Exploration over Roper Group outcrop in the McArthur Basin prompted Pacific Oil & Gas to investigate the petroleum potential of the Beetaloo Sub-basin, a 15 000 km2 Proterozoic depression concealed beneath Phanerozoic cover. Since 1989 drilling and seismic has identified a broadly flat-lying sequence with uplifted, eroded margins. A 3 500 m composite Proterozoic section consisting of three sandstone-to-mudstone sequences has been drilled. The lower two sequences comprise conformable units of the Mesoproterozoic upper Roper Group and unconformably overlying them is a previously unknown sequence comprising the informally labelled 'Jamison Sandstone' and 'Hayfield Mudstone', probably of Neoproterozoic age.Organic-rich intervals in the Roper Group mudstones range one to three per cent TOC in the Kyalla Member, and two to seven per cent TOC in the 'Middle' Velkerri Formation. Across most of the sub-basin the oil window lies within the Kyalla Member around 900–1350 m, while the 'Middle' Velkerri Formation is around 2 500 m and well into overmaturity, but may still have potential for gas. Potential reservoirs in the Bessie Creek, Moroak and 'Jamison' Sandstones, and in sandy units within the mudstones, are compromised by diagenesis, but porosities of up to 20 per cent and permeabilities of tens and rarely hundreds of millidarcies have been measured. Encouraging shows were observed in many of these intervals, and small quantities of oil and gas have been recovered in drill stem tests. With only a few targets drilled to date, this frontier area requires more exploration before its hydrocarbon potential can be adequately assessed.

Exploration Activity

The petroleum industry in Australia is going through a major development phase with export LNG projects under construction on both the east and west coasts. Initial exploration for shale and tight gas has opened up new plays as well as increasing interest in many sedimentary basins that have been overlooked. Access to land onshore in Australia for petroleum exploration is, in some States, through a formal release process by the relevant jurisdiction. This is a compilation of material supplied by the States and Northern Territory in relation to land being made available onshore for petroleum exploration. Not all jurisdictions have new acreage available for exploration. In these cases, new initiatives being undertaken that directly relate to accessing land for exploration or the present state of exploration activity will be highlighted. Land that is being made available for exploration will generally be accompanied by information regarding its geological setting and petroleum potential. Previous exploration activity may be in summaries, including information in relation to the amount of pre-existing data available to future explorers. Exploration opportunities may include conventional and unconventional targets. The review of the areas may also include maps and sections related to the land being made available.

The structure and seismogeological characteristics of the Achimov strata of the Gydan Peninsula are considered. Geological and geophysical criteria for the regional forecast of oil and gas potential, taking into account the clinoform structure of the Berriasian-Lower Aptian deposits, are proposed. Based on the interpretation of drilling data and 2D seismic exploration, predictive maps of the thickness of sand bodies were constructed, depocenters of accumulation of sandy material were mapped. Seismostratigraphic studies, which are based on a comprehensive analysis of the wave pattern of time seismic sections, dynamic and seismic facies analyzes, as well as paleotectonic and paleogeomorphological reconstructions, made it possible to identify the Salmanovskaya and Yuzhno-Gydanskaya oil and gas zones in the Achimov strata of the Gydan Peninsula.

Peter Green is the Geoscience Manager: Energy Geoscience in the Geological Survey Queensland and has extensive experience in basin studies, geoscience and the development of petroleum regulation in Queensland. This paper provides a summary of the land releases for petroleum exploration for onshore areas and coastal waters of Australia for 2010. The summaries include upstream petroleum acreage opportunities for the states and the Northern Territory, and geothermal energy exploration opportunities. The rise in interest in export liquefied natural gas projects has ensured petroleum exploration and production has remained strong. Interest in acquiring petroleum acreage to explore for both conventional and non-conventional plays remains high. Australian state and the Northern Territory governments continue to provide access to land and promotional opportunities for companies to undertake exploration and development of our petroleum resources. Acreage on offer provides a mix of exploration opportunities from conventional oil and gas through to the unconventional plays such as shale gas and tight gas. This change in acreage on offer reflects the changing nature of the onshore petroleum industry in Australia.

