Abstract

Estimates of reservoir properties such as porosity, TOC content, clay content, fluid saturation, and fracture intensity are required for understanding unconventional reservoirs. The porosity and TOC content help to explain the reservoir quality; natural fracture intensity provides information important to the completion strategy. In this case study, an orthotropic rock physics model integrating well and core data was established. This study assumes a vertical transverse isotropic (VTI) kerogen-rich layer, containing swarms of aligned vertical fractures. Prestack orthotropic AVAZ inversion results were used to predict porosity, TOC, fracture density, and fracture orientation using this rock model.
