Unravelling Seismic Dim Zone for Reservoir Characterization with Advanced Geophysical Analysis to Unlock Petroleum Potentials

A comprehensive technical evaluation with geophysical analysis was conducted after the completion of a recent exploration and appraisal drilling campaign to assess the future petroleum potentials in B Field, located in West Luconia Basin, offshore Sarawak.

Understanding of seismic dim zone with the full integration of seismic interpretation, seismic inversion, JiFi and AVO modelling with integration of well data, MDT pressure data, has resulted in an improved understanding of reservoir distribution, and reduced the degree of uncertainty in reservoir connectivity, thus unlocking new petroleum potentials and allowing a more robust development strategy.

This paper focuses on major discoveries, reservoirs of the Upper Cycle V, Sand X and Sand Y, with findings from key wells, namely Well-B2 and Well-B2ST1, using AVO modelling and seismic inversion, with well logs and MDT pressure data integration to better understand the petroleum potential for subsequent development planning.
