In March 2007, Dominion Tanzania Limited - a wholly-owned subsidiary of Dominion Petroleum - signed a Production Sharing Agreement which grants rights to explore for petroleum in the offshore Block 7. Block 7 is located on the continental slope of the Indian Ocean, immediately east of Dar es Salaam and incorporates 8,492 square kilometres (2.10 million acres). Water depths in Block 7 range from less than 400m to more than 2,500m.

In 2007-2008, Dominion acquired 4,350 km of 2D seismic over Block 7. Initial interpretation of the data indicates the presence of substantial leads in moderate water depths. Following further interpretation, 3D seismic will be acquired over selected leads. During 2008-2009, Dominion will participate in a Metocean survey in a consortium of offshore Tanzania operators led by Statoil. This survey will provide important information for the selection of drilling sites and for well design.