In the article, when considering the prospects of oil and gas potential of the Riphean strata in Siberia as indicators of oil content, special attention is paid to hydrocarbon gases in sorbed form. Sorbed hydrocarbon gases are still poorly used as indicators of oil content, although they have significant prerequisites for this. Some of them can be understood by reading this article.

Complex interpretation of seismic and parametric drilling data is performed. The data for interpretation are obtained within the conjunction zone of the Kureyka syncline and the Anabar anteclise. As a result of complex interpretation the structural maps on the bottom of Vendian and the top of the Kuonamka formation are constructed. Map of the Vendian terrigenous complex was constructed. High prospects of oil and gas potential of the lower-middle Cambrian sediments are shown. Based on the analysis of logging data, core description and detailed correlation of time sections, the litho-acoustic models were compiled for two profiles crossing the barrier-reef system, and two-dimensional synthetic time sections were calculated. Obtained results confirm the correctness of the ideas about the internal structure of the Vendian-Cambrian complexes.

The article is devoted to the assessment of the oil and gas potential of the deep Ordovician-Lower Devonian oil and gas complex in the south-east of the Timan-Pechora oil and gas province. Within the Upper Pechora Basin of the Pre-Ural trough and in the south of the Pechora-Kolva aulacogen, several wells were drilled with a depth of more than 5 km, some of which entered the Lower Paleozoic deposits. These strata are difficult to access and poorly studied, and the prospects for their oil and gas potential are unclear. The article describes the composition of the complex, gives geochemical characteristics, describes reservoir properties, and presents the results of 1D and 2D basin modeling. Models of the zoning of catagenesis are presented. The oil and gas complex includes a variety of oil and gas source rocks. It is possible to allocate collectors, as well as the seals. In the Lower Paleozoic sediments, the processes of oil, gas and gas condensate generation took place, which could ensure the formation of deposits both in the deep strata of the Lower and Middle Paleozoic, and in the overlying horizons. The generation and accumulation of hydrocarbons in deep-buried sediments occurred at a favorable time for the formation of deposits. However, it is considered that the scale of hydrocarbon generation for the Lower Paleozoic deposits is not high.

This article is devoted to the problem of studying the petroleum potential of the underexplored territories of the European part of Russia, in particular, the Vychegda trough. Taken a new approach to assessing the hydrocarbon potential of the Vychegda trough, based on the allocation of petroleum systems, widely used abroad. Based on a comprehensive analysis of the geological structure of the deflection and geological-geochemical results, including those obtained by the authors, two potential petroleum systems – “domanic” and “riphean” – were identified. The potential domanic petroleum system dominates in the Eastern regions and is a peripheral fragment of the regional petroleum system covering the territory of the Volga-Ural and Timan-Pechora basins. The system is linked to development in the South-Eastern part of the trough and the neighbouring Solikamsk depression of bituminous domanic and domanicoid sediments as a source rock, which is confirmed by the genetic correlation of crude oils of Devonian-Carboniferous deposits of the Northern districts of Solikamsk depression with domanic biomarker. The stratigraphic range of the domanic system is upper Devonian-upper Permian; the formation time is late Devonian-Mesozoic. The potential Riphean hydrocarbon system can be identified by the fact of oil-bitumen occurrences in the Proterozoic strata and the presence of the productive source rocks in the upper Riphean. The source rocks were at oil window. The Riphean system can cover the entire territory of the Vychegda trough, and the section from the Riphean to upper Permian sediments. The time of the system formation – Riphean-Mesozoic. Due to large thickness of the Riphean sediments, even with a large loss of hydrocarbon potential, the residual potential hydrocarbon resources of the Riphean petroleum system can be very significant. Based on the research conducted, prioritized exploration studies are substantiated.
