Corcel completes seismic acquisition in Kwanza basin
Corcel plc completed the 2D seismic acquisition project at KON-16 block within Kwanza basin, onshore Angola, and said the dataset provides clear imaging of key pre‑salt structures, giving it increased confidence in advancing multiple de‑risked pre‑salt and post‑salt drilling opportunities.
The 326-line km of 2D seismic was acquired throughout December 2025 and first-quarter 2026, with acquisition concluding on Feb. 22, 2026. Initial internal review of the raw field data shows excellent data quality, superior to previous seismic acquired in the Kwanza Basin to date, Corcel said.
Kwanza basin has 2,589 line-km of 2D data acquired in 2010 and reprocessed in 2025. Over KON-16 specifically, there are 143 line-km of 2D data. Acquiring 326 line-km of new high quality 2D data provides a 227% increase in seismic coverage inside KON-16 which is expected to increase the subsurface imaging, prospect definition, and decrease exploration risk, the company said.
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, the company continued.
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.
Corcel is operator of KON-16 with 71.5% net interest.
