The casing was cemented at this depth but the operational problems have resulted in the top hole being abandoned and the drilling rig, “West Navigator”, moved off location on September 19. The well will be re-drilled in the near future.

Tevét-1

The drill rig “West Navigator” commenced drilling the top hole section of the Tevét-1 exploration well in 489 metres of water on 20 September. At 0000hrs UTC on 21 September, the well was drilling ahead in 17-1/2 inch hole at a depth of 633 metres.

DRILLING ACTIVITY UPDATE: OFFSHORE RIG ARRIVAL IN MAURITANIA SIGNALS START OF DRILLING CAMPAIGN (10-09-2004)

OFFSHORE RIG ARRIVAL IN MAURITANIA SIGNALS START OF DRILLING CAMPAIGN

Roc Oil Company Limited advises that the following ASX Release was made this morning by Woodside Petroleum Limited:

"Woodside Mauritania Ltd., a wholly-owned subsidiary of Woodside Petroleum Ltd., expects the West Navigator to arrive in offshore Mauritania today. The West Navigator is the first of two deep-water drilling rigs that will work in tandem on the 2004-05 drilling program, previously announced on 5 July, 2004.

The West Navigator is expected to begin drilling activities on 11th September. The second drill rig to be used in this campaign, the Stena Tay, is expected arrive around 15 September 2004. The presence of the two rigs allows for “batch drilling” of wells whereby one rig performs the same operation on a number of wells in sequence rather than drilling a single well from top to bottom. The West Navigator will drill the “top hole” sections of a number of exploration and appraisal wells. Following completion of the “top holes”, the wells will be temporarily suspended before the drilling of the "bottom hole" target sections by the Stena Tay. This tandem drilling arrangement utilising the two rigs will achieve increased efficiency during the campaign.

The West Navigator will commence “top hole” drilling of the exploration wells Dorade, Capitaine, Tevet, and the Tiof-A appraisal well. After completing the batch drilling of the “top holes”, the West Navigator will move to completely drill the Tiof-3 appraisal well on the Tiof discovery. This well is currently planned to be completed and flow tested.
The Stena Tay will commence its drilling activities with a development well on the Chinguetti field in PSC Area B, followed by the “bottom holes” on the wells commenced by the West Navigator."

ROC COMMENCES TRADING IN LONDON (07-09-2004)

KEY POINT

ROC, an Australian Stock Exchange ("ASX") 200 company, announces that its ordinary shares have been admitted to trading on the Alternative Investment Market of the London Stock Exchange ("AIM") today under the symbol 'ROC'. Total volume of ROC shares traded on 6 September, the first day of London trading, was 128,829 and the closing price was 74.5p, equivalent to A$1.915 at the current A$-₤ exchange rate of 0.389. Canaccord Capital (Europe) Limited is acting as nominated adviser and broker ("NOMAD") to the Company.



On Monday, 6 September 2004, UK time, ROC released the following comments to AIM:

ROC, an independent oil and gas exploration and production company, has A$100 million net cash, no debt, and produces approximately 3,000 barrels of oil equivalent per day from its 100% owned and operated Saltfleetby Gas Field in Lincolnshire, which is Britain's largest onshore gas field.

The Sydney-based company has a strong operating emphasis and an international focus, with exploration assets in West Africa, China and Australasia and producing and exploration assets in the UK. Each area of activity is associated with a proven petroleum province, two of which were discovered by ROC and its co-venturers. The company has a global acreage holding of approximating 26 million acres/105,000 sq km gross or 4.3 million acres/17,400 sq km net.

The Company has discovered commercial and / or potentially commercial oil with each of its initial wells offshore Mauritania, Australia and China.

During June 2004, ROC operated its first deep water well located in 1,500m of water offshore Equatorial Guinea, West Africa. In total, ROC has drilled, or participated in the drilling of, 37 wells during the last five years with an overall success rate of 62% and an exploration success rate of 33%, based on the 18 exploration wells drilled during this period. ROC's list of current projects includes one new field development (offshore Mauritania) and three potential new field developments (offshore Mauritania, offshore Western Australia and, possibly, offshore China) as well as a possible field development in the UK North Sea.

Over the next six months ROC expects to participate in multi-well exploration, appraisal and development drilling programmes in, around, and on trend from its recent discoveries offshore Mauritania and Western Australia, as well as exploration drilling onshore UK. In total, more than 20 wells are expected to be drilled during this period.

ROC is not seeking to raise any fresh capital as part of its AIM listing because, in May 2004, the company completed a A$92 million fully underwritten, Rights Issue in Australia. The proceeds of that issue will be used to partially fund ROC's development and potential development projects, in Mauritania, offshore Western Australia and, possibly, China, as well as exploration programmes in West Africa, including Mauritania and Angola. A corporate debt facility is expected to fund the balance of the development expenditures.



John Doran, Chief Executive Officer of ROC said:

"Listing ROC shares on AIM is the next logical step in the Company's growth strategy. Although ROC’s trading record would qualify it to list on the Main Board of the London Stock Exchange, ROC chose to list on AIM because the recently introduced “fast track” concept makes it an administratively simple, cost efficient and relatively quick process.

ROC's conveyor belt of projects runs from new ventures and exploration to mature production, in areas which appear to be of interest to UK investors, particularly West Africa where ROC has established a meaningful presence and a successful track record during the last five years."

CLIFF HEAD JOINT VENTURE ANNOUNCES ITS INTENTION TO BRING FORWARD PART OF ITS DEVELOPMENT DRILLING PROGRAMME (01-09-2004)


CLIFF HEAD JOINT VENTURE ANNOUNCES ITS INTENTION TO BRING FORWARD PART OF ITS DEVELOPMENT DRILLING PROGRAMME



At a Joint Venture meeting held in Perth on 31 August 2004, the Cliff Head Joint Venture agreed, subject to rig availability, to bring forward some of the elements of the development drilling programme that had previously been planned for late 2005.

Specifically, the Joint Venture agreed to drill Cliff Head-5 at a location in the southeastern part of the field as a vertical “pathfinder” appraisal well that will assist in the planning of a horizontal development well that is scheduled to be drilled into that part of the field from the unmanned production platform. This well is designed to move reserve from the probable to the proven category but because it is a pilot well it will not be completed for production regardless of results. The second well, Cliff Head-6, will be drilled as a development well in the main horst and is expected to be suspended as a future oil producer and completed for production in late 2005. It is anticipated that both wells will be drilled during January 2005. The rescheduling of part of the Cliff Head development drilling programme is being considered because the WA-325-P Joint Venture is scheduled to bring a jack-up rig into the offshore Perth Basin in late 2004 thereby affording the Cliff Head Joint Venture a possible opportunity to accelerate part of its development drilling programme.

Bringing these wells forward will not impact on anticipated first oil production, which is still scheduled as a stretch target for end 2005. However, as a result of the rescheduled drilling, it is now expected that Final Investment Decision (“FID”) will formally be taken at end January 2005 as opposed to end December 2004.

Commenting on the rescheduled drilling, Dr John Doran ROC’s Chief Executive Officer stated that:

“It’s not often in this business that a Joint Venture can advise the market of its intention to bring some elements of its development drilling programme forward by the best part of a year, but, in this case, the Joint Venture is opportunistically responding to the possibility that a suitable rig may be available.”
