... II and the thermal maturity index is 1.28. Based on the hosting element, microporosity in Hanifa Fm. can be categorized into three groups: framework, solid bitumen and intraparticle pores. A key observation of this study is that pore types in Hanifa Formation vary between framework which accounts...

... The elastic frame moduli for the Lower Mt. Simon Sandstone are estimated by accounting for grain boundary compliance and concavity of pores in the vicinity of grain contacts. This sandstone is the target formation for underground storage of CO2 in the Illinois Basin – Decatur Project, a 1...

This work addresses how the distribution of mineralogic composition impacts pore type and their respective volume fraction predictions from a rock physics modeling, by comparing two scenarios for one well log in a Brazilian presalt field. The first scenario considers XRD mineral fraction data...

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...
