The Delaware Basin is one of the most active drilling areas in the U.S. (Mire et al. 2017). The basin is composed of a complex and heterogeneous mixture of clay rich organic mudrocks, siliciclastics and carbonate sequences from the Avalon, Bone Springs and Wolfcamp formations. Due to the complexity of lithology, it is necessary to extract detailed spatial information about the subsurface to understand the unconventional targets from seismic data. Establishing a good relationship between the petrophysical properties of the rock (such as porosity, minerology, pore geometry, and total organic content) to the geophysical measurements (imaged elastic properties) along with a reliable geomechanical model leads to improved understanding of the reservoir. In this study, we show a workflow that involves the integration of petrophysics, rock physics, geophysics and geomechanics for Avalon mudrocks and the Bone Springs formation. This serves as a foundation for extrapolating the well data into a 3D reservoir characterization using seismic inversion.
