The remaining potential offshore Congo is unlocked by a quantitative interpretation of our large MegaSurveyPlus dataset. The geology of the region is revealed beyond block boundaries, enabling new insights into the petroleum systems, play fairways, and analogous discoveries. Opportunities can now be analyzed in reliable prestack detail down to prospect level, to improve investment decisions.

Offshore Congo’s proven pre and postsalt petroleum systems have been generating oil and gas for over 50 years. The area has been extensively covered with 3D seismic data. However, the data was acquired piecemeal, with a focus on specific targets, and without the regional context required to fully comprehend leads in their wider setting.

SNPC partnered with PGS to repair this fragmented view. The Congo MegaSurvey, matched and merged final full-stack data from many legacy volumes to create 22 415 sq. km of 3D data, 5 331 km of matched 2D seismic data. They then added regional interpretation with key horizons tied to released well data.

In 2019, that coverage was enhanced by MegaSurveyPlus reprocessing of 3D data across nearly 9 000 sq. km of open and held acreage.
