"Woodside Mauritania Pty Ltd, a wholly-owned subsidiary of Woodside Petroleum Ltd., reports the following activity offshore Mauritania since the last report issued on 23 November 2004.

PSC-B, Block 4
Tiof-3 ST2, Tiof-4 and Merou-1

Tiof-3 ST2 Appraisal well

The “West Navigator” drill ship is preparing to suspend the Tiof-3 ST2 well as a potential future development well. The production test data acquisition has been limited to various samples and pressure measurements due to operational difficulties. Further production testing of the reservoir will be required during the appraisal campaign.

Merou-1 Exploration well

The “Stena Tay” drilled the Merou-1 exploration well to a final total depth of 3,060 metres.

Evaluation of logs acquired while drilling and wireline logging operations, including fluid sampling and downhole pressure measurements, has established that the well intersected a number of thin gas and water bearing sands. Initial interpretation suggests that the accumulations are sub-economic, but further analysis will be required to determine the full significance of the well results.

At midnight on 29 November the “Stena Tay” was plugging and abandoning the well as planned prior to moving to the Tiof-5 appraisal well location.

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

The locations of the Chinguetti Oil Field, the Tiof and Banda discoveries and exploration wells are shown on the attached map.

Wells are expected to be drilled in two production sharing contract areas during the remainder of the 2004/5 campaign."

As at 28 November 2004, the Errington-1 exploration wildcat well site was drilling ahead in directional hole at 311m towards the next casing point at 700m.

Errington-1 is located in PEDL 028 approximately 35 km west of Newcastle in northern England.

The Errington-1 wildcat exploration well, which is targeting a potentially large gas prospect, is expected to reach the first objective horizon during late December 2004.

PSC-B, Block 4 Merou-1 Exploration Well

ROC advises that the Merou-1 exploration well in PSC-B, offshore Mauritania, has reached Total Depth of 3060m. Drill data and preliminary log evaluation suggest that the well intersected a number of thin hydrocarbon-bearing sands. Hydrocarbon samples have been recovered to surface. Initial interpretation suggests that the accumulations are not of economic size, but further analysis will be required to determine their full significance.

Tiof-3 ST2 Appraisal well

At midnight on 22 November, preliminary activities prior to flow testing the well were underway on the “West Navigator” drill ship. A further announcement will be made when the results are known.

Tiof-4 Appraisal well

Following the successful appraisal results, the well was subsequently plugged and abandoned as planned, and on 18 November 2004, the “Stena Tay” drill rig then moved to the Merou-1 location.

Merou-1 Exploration well

The Merou-1 exploration well was spudded by the “Stena Tay” drill rig on 19 November 2004 in 1,776 metres of water. The 18½ inch hole was drilled to a depth of 2,663 metres where the 133/8 inch casing was set. At midnight on 22 November the current operation was preparing to drill ahead to the target interval.

"Woodside Mauritania Pty Ltd, a wholly-owned subsidiary of Woodside Petroleum Ltd., reports the following activity offshore Mauritania since the last report issued on 9 November 2004.

PSC-B, Block 4
Tiof-4 Appraisal well and Tiof-3 ST2 Appraisal Well

Tiof-4 Appraisal well

The "Stena Tay" drill rig arrived at the Tiof-4 location on 9 November 2004 and drilled the bottom hole section to a final total depth of 2,908 metres.

Evaluation of logs acquired while drilling and wireline logging operations, including fluid sampling and downhole pressure measurements, has established that the well intersected a gross oil column of approximately 113 metres, containing several individual sands of variable thickness. The result was in line with pre-drill expectations.

At midnight on 15 November 2004 the ”Stena Tay" was preparing to plug and abandon the Tiof-4 appraisal well as planned. The "Stena Tay" will then move to the Merou-A location.

Tiof-3 ST2 Appraisal Well

During the week some mechanical problems have resulted in a delay to commencing flow test operations. At midnight on 15 November 2004 the current operation was continuing preparations to flow text the well.

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

The locations of the Chinguetti Oil Field, the Tiof and Banda discoveries and exploration wells to be drilled early in the 2004-05 drilling campaign are shown on the attached map.

Wells are expected to be drilled in three production sharing contract areas during the campaign."

Dr John Doran, Chief Executive Officer of ROC commented that:

"The net oil pay within the overall gross oil column drilled at Tiof-4 lies within the 10% to 40% range established by the other discoveries and successful appraisal wells in the area.

As at 14 November 2004 conductor pipe had been set and cemented at 54 m at the Errington-1 exploration wildcat well ahead of rigging up the ROC-owned Explorer Rig to commence conventional petroleum drilling activities following the release of the air drilling rig which had been used to drill the top hole section.

Errington-1 is located in PEDL 028 approximately 35 km west of Newcastle in northern England.

Preparations to flow test the well continued on the “West Navigator” drill ship.

Capitaine-1A Exploration Well

The “Stena Tay” rig drilled the well to the final total depth of 3130 metres, where wireline logs were acquired.

Evaluation of the logs indicates the well did not contain hydrocarbons, although excellent quality reservoir sands were intersected.

The well was plugged and abandoned, and at midnight on 8 November the “Stena Tay” was moving to the Tiof-4 appraisal well location to drill the bottom hole section.

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

The locations of the Chinguetti Oil Field, the Tiof and Banda discoveries and exploration wells to be drilled early in the 2004-05 drilling campaign are shown on the attached map.

Dr John Doran, Chief Executive Officer of ROC commented that:

"Whenever you embark on a large, multi-well, exploration and appraisal drilling programme in an area that was recently regarded as wildcat frontier acreage, you are going to have a mix of good, bad and indifferent results - its just that, until you drill them, you don't know which wells will be in which category. The result from Capitaine-1A is simply a reminder of normal industry exploration statistics"

KEY POINTS

• Operations have commenced at the Errington-1 exploration wildcat well, onshore UK.

ERRINGTON-1: EXPLORATION WELL, PEDL028, ONSHORE UK (ROC: 100% & Operator)

On 6 November 2004 operations started at the Errington-1 exploration wildcat well located in PEDL028 approximately 35km west of Newcastle in Northern England. The top hole section is being drilled by an air rig but when surface casing has been set that rig will be changed out for a conventional drilling rig.

The Errington-1 well, which is targeting a potentially large gas prospect, is expected to reach the first target horizon during the latter part of December 2004.

Commenting on Errington-1, Dr John Doran, ROC's CEO stated that:

"Like all wildcat exploration wells, Errington-1 is, statistically speaking, likely to be dry with the main risk being poor quality reservoir. However, the Errington structure is very large so that if gas is discovered, the field has the theoretical potential to be even larger than ROC's Saltfleetby gas field in Lincolnshire."

Dr John Doran, Chief Executive Officer of ROC commented that:

"ROC believes that it is now likely that the Mauritanian Government will exercise its entitlement to acquire a 12% interest in the Chinguetti Field Development on a prorata basis from all current Chinguetti participants prior to that entitlement lapsing on 20 November, 2004.
