Prospect definition The prospect relative to the petroleum system and plays. Prospect evaluation: where it stands in the exploration and production process Reserves vs resources Application exercise
Some of the following chapters can be developed or not, according to the geological background of the students. Hydrocarbon charge Source rock types, maturity, HC migration timing, relative to traps HC fluids Fluid properties according to source rock type, maturation and migration PVT conditions Alteration like biodegradation inside the reservoir. Non HC fluids H2S and CO2 Fluid contact determination
Reservoir characteristics. Impact of the depositional environment on the reservoir body geometry and internal architecture Diagenesis influence on reservoir characteristics Seal Top and lateral seal. Fault sealing. Examples Surface seeps as the ultimate migration Trap Trap types; structural: fold and fault related. Stratigraphic and mixed traps. Trap occurrences according to basin types Examples
Calculating the oil or gas prospect resources using the gross rock volume, net/gross ratio, average porosity, hydrocarbon saturation, formation volumetric factor, and recovery factor. Depth dependent gross rock volume Introduction to uncertainties, affecting the different parameters used for the resource computation, with a specific focus on the gross rock volume Probabilistic approach Differences between risk and uncertainties. Basics of statistical concepts like the Monte Carlo simulation Results of probabilistic volume assessment and their graphic representation – Application exercise
How to make the risk evaluation based on 5 geological parameters: Source rock, hydrocarbon charge, and migration, reservoir, seal and trap Multi objective prospect How to cope with multi-objective prospect for evaluating the global risk Risk dependency for multi objective prospect Post mortem evaluation after the exploration well Prospect port-folio management Conclusions and recommendations Quiz
