Targeted vs. regional model building and imaging. A case study from offshore Sabah Malaysia

MC3D velocity building and imaging using conventional tomography tools is regional in scope and fit for purpose for exploration. However, reprocessing and imaging using higher end applications will provide significant uplift provided the underlying seismic data is acquired and pre-processed to a standard that supports the hi-end applications. Detailed velocity, Q and anisotropic models were the key in this survey to properly image and de-risk a potential prospect. The information extracted from the migrated image but also from the high-resolution updated models can be later used for in-depth analyses including targeted structural interpretations, seismic inversion and quantitative studies.
