Due to the annual commemorative march in Athens on 17 November, if you plan to take one of the pre-conference short courses you are strongly encouraged to book your stay at the Hotel Divani Caravel, where the courses will be held.
Post-ConferenceExploration geologists and geochemists who use geophysical, stratigraphic and geochemical data to evaluate the oil and gas potential of sedimentary basins.
Petroleum System Analysis (PSA) is a practical approach to evaluate the probability that a basin has the necessary prerequisites to generate, charge, accumulate and preserve economic amounts of hydrocarbons and that the timing of the processes is favourable. The principal elements of petroleum systems such as source rocks, effective migration pathways, traps and seals are identified and measured using geophysics and geochemistry. The application of multidimensional modeling adds the hydrocarbon charge and timing aspects to exploration risk assessments.
The course provides a tour starting with conceptual models and alternative scenarios of basin evolution. Participants will examine what helpful data are available in the public domain and specialized libraries, such as heat flow, rock properties, etc. Burial and thermal history models will be built and calibrated by measured data with case histories from rift, passive margin and foreland basin settings. Participants will practice building and modifying his model. Examples will be shown how to achieve the best combination of a mathematical with a geological model. Short excursions to geothermics, source rock depositional environments and geochemistry will demonstrate the effects of this information on the calculated petroleum potential. Special attention will be given to kerogen kinetics and how they are measured and incorporated in a model to address questions such as why we might find more condensate instead of oil in some basins.
Once the active generation kitchen is delineated, fluid flow will be simulated using different tools, such as migration pathways tracing or invasion percolation. Participants will have the opportunity to check gas/oil ratios using new tools for PVT simulators and flash calculations for different reservoir depths and to predict the composition of the liquid and vapour phases as the fluids migrate through the basin or are extracted to the surface. Finally, risk analyses will show how much the uncertainty of specific types of input data can affect the resulting prediction and prospect appraisal.
This short course with exercises will show how modeling the dynamics of the petroleum system makes it easier for geoscientists to evaluate the impact of different charge scenarios on their exploration risk assessments and resulting exploration decisions.
