Summary
The first time that a comprehensive regional dataset encompassing offshore Tanzania has become available. Analysis of this dataset provides fresh perspectives on undeveloped gas fields discovered during the mid-2010s and highlights additional opportunities within Palaeogene and Cretaceous deep-water marine sandstone reservoirs. Furthermore, the data enable assessment of higher-risk, frontier plays that remain largely untested. This evaluation draws on an extensive collection of legacy 2D and 3D seismic surveys of varying vintages, totalling approximately 53,000 km of 2D lines and 27,300 km² of 3D coverage, supplemented by data from six offshore wells. Interpretation of these data sheds light on the margin’s tectonic and depositional history and identifies prospective targets in both established and frontier plays.
