Fields in the Upper Assam-Arakan Basin have been studied intensely to find prospective sweet spots, perforation intervals for new wells, and potential workover candidates. These forecasts, guided only by dynamic-numerical-model results, have had mixed results when implemented in the field. A validation of the dynamic-model forecasts with near-wellbore-saturation logs can help reduce uncertainty. The validation was carried out in old wells, which helped in making informed decisions about tapping bypassed hydrocarbon pockets.
Introduction
An integrated seismic-to-simulation study was conducted on 42 reservoirs in 375 km2 of the Upper Assam Basin.
