Abstract

Key factors influencing source rock potential are the extent and nature of primary deposition and post-depositional thermal, tectonic and geodynamic history, which will affect the subsequent preservation and maturity of the source rock. We present a global evaluation of source rock potential and risk from the Ediacaran and Phanerozoic. This evaluation is made by combining 52 palinspastically restored gross depositional environment maps with a global plate model for the Phanerozoic and Ediacaran taken from the Neftex Global Earth Model product suite. The 52 palinspastic gross depositional environment maps were produced by taking reconstructed observations and interpreting them regionally based on both the tectonic setting and a predictive sequence stratigraphic framework. When combined with predictions of paleoclimate and paleo-ocean circulation, this framework allows us to predict zones of organic enrichment and source rock deposition through time. Once deposited, the global plate model allows us to identify regions where geodynamic processes (e.g. collision zones, large igneous provinces, rifts) are likely to have influenced source rock preservation and maturity. By combining these data with the observed geology and sediment thickness at the present day, we generate a global risk map of source rock potential that can be used to identify new exploration opportunities,
