High wax crude oils are generated from organic matter derived from either land plants or freshwater algae. The Cambav crude oils are oroduced from a rift basin and the oils in-the northern fields of the Cambay Basin are sourced from the Cambay black shale. In this paper the effect of the envi- ronment of deposition of the source rock on the nature of crude oils derived from type III organic matter is reported. Source rock extracts which have not been affected by migrational and post-accumulation changes are used to illustrate this effect.

95lOO146 Extensive alblte dlrsolutlon In Trlasslc reservoir sandstones from the Gannet flsld, UK North Sea Purvis, K. Marine & Pefroleum Geology, Oct. 1994, 11, (S), 624-630. Diagenetic albitization of detrital plagioclase and K-feldspar has been reported in several reservoir sandstones of various ages and from different depositional environments from the North Sea. Saigal et al. (1992) sug- gested that the degree of albitization of detrital feldspars in the Upper Jurassic Fulmar Formation can be used as an indication of the timin of hydrocarbon charge in the reservoir, with albitization being arreste d by hydrocarbon migration. This paper presents the results of a petrographic study on the reservoir sandstones from the Triassic Skagerrak Formation.

Marshall, J. E. Marine & Petroleum Geology, Oct. 1994, 11, (5), 631-636. It is now generally accepted that during the early fragmentation of West Gondwana several microplates separated from Africa and Antarctica. Among these microplates was the Falkland Platform, which was displaced from its original position against the east coast of southern Africa, rotated by 120” and ultimately became an extension of the continental shelf of southern South America. The paper considers both the implications of the extensional origin of the Falkland Plateau Basin for the timing of hvdrocar- bon generation-and shows how the microcontinental movem&rt of-the Fal- kland Platform introduces a ‘South African’ exploration play based on Permian hydrocarbon source rocks.

Reports that the concrete work is now finished on the base of the Troll East gas platform, and events are accelerating towards the mating of this sup- port structure and the 22,500t deck it will carry. The operation is scheduled for January. The Troll East is the tallest concrete gravity platform - 370m from the tips of its seabed skirts to the top of its four towers.

95tOOl60 Petroleum gsneratlon and mlgratlon In the Styrlan Basln (Psnnonlsn Basln system, Austria): An Integrated goo- chemical and numerlcal modrlllng study Sachsenhofer, R. E. Marine & Petroleum Geology, Dec. 1994, 11, (6), 684-701. Source rock analysis and numerical modelling techniques have been applied to evaluate the hydrocarbon potential of the Styrian Basin. Oil- and gas-prone sediments occur in the lower Miocene section. The numerical modelling of petroleum migration provides important information on its timing and pathways and predicts correctly the only drilled hydrocarbon occurrence in the Styrian Basin. The calculated gas to oil ratio is 0.5. The integration of all these data helps to define areas with high petroleum potential.

95lOO162 Role of overpressurss and In situ stresses In fault- controlled hydrocarbon mlgratlon: A case study Grauls, D. J. and Baleix, J. M. Marine & Petroleum Geology, Dec. 1994, 11, (6), 734-742. Faults and major fracture networks play a significant part in the transitory dynamics of fluid transfers. A certain number of anomalies induced by these transfers and encountered at shallow depths can be explained only by the active movement of large amounts of fluids from deeper zones, which, moreover, occur over very short geological times. These ideas are con- firmed in the case study presented in this paper, which is based on the analysis of well data from sonic compaction profiles, pressures, in situ stresses and temperatures. This multidisciplinary analysis will help to demonstrate the resence of anomalies related to the nature of the fluids, the pressures an B the temperatures associated with these transfers.
