TGS, a global leader in energy data and intelligence, has signed an agreement with Tanzania’s Petroleum Upstream Regulatory Authority (PURA) to manage and license the country’s extensive offshore subsurface data. This collection includes 2D and 3D seismic data covering an area of over 132,000 square kilometers.

Tanzania boasts strong play diversity, proven through exploration success across much of the stratigraphy, from Early Cretaceous to Miocene reservoirs. This comprehensive dataset, which includes regional seismic and well data, will enable detailed interpretations of the basin’s evolution and structural history. It will help identify hydrocarbon plays and allow for prospect-specific analysis and mapping of robust trapping configurations. By providing critical insights into the maturity and distribution of source rocks, this dataset will enhance our understanding of the region’s oil and gas potential.

Under this agreement, TGS holds the exclusive rights to license all of Tanzania’s offshore mainland data on behalf of the government. The agreement also grants TGS the authority to conduct future acquisition of new seismic data and to reprocess existing data. Additionally, it includes support for upcoming licensing rounds, which are anticipated to commence in 2025.

David Hajovsky, EVP of Multi-Client at TGS, commented: “Tanzania remains an attractive exploration target with its world-class gas fields and excellent sands proven across multiple source intervals. By providing access to high-quality seismic data ahead of potential future licensing activities, TGS will empower exploration and production companies to evaluate opportunities in this under-explored but highly promising region of East Africa.”
