In an agreement with the Office National des Pétroles (ONAP), WesternGeco has reprocessed part of the GWG99 survey data, specifically targeting the open blocks over the shelf areas of offshore Guinea. This has resulted in a high-quality prestack time migrated dataset with a significant uplift on the original data, providing new geological knowledge of the region. All final deliverables are now available including prestack and inversion ready products which will provide critical insights in the evaluation of regional prospectivity.

Key reprocessing highlights include

• advanced noise attenuation
• adaptive deghosting
• advanced cascaded multiple attenuation
• prestack time migration
• full suite of AVO and inversion-ready products.
