Shallow Water Tano exploration well update

Source: www.gulfoilandgas.com 10/9/2007, Location: Africa

Tullow Oil plc announces that the 1N-3X appraisal well in the Shallow Water Tano block has been drilled to a total depth of 3,075m. Following the results of logging operations the well will not be flow tested. The 1N-3X well tested a previously undrilled fault block in this near-shore shallow water licence. The objective was to determine if modern drilling techniques, designed to reduce formation damage, could be used to achieve commercial flow rates from the low permeability Albian reservoirs encountered in previous wells. Hydrocarbon bearing sandstones were encountered in this well but logging results indicated that the sandstones would not flow at commercial rates. The well has therefore been plugged and abandoned.

Future operations in Shallow Water Tano will continue to focus on further appraisal of existing discoveries and delineation of exploration prospects in this block, which is updip of Tullow’s recent Santonian reservoir discoveries, Mahogany and Hyedua. These discoveries were made in June and August this year in the adjacent Deepwater Tano and West Cape Three Points licences.

Tullow (31.5%) operate Shallow Water Tano on behalf of partners Interoil (31.5%), Al Thani (22.5%), Sabre Oil and Gas (4.5% carried) and GNPC (10% carried).

Tullow is also the operator of the Deepwater Tano licence (49.95%) and a partner in the West Cape Three Points licence (22.9%).
