  Information - ERE6 Organic matter composition and source rock potential assessment

Event Information
A crucial part of petroleum exploration strategy is to evaluate the quality of kerogens because this is the key to determining both the quantity and type of petroleum generated, and the extent of this generation within the basin. Surprisingly, despite the availability of more and more analytical tools, the inferred source rock generative profile is never used considering the depositional history of the region, while the source rock quality is genetically tied to the geological context at the time of deposition, since this latter governs the source and the deposition and the preservation of the organic-rich sediments.

The aim of this session is to highlight the importance of organic matter composition and distribution in source rock potential assessment. The following topics will be tackled:
- the relationship between depositional environment and organic matter composition/preservation,
- the relationship between kerogen composition and the type of petroleum generated and generation timing,
- the fate of specific organic debris or kerogen mixture with maturity (variations of optical properties, shape and type of petroleum generated)
- causes of lateral and vertical (temporal) variations of organic composition within the source rock and the subsequent variations of petroleum potential (climatic, tectonic, environmental… causes).
