Source rock modeling
Source rock: the first key element of a petroleum system
In oil and gas exploration, the petroleum potential of a source rock, generally characterized by its thickness and its total organic carbon (TOC) and hydrogen index (HI), is of primary importance. Therefore, explorationists must estimate the distribution of richness (TOC and HI) of source rocks. During operational petroleum exploration projects, this is generally obtained from scarce field data (e.g. well data or outcrop) and then mathematically extrapolated (e.g. simple kriging or smoothing methods) to the whole basin hardly including the available geological information. If these methods can prove to be useful, but not always satisfactory for accurately identify sweet spots, for unconventional resources as many wells target the source rocks, this is far to be the case in conventional exploration.
