Cutting-edge techniques have always been utilized in petroleum exploration and production to reduce costs and improve efficiencies. The demand for petroleum in the form of oil and gas is expected to increase for electricity production, transport and chemical production, largely driven by an increase in energy consumption in the developing world. Innovations in analytical methods will continue to play a key role in the industry moving forwards as society shifts towards lower carbon energy systems and more advantaged oil and gas resources are targeted. This volume brings together new analytical approaches and describes how they can be applied to the study of petroleum systems. The papers within this volume cover a wide range of topics and case studies, in the fields of fluid and isotope geochemistry, organic geochemistry, imaging and sediment provenance. The work illustrates how the current, state-of-the-art technology can be effectively utilised to address ongoing challenges in petroleum geoscience.

Geochemical Investigation

Vitrinite reflectance suppression in marine sequences is a major problem facing some petroleum exploration companies. It leads to considerable difficulties in determining thermal maturity in exploration provinces like the North West Shelf of Australia. The Permian Greta seam, northern Sydney Basin, is a classical example of a marine-influenced coal which displays a vitrinite reflectance suppression of 0.25 per cent R0. It is an ideal candidate for detailed organic geochemical investigation of this problem. The amount and composition of extractable hydrocarbons in the coal appear to be only partially related to vitrinite reflectance, so it is unlikely that suppression is directly caused by the adsorption of hydrocarbons into the vitrinite matrix. Vitrinite reflectance is inversely proportional to the H/C atomic ratio, suggesting that the observed suppression is caused by the more perhydrous nature of vitrinite in marine-influenced coals. At the molecular level the marine influence can clearly be distinguished in the top metre of the seam by depleted amounts of n-alkanes with a lower carbon preference index and a slightly bimodal distribution, a lower pristane/phytane ratio and considerably more hopanes and diasteranes. In addition to the peat-derived humic compounds prevalent throughout the seam, these geochemical parameters indicate bacterial re-working of the newly deposited peat and a direct contribution of marinederived lipids at the top of the seam. Fluctuations in n-alkane and isoprenoid distributions and abundances elsewhere in the seam indicate that the depositional environment changed periodically.

On 27th November, 1939 Shell was awarded its first exploration concession in Australia. The initial holdings covered much of southern Queensland, including parts of the Eromanga, Surat and Bowen Basins. An exploration programme involving field geology, aerial photography, a gravity survey and shallow structural drilling preceded a 'deep test' in 1950, Morella-1, located in the Denison Trough near Springsure. In the course of the venture, Shell was responsible for the first effective application of several modern techniques to petroleum exploration in Australia, including geophysics, organic geochemistry and wireline logging. Although disappointing results led to relinquishment of this first area, Shell has continued to explore in Australia, initially through participation in the WAPET and North West Shelf consortia, and from 1962 in a series of other ventures throughout the country. The rewards, in terms of Shell equity reserves, total some 1.7 billion barrels of oil equivalent at an exploration cost since 1964 of 1.1 billion dollars (1988 equivalent value).
