Abstract
Summary
This study highlights the powerful application of RPTs in quantitatively describing the reservoir properties (e.g., porosity, mineralogical and fluid composition), using the inverted seismic data. Two very different case studies in Saudi Arabia have been presented. In case study 1, the RPT guided the seismic inversion to highlight areas of high effective porosity (i.e., reservoir). Case study 2 described how the RPT and seismic inversion were used to extract geologically reasonable geo-bodies. These geo-bodies were then transformed to a nett-pay map. The nett-pay map identified possible remaining pay zones in an already-producing onshore field.
