The 326-line km of high resolution 2D seismic data acquired over the KON-16 block provides clear imaging of key pre-salt structures increasing confidence that the acquisition will lead to multiple derisked pre-salt and post-salt drilling opportunities within KON-16, said Corcel.
Seismic processing by DUG will follow with results expected throughout the year to support prospect maturation and drilling preparation.
‘The initial field data shows the positive impact of the high specification acquisition parameters designed specifically to image the high-graded pre-salt prospects in KON-16, advancing prospect definition and supporting the company’s progression towards drilling the high-impact KON-16 exploration well,’ said Corcel in a statement.
The onshore Kwanza basin has 2589 line-km of 2D data acquired in 2010 and reprocessed in 2025. Over KON-16 there are 143 line-km of 2D data. Acquiring 326 line-km of new 2D data provides a 227% increase in seismic coverage inside KON-16, which will greatly increase the subsurface imaging, prospect definition, and decrease exploration risk, said Corcel.
Current modern 2D line spacing averages >14 km in the areas of interest, and while this is sufficient to identify prospectivity, especially when integrated with the eFTG (high-resolution gravity gradiometry) data acquired in 2024, a closer 2D line spacing of 2.5 km was achieved, which is beneficial when moving on to drilling, said Corcel.
The seismic campaign was designed to cover specific prospects high-graded by the Corcel team and to build on the work done in 2025, integrating the legacy 1970s 2D data, the 2010 2D seismic data (which was recently reprocessed), and the 2024 eFTG data.
Raw data is ‘excellent’, said BGP.
