Galoc Field Development - FPSO Reconnection

Galoc Production Company (GPC), the Operator of the Galoc Field offshore Palawan, Philippines, advises that, following disconnection of the FPSO from the Mooring and Riser System which was necessary due to typhoon Frank (FengShen) subsequent inspection of the subsea components by Remote Operated Vehicle (ROV) has revealed damage to one of the upper riser sections. Replacement riser sections have been mobilized from Singapore by our FPSO contractor and have arrived in the field onboard a support vessel for the replacement operation.

The Mooring and Riser System is being recovered and surface inspection and pressure testing of the umbilical will be carried out. The riser replacement and reconnection operations will then be undertaken. An additional vessel equipped with a work class ROV spread has been mobilized to assist our FPSO contractor in completing these activities.

The on-going inspection, reinstatement and reconnection activities involve several delicate, inter-related operations the results of which will influence the timing of First Oil, now anticipated to be early August.

Additional Notes

The Galoc field is located in Service Contract SC14-C (Galoc Sub Block) in 290m of water approximately 65km north west of Palawan in the Republic of the Philippines. The development involves the construction of two subsea completed horizontal production wells, with extended reservoir contacts, tied back to a Floating Production Storage and Offloading ("FPSO") facility via a short seabed pipeline and mid-water riser system. Most likely oil reserves as estimated at time of commitment to the development in 2006, is approximately 10 million barrels. The reserves estimate and requirement for additional wells and facility capacity will be reassessed following an analysis of results from both development drilling and initial field production performance.
