PSC Area A Sotto-1 Exploration Well
The Stena Tay returned to Mauritanian waters and resumed work on Chinguetti Development wells prior to commencing the 2005 exploration drilling program. The Sotto-1 Exploration Well was spudded on August 6, 2005 in approximately 320 meters of water and drilling continued to 1,146 meters. At midnight on 8 August 2005, 13-3/8 inch casing was being run prior to drilling to the planned total depth of approximately 3,350 meters.
Chinguetti Development Drilling and Banda Gas Injector Well
The West Navigator continues to perform completion work on Chinguetti Development wells. As part of the Chinguetti Development Well program a gas injection well has been drilled into the Banda field. This well is currently being tested by the West Navigator and the well test is progressing as planned. The well has flowed gas at the rate of 32mmscf/d through a 52/64-inch choke, at a surface flowing pressure of 2866 psi during the main flow period. Testing is continuing with a reduced flow rate period for sampling and production logging.
Gas produced in association with the Chinguetti oil production, in excess of the Chinguetti field requirements will be injected and stored in the Banda gas reservoir.
Woodside does not plan to issue regular announcements regarding operations on Chinguetti development wells, but will do so if necessary to comply with its continuous disclosure obligations under the ASX Listing Rules.
All reported drilling depths are referenced to the rig rotary table and all times are Universal Time (UTC) (Mauritanian time).
Wells are expected to be drilled in three production sharing contract areas during the remainder of the 2005 campaign."
