MAURITANIA OFFSHORE DRILLING UPDATE: (28-10-2005)



ROC advises that the following release was made earlier today by Woodside Petroleum Ltd. ROC further advises that evaluation operations are incomplete and ROC will issue an update upon completion of those operations.

 


“Woodside Mauritania Pty. Ltd., a wholly-owned subsidiary of Woodside Petroleum Ltd., reports the following activity in offshore Mauritania since the last report issued on 25 October 2005.

 

PSC Area B: Tevét- 2 and Tevét-2 ST1 Combined Appraisal and Exploration Well
Combined Appraisal and Exploration Welll

The ‘Stena Tay’ drill rig is progressing wireline logging operations of the Cretaceous exploration objective of the Tevét-2 sidetrack (ST1).

A preliminary evaluation of wireline log data, including fluid sampling and downhole pressure measurements, has established that the exploration well intersected a gross oil interval of approximately 8 metres in good quality sandstones.

While the hydrocarbon column is small and may not prove to be material, the result is encouraging for future Cretaceous exploration targets in Woodside-operated Mauritanian acreage.

Once logging is completed the well will be plugged and abandoned as planned and the ‘Stena Tay’ will move to the Labeidna-1 well location.

 

General

All reported drilling depths are referenced to the rig rotary table and all times are Universal Time (UTC) (Mauritanian time).

The locations of planned exploration wells and the Chinguetti Oil Field are shown on the attached map."

Exploration Drilling

The exploration well, Flying Foam in WA-327-P is scheduled to commence drilling on or around 30 October 2005. The well is planned to be drilled to a total depth of 1,431metres and will take approximately 10 days to drill the well.

 

Cliff Head A Installation and Development Drilling

Following the drilling of Flying Foam, the Rig will move to WA-286-P to be used to install the Cliff Head A production platform following which it will commence drilling of production wells.

In early 2006, the Rig will be used to lift the platform topsides into position. Development drilling will then recommence and continue until all the development wells are completed.

Following the completion of Cliff Head development drilling the Rig is planned to undertake further exploration drilling in the offshore Perth Basin which includes the drilling of Frankland-1 in WA-286-P.

DRILLING PROGRAMME UPDATE - OCTOBER 2005- MARCH 2006: (06-10-2005)



Further to the 27 September 2005 Open Briefing, ROC advises that the majority of its Drilling Programme for the period October 2005 - March 2006 remains unchanged including the 7-8 Cliff Head Development wells plus platform installation.



The attached updated Drilling Programme includes the following modifications:

Up to 12 exploration/appraisal wells are now scheduled to be drilled during the period.

Two of the 12 exploration/appraisal wells (Equatorial Guinea and New Zealand) may be subject to further delays due to rig availability.

Two development wells for the Blane Oil Field are now scheduled to commence January 2006.

Any changes to the Drilling Programme will be updated accordingly.
