are laws which have an indirect bearing on petroleum activities such as the Companies Code which, in addition to governing the administration and organisation of companies, controls the way funds can be raised.The statutory and regulatory framework is only part of the picture. The rights and obligations of participants in petroleum projects as between themselves are almost always set out in a joint venture or joint operating agreement, the combination between the participants being known as an unincorporated joint venture. This form of business organisation is not a partnership; it is not the creature of legislation. Indeed it has been rarely referred to in Acts of Parliament. Problems arising under the joint venture agreement will be considered against the backdrop of the general law which unfortunately has seldom been called upon to resolve disputes between participants in joint ventures. An illustration of one of these rare instances is Brian Pty Ltd v United Dominions Corporation Ltd (1983), where the New South Wales Court of Appeal considered the fiduciary relationship of joint venturers.Despite this legislative and regulatory' backdrop and the uncertainties as to the true effect of joint venture agreements, the industry up until quite recently has survived with little litigation. This is no longer the case. Recent and pending litigation shows that there is no reluctance on the part of participants to take their disputes to court, often at great expense and with unfortunate results for previously close relationships. It must now be said that money spent to achieve proper and clear agreement on organisational and legal matters at the earliest stage of a project is money just as well spent as that on drilling and other operational activities.

Progressive Reforms

Soil is a valuable natural resource. In the state of New South Wales, Australia, the governance of soil has evolved since Federation in 1901. Following rapid agricultural development, and in the face of widespread soil degradation, the establishment of the Soil Conservation Service marked a turning point in the management of soil. Throughout the 20th century, advances in knowledge were translated into evolving governance frameworks that were largely reactionary but saw progressive reforms such as water pollution legislation and case studies of catchment-scale land and vegetation management. In the 21st century, significant reforms have embedded sustainable use of agricultural soils within catchment- and landscape-scale legislative and institutional frameworks. What is clear, however, is that a multitude of governance strategies and models are utilised in NSW. No single governance model is applicable to all situations because it is necessary to combine elements of several different mechanisms or instruments to achieve the most desired outcomes. Where an industry, such as the sugar industry, has taken ownership of an issue such as acid sulfate soil management, self-regulation has proven to be extremely effective. In the case of co-managing agricultural soils with other landuses, such as mining, petroleum exploration and urban development, regulation, compliance and enforcement mechanisms have been preferred. Institutional arrangements in the form of independent commissioners have also played a role. At the landscape or total catchment level, it is clear that a mix of mechanisms is required. Fundamental, however, to the successful evolution of soil governance is strategic investment in soil research and development that informs the ongoing productive use of agricultural landscapes while preventing land degradation or adverse environmental effects.
