Mandawa
The Mandawa PSA is a sparsely-populated area along the Tanzanian coast. The Early Jurassic Mandawa sedimentary basin – the target of Dominion’s exploration activity – includes source rocks capable of generating oil, sandstones and limestones that are potential reservoir rocks, and a number of potential oil traps. Structural traps are provided by salt movement and basement faulting. Dominion intends to drill the first commitment exploration well – Mihambia-1 – in late 2008. The well will be drilled to a total depth of between 2,300m and 2,800m to an Early Jurassic target. Dominion working interest 50%; partner: Maurel & Prom (50%).

Kisangire
The Kisangire PSA comprises two large, adjoining licences: Kisangire and Lukuliro. To the east of the area is the Songo Songo gas field, which supplies gas for power generation in Dar es Salaam. The Mkuranga gas discovery (Maurel et Prom, 2007) lies just outside the Kisangire Licence. In Kisangire, the earlier Permian Selous sedimentary basin plunges beneath the Jurassic Mandawa basin and the area includes both Permian and Jurassic targets. There are oil seeps in the centre of the Kisangire Licence at Wingayongo. A seismic programme (approximately 250 km) is planned for 2008-9 and exploration drilling is anticipated to start in 2009. Dominion working interest 45% (operator: Heritage Kisangire Tanzania Limited).

Selous
The Selous PSA in southern Tanzania is a relatively un-explored area dominated by the Permian Selous basin. Following an initial technical evaluation, Dominion considers that there is potential for oil and gas in the area and that additional seismic data will identify significant prospects. Seismic acquisition will not start before 2009 due to environmental constraints. Dominion working interest 100%.
