TGS has announced the completion of the reprocessing of the Block 16 GeoStreamer MC3D seismic dataset in Angola’s Lower Congo Basin, in partnership with Agência Nacional de Petróleo, Gás e Biocombustíveis (ANPG).
Exploration in the deepwater Lower Congo Basin has experienced a resurgence in recent years, with numerous significant discoveries being made and rapidly brought on stream. This 3,684-square-kilometer rejuvenation project utilizes modern depth processing workflows to deliver enhanced imaging beyond the original data, enabling detailed evaluation of deeper target plays in both post-salt and pre-salt sections.
Angola’s Block 16 has remained largely underexplored since the early 2010s, with the most recent exploration well drilled in 2013. Until recently, publicly known oil and gas discoveries within Block 16, as imaged by this dataset, were limited to the Bengo (1994) and Longa (1995) Upper Miocene finds in the northern section. However, a recent re-evaluation of wells in the Lower Congo Basin has identified oil recovery from Upper Miocene reservoirs in the southern part of the survey area.
The survey also provides partial coverage of the Tchihumba Field, a marginal field development opportunity currently being marketed by ANPG. Discovered in 2003, Tchihumba contains hydrocarbon-bearing zones within Upper Miocene, Lower Miocene, and Oligocene sands, with recoverable volumes estimated at approximately 136 million barrels. Additionally, the Lumpembe-1 oil discovery on Block 15/06, drilled in 2023 and currently undergoing development studies, falls within the survey’s extent.
David Hajovsky, Executive Vice President Multi-Client commented on the project, 'TGS is very pleased to continue our support of exploration in this region with our high-quality seismic data. These accumulations, along with the proximity of significant neighboring discoveries, present strong opportunities for future exploration success.'
Final depth-migrated deliverables are now available. For more information or to arrange a data viewing, please contact amme.info@tgs.com.
