Available Blocks for the Zanzibar
1st Licensing Round

Deep offshore areas from 500m to 3,000m water depth.
A variety of datasets available to licence through exclusive provider, SLB.

Zanzibar Multi-Client Data Library

A variety of datasets from different vintages are available to license through our exclusive data provider, SLB. The majority of the datasets have been processed through depth migration and has available AVO ready products. The data provides valuable insight into the basin’s potential and support the de-risking of the exploration in a largely under-explored basin.

Overview

The offshore Pemba-Zanzibar sub-basin is located along the East African coast, with the Lamu Basin to the north and the Mafia sub-basin to the south. Several exploration wells have encountered oil and gas, and numerous oil seeps across the archipelago point to a functioning petroleum system. This deepwater offshore basin is considered a frontier zone and remains largely unexplored, promising significant exploration potential.

The Development of Zanzibar Sub-Basin

The basin is the result of multiple geological events. Before rifting, the East African craton was part of Gondwanaland. During the Triassic-Jurassic, rifting formed along the East African margin. In the initial stages of rifting, isolated basins were filled with syn-rift lacustrine and restricted marine sediments, considered good potential source rocks. By the Cretaceous, an open marine environment had developed in the basin, and thick packages of sand were deposited. Numerous channels and basin floor fans can be recognised on the seismic, ranging from Lower Cretaceous to Tertiary age with associated structural features, such as, faults/anticlines resulting from basin inversion. The offshore Zanzibar sub-basin is located within the East African Margin that extends from Lamu basin (Kenya) in the North to the Mafia basin (Tanzania) in the South and is bordered from the Indian Ocean to the East and African continent to the West.
