Tod (BP) SUMMARY The Tiguentourine field is located in the southern part of the Illizi Basin in eastern Algeria and is operated by the In Amenas Association a joint venture between BP Sonatrach and Statoil. Ordovician-aged hydrocarbon reservoirs in the Illizi Basin consist predominantly of tight clastic rocks with a complex depositional history. Production data suggests that open fractures may play an important role in determining individual well productivity. In 2004 a
