... core-based measurements can be inconsistent and inaccurate when evaluating clay minerals and other grain constituents. We introduce a new method for organic-shale evaluation based on well logs to estimate total porosity, total organic carbon (TOC) and volumetric/weight concentrations of mineral/fluid...

..., a more detailed petrophysical rock model should and has been considered by various authors (Fertl et al. 1988). We extend evaluation in two areas—evaluation of the rock in terms of its mass constituents and pore space, and detailed application of the particular features of magnetic resonance logs...

... transform, built from a database of live oil samples collected in heavy oil reservoirs, is used to compute macroscopic viscosity from the relative volume fractions of the constituents. The methodology is designed for real-time heavy oil applications in carbonates and is unique in several ways. Most...

... for the combination of two porous constituents. This allows to compute the dry frame bulk modulus (Kd) for dispersed shale in sandstone matrix. Its interpretation with Vp/Vs clearly indicates under-estimation of dry frame moduli in hydrocarbon bearing zone. The study establishes a general relationship between shear...
