Summary Shale rocks are very significant for both unconventional and conventional hydrocarbon exploration and exploitation. The main constituents of shale are mica and clay minerals (which occupy 30–90% in volume fraction) and the remaining constituents are quartz, feldspar and carbonates. The orientation distribution of the clay minerals including mica significantly affects the elastic velocities and anisotropy of shales. For any type of rock physics modeling or anisotropy analysis, individual elastic moduli of clay minerals, their orientation distribution functions (ODF) and their volume fractions are imperative. The clay minerals are generally finegrained and it is not possible to find a single large enough crystal for acoustic measurements. In this study, we use the orientation distribution data from published literature to devise an elliptical heuristic function relating bedding-normal P- and S-wave velocity in zero-interparticle-porosity clay aggregates to their preferred orientation. Then we compute elastic moduli for the most common phyllosilicate shale minerals such as muscovite, illite and illite/smectite aggregates. These results can be used for velocity modeling and accurate reservoir property estimations from seismic.

Summary Delaware Basin is one of the most prolific oil and gas basins in North America. The most drilled targets in the basin are Avalon, Bone Springs and Wolfcamp formations. The main constituents of these formations are a heterogonous mixture of organic mudrocks, siliciclastics and carbonates. Due to the complex nature of these lithologies, it is necessary to perform an integrated workflow to extract finer details from seismic to understand and characterize the unconventional targets. In this study, we show a thorough petrophysical analysis and then establish relationships between petrophysical properties of the rock (such as porosity, minerology, pore geometry, and total organic content) to the geophysical measurements (elastic properties) and show geomechanical analysis for Avalon mudrocks and the Bone Springs formation. This integrated workflow serves as a foundation for extrapolating the well data into a 3D reservoir characterization using seismic inversion. Finally, the results can help in searching for sweet spots and decisions on landing, fracking zones for optimal production.
