The evolutionary-genetic method, whereby modern sedimentary basins are interpreted as end-products of a long geological evolution of a system of conjugate palaeo-basins, enables the assessment of the petroleum potential of the Western sector of the Russian Arctic. Modern basins in this region contain relics of palaeo-basins of a certain tectonotype formed in varying geodynamic regimes. Petroleum potential estimates of the Western Arctic vary broadly—from 34.7 to more than 100 billion tons of oil equivalent with the share of liquid hydrocarbons from 5.3 to 13.4 billion tons of oil equivalent. At each stage of the development of palaeo-basins, favourable geological, geochemical and thermobaric conditions have emerged and determined the processes of oil and gas formation, migration, accumulation, and subsequent redistribution between different complexes. The most recent stage of basin formation is of crucial importance for the modern distribution of hydrocarbon accumulations. The primary evolutionary-genetic sequence associated with the oil and gas formation regime of a certain type is crucial for the assessment of petroleum potential. Tectonic schemes of individual crustal layers of the Western sector of the Russian Arctic have been compiled based on the interpretation of several seismic data sets. These schemes are accompanied by cross-sections of the Earth’s crust alongside reference geophysical profiles (geo-traverses). A tectonic scheme of the consolidated basement shows the location and nature of tectonic boundaries of cratons and platform plates with Grenvillian basement as well as Baikalian, Caledonian, Hercynian, and Early Cimmerian fold areas. Four groups of sedimentary basins are distinguished on the tectonic scheme of the platform cover according to the age of its formation: (1) Riphean-Mesozoic on the Early Precambrian basement; (2) Paleozoic-Cenozoic on the Baikalian and Grenvillian basements; (3) Late Paleozoic-Cenozoic on the Caledonian basement; (4) Mesozoic-Cenozoic, overlying a consolidated basement of different ages. Fragments of reference sections along geo-traverses illustrate features of the deep structure of the main geo-structures of the Arctic shelf and continental regions of polar Russia.

A number of sedimentary basins of various ages are located onand offshore Vietnam (Fig. 1). Some of them have significant petroleum resources and have thus attracted interest from industry and academia (Rangin et al. 1995; Matthews et al. 1997; Lee & Watkins 1998; Lee et al. 2001). Moreover, Vietnam is located in a position central to the understanding of the geological development of South-East Asia (Hall & Morley 2004). The structural style and the stratigraphy of the Vietnamese basins thus provide a valuable record about the development of South-East Asia throughout the Phanerozoic and the subsequent Eocene as well as younger deformation associated with the collision and indentation of India into Eurasia and the opening of the South China Sea (Fyhn et al. 2009a, 2010a).

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 rapidly increasing interest that has been shown in the petroleum potential of the Arctic during the last decade has caused attention to be focussed on the sedimentary basins of Greenland and its offshore areas. During the period up to 1966 sporadic interest was shown in the petroleum potential of onshore West Greenland. In 1966 parties from two oil companies visited Nûgssuaq and Disko. None of this work was followed up by geophysical surveys or drilling.

The Vietnam Petroleum Institute (VPI) and the Geological Survey of Denmark and Greenland (GEUS) have carried out a programme of geoscientific research and institutional capacity building since 1995. It has included geoscientific projects focused on assessment of the hydrocarbon potential of selected sedimentary basins, technology transfer and inhouse training at VPI in Hanoi and at GEUS in Copenhagen. Co-operation is continuing within the framework of a new, long-term project that aims to strengthen research capacity in Vietnam within the fields of basin analysis and modelling.
