Abstract

The present study deals with two different fields of Cambay basin. The complex geological environment in the fields, has resulted in abrupt facies variations. Presence of thick coal above reservoir facies also reduces the ability to quantify reservoir properties and its extension. Simplistic reservoir models may not be able to capture the finer details in such environments. To address these challenges, detailed reservoir characterization has been performed. To identify geo-bodies, facies boundaries and geomorphological features, targeted seismic attribute analysis, waveform classification and inversion was carried out. In the first case study, a channel system at K-X/XI pay level has been identified.
