Paper Number: SEG-2021-3583577
... different from those in conventional rocks. Source rock properties are difficult to measure, understand, and simulate because of their nanoscale heterogeneities, low porosity, and tiny pore-sizes. We focus on elastic characterization of the soft organic component of source rocks, that typically occurs...
