Since commencing operatorship in the Amadeus Basin in June 1980, the Amadeus Joint Venture has acquired 3000 km of multifold seismic data and reprocessed 2500 km of existing single fold and multifold data. These data, integrated with geological, Landsat, gravity and airphoto information, led to the drilling of eight exploration wells, which resulted in two gas discoveries (in the Dingo 1 and West Walker 1 wells) and numerous additional oil and gas shows in the remaining wells.Interpretation of these multi-discipline data has enabled a number of significant structural trends and styles in the Amadeus Basin to be defined. Individual prospects within some of the major structural trends have now been tested by the drill. This paper describes the nature of these structural trends and illustrates geologically and geophysically typical examples of drilled prospects existing within these trends.The primary exploration targets in the Amadeus Basin are the Ordovician Stairway and Pacoota Sandstones (confirmed by the Mereenie Oil and Gas Field, Palm Valley Gas Field, and the West Walker gas discoveries) and the Precambrian-basal Cambrian Arumbera Sandstone (confirmed by the Dingo gas discovery). Geochemical and maturation data indicate that significant additional oil and gas accumulations can be discovered in these formations.Data from Dingo 1, Mt Winter 1 and Finke 1 have again indicated that significant quantities of both oil and gas have been generated in the Late Proterozoic sediments of the Basin. An active exploration program is continuing and will endeavour to confirm these expectations.

The work is devoted to the development of geochemical criteria for determining the nature of saturation for deep-adsorbed gases in the core. As the object of investigation used the core material selected in the fields in the Nadym-Pyrskoy oil and gas field. In each sample, 72 components were determined, namely, hydrocarbons of different material groups: normal, branched, polycyclic, and aromatic compounds from butane to dodecane. With respect to the quantitative distribution and correlation among the components, qualitative geochemical indicators of sediment productivity have been developed. The saturation character established by the criteria of deep-adsorbed gases was confirmed by the test results. In this regard, this research method significantly increases the effectiveness of diagnostics of prospective deposits, the application of which is relevant in the territory of the West Siberian oil and gas basin, especially when studying deep-submerged deposits of complex geological structure.

During August 1984, a conventional 2D seismic line and a single fold 3D seismic survey were recorded over the Woodada Gas Field, North Perth Basin, Western Australia. This survey was a joint venture between the Allied Geophysical Laboratories at the University of Houston and the Exploration Seismology Centre's Field Research Laboratory at the Western Australian Institute of Technology. Previous seismic data were so poor that there was confusion about fault orientation and structure in the survey area. In addition, the fault strike direction and extent were unknown at this location. Consequently, 3D seismic acquisition and processing techniques appeared highly applicable to this geological problem.In general, progressive development of seismic data acquisition methods has been towards higher channel, higher multifold 2D and 3D surveys. However, at the Allied Geophysical Laboratories, processing techniques for single-fold 3D data have been developed using model tank data. This processing technique — LO-FOLD 3D — was used to field trial the method, and to test its ability to define faulting between the gas producing well Indoon 1 and dry step-out well Woodada 9. Previous usage of the single-fold 3D survey method was to delineate reefal structures in the Michigan Basin. Beyond this, no published articles discuss the method.With single-fold data, velocity analysis and coherent noise are a problem. Consequently, 2D bin lines through the 3D volume of data were processed in order to improve the signal to noise ratios. The objective was to delineate the fault orientation in the Carynginia Formation, located between 1.3 and 1.5 seconds. Fault delineation was determined from 2D bin lines and time slices, and is interpreted to run diagonally between the two wells.

Internationally the research of low permeability oil reservoir is a difficult point in the exploration and development of oil and gas field. This thesis, based on the research methods of low permeability reservoirs at home and abroad, summaries several major problems encountered in the process of low permeability oil exploration and development under the current technical conditions as well as the corresponding, but more effective technical measures that need to be constantly improved. And that exploration and development of low permeability of the reservoir will be the main battle field for some time in the future of oil exploration and development.
