Zanzibar has entered a critical phase in its quest to unlock offshore oil and natural gas resources following the signing of a major seismic data acquisition contract by the Zanzibar Petroleum Development Corporation (ZPDC).
The agreement, signed on Saturday, paves the way for the collection of advanced 3D seismic data in Unguja, a move officials say will significantly improve understanding of the islands’ subsurface geology and boost investor confidence in Zanzibar’s energy sector.
ZPDC Managing Director Mikidadi Ali Rashid formalised the deal with Africa Geophysical Services (AGS) General Manager, marking a key milestone in Zanzibar’s long-term hydrocarbon exploration strategy. The seismic survey will generate high-resolution data crucial for identifying potential oil and gas reserves both offshore and onshore.
Speaking after the signing, ZPDC officials said the new data would build on earlier 2D surveys and help de-risk future exploration activities by providing clearer geological insights. This, they added, positions Zanzibar more competitively in attracting international exploration and production companies.
“The acquisition of 3D seismic data is a game-changer for Zanzibar’s oil and gas ambitions,” said a senior ZPDC official. “It strengthens our technical capacity, enhances transparency, and lays a firm foundation for informed licensing and investment decisions.”
The project is also expected to create opportunities for skills transfer, with local professionals working alongside international experts during data collection and analysis. Authorities say this aligns with Zanzibar’s broader goal of ensuring that natural resource development contributes directly to local capacity building and economic growth.
Zanzibar’s push into oil and gas exploration comes as part of wider efforts to diversify the economy, reduce dependence on tourism, and expand domestic revenue sources. If commercially viable reserves are confirmed, the sector could play a transformative role in funding social services, infrastructure, and long-term development.
The seismic survey is expected to begin in the coming months, with results guiding the next phase of exploration and potential licensing rounds. As the project moves forward, both government and industry players are watching closely, viewing this phase as a decisive step toward determining Zanzibar’s energy future.
