TL;DR: In this paper, an inversion-based method for in situ evaluation of organic shale from conventional well logs is proposed. But the method is limited to estimating the total porosity, total organic carbon (TOC), and volumetric/weight concentrations of mineral/fluid constituents.
Abstract: Reliable estimates of petrophysical and compositional properties of organic shale are critical for detecting perforation zones or candidates for hydro-fracturing jobs. Current methods for in situ formation evaluation of organic shale largely rely on qualitative responses and empirical formulas. Even core measurements can be inconsistent and inaccurate when evaluating clay minerals and other grain constituents.We implement a recently introduced inversion-based method for organic-shale evaluation from conventional well logs. The objective is to estimate total porosity, total organic carbon (TOC), and volumetric/weight concentrations of mineral/fluid constituents. After detecting bed boundaries, the first step of the method is to perform separate inversion of individual well logs to estimate bed physical properties such as density, neutron migration length, electrical conductivity, photoelectric factor (PEF), and thorium, uranium , and potassium volumetric/weight concentrations. Next, a multilayer pe...
TL;DR: Leviticus has an edifice complex. Reflecting the architecture of the tabernacle, the book is much more than a stern recitation of the dangers of impurity.
Abstract: Leviticus has an edifice complex. Reflecting the architecture of the tabernacle, the book is much more than a stern recitation of the dangers of impurity. With chapter 19 as its apex, Leviticus is about justice and love in the community of faith. Indeed, its relevance in Jesus' ministry may surprise Christians.

TL;DR: The primary objective of seismic exploration in a hard rock environment is the detection of heterogeneities such as fracture zones, small-scale geobodies, intrusions, and steeply dipping structures that are often associated with mineral deposits as mentioned in this paper.
Abstract: The primary objective of seismic exploration in a hard rock environment is the detection of heterogeneities such as fracture zones, small-scale geobodies, intrusions, and steeply dipping structures that are often associated with mineral deposits. Prospecting in such environments using seismic-reflection methods is more challenging than in sedimentary settings due to lack of continuous reflector beds and predominance of steeply dipping hard rock formations. The heterogeneities and “fractal” aspect of hard rock geologic environment produce considerable scattering of the seismic energy in the form of diffracted waves. These scatterers can be traced back to irregular and often “sharp-shaped” mineral bodies, magmatic intrusions, faults, and complex and heterogeneous shear zones. Due to the natural lack of reflectors and abundant number of diffractors, there are only a few case studies of diffraction imaging in hard rock environments. There are almost no theoretical models or field examples of diffracti...
