Summary:
A rock physics template (RPT) has been constructed using wireline data from six onshore wells penetrating a clean, tight, clastic, hydrocarbon-bearing reservoir of the (early) Permian age within Saudi Arabia. A multi-attribute inversion feasibility analysis suggested that a combination of both acoustic impedance and VP/VS would optimally describe the porosity and shale distribution within the reservoir. The rock physics template was designed to map the zones of higher porosity and variation in shale properties using these inverted acoustic impedance and VP/VS volumes.
