Orca Exploration's mission is to benefit our shareholders, employees and partners through the exploration and development of oil and gas resources in proven underdeveloped hydrocarbon basins.

Orca Exploration is an international public company engaged in hydrocarbon exploration, development and supply of natural gas in Tanzania and oil and gas exploration in Italy. Orca and its employees are committed to ethically, socially and environmentally responsible development.

Orca Exploration Group Inc. operates the 879 Bcf Songo Songo natural gas field under a Production Sharing Agreement (PSA) with the Tanzania Petroleum Development Corporation (TDPC). 195 Bcf is allocated for use by Songas Limited and 684 Bcf is produced, marketed and sold by Orca Exploration. The license has a total area of approximately 41,630 acres (170 km2). The blocks are located in shallow water approximately 15 kilometres off the coast and 200 kilometres south of Dar es Salaam. The license contains the large Songo Songo gas field which is positioned on and slightly offshore Songo Songo Island. The main reservoir is developed in Lower Cretaceous aged Neocomian to Albian sandstones (Neocomian), while Upper Cretaceous aged Cenomanian sands that lie unconformably on the Lower Cretaceous provide additional reservoir when developed.

As at 31 December 2011 the independent reserve evaluator, McDaniel and Associates Consultants Limited, assessed the Additional Gas proven (1P) and proven and probable (2P) Songo Songo reserves available to Orca to the end of the licence period at 469 Bcf and 584 Bcf respectively.  Orca management estimates that the total Mid Case reserves (Protected Gas plus Aditional Gas) from the Songo Songo Field and the Songo Songo North discovery is 1,079 Bcf as at 31 December 2011.

Orca operates a gas processing facility on Songo Songo Island on behalf of Songas Limited, the gas processing facility owner, on a no loss, no gain basis. The plant supplies natural gas to a 25 km 12” marine pipeline and a 207 km 16” land pipeline that extends north along the coast to Dar es Salaam. Songo Songo is Tanzania’s first natural gas development.
