A recent data interpretation operation by ARA Petroleum Tanzania has revealed some exciting news about the Ruvuma PSA. A 3D survey conducted by Aminex has shown a significant increase in resource potential in the wider license area. This survey has uncovered 338 sq km of new data, leading to some promising results.
Through seismic inversion geomodeling with Ikon Geoscience, there has been a notable improvement in the in-place volumetrics for the Ntorya gas discovery. It is estimated that around 3.45 trillion cu/ft of gas initially in place (GIIP) could be found in the reservoir sandstones of the Ntorya-1 (NT1) and Ntorya-2 (NT-2) discovery wells.
Potential Future Discoveries
The new 3D seismic images suggest the presence of even more gas-charged reservoir sandstones, potentially leading to additional gas volumes. There is also hope for the discovery of an as yet undrilled shallower sand unit (Unit 3) to be tested by the upcoming Chikumbi-1 (CH-1) appraisal well.
Exploration Potential
For the first time, the 3D dataset has uncovered significant undrilled exploration potential within the broader license area. This opens up new possibilities for future discoveries.
Excitement from Executives
Charles Santos, executive chairman of Aminex, expressed his excitement about the results, stating that the Ntorya gas field development is reaching important milestones. The new 3D seismic dataset has provided detailed mapping of the Ntorya gas discovery, refined volumetric estimates, and identified future drilling targets. The potential gas volumes identified in other untested structures within the license area are particularly exciting.
The discoveries in the Ruvuma PSA are promising and could lead to significant developments in the gas industry in East Africa. Stay tuned for more updates on future drilling programs and commercialization plans for these exciting opportunities.
