Roc Oil Company Limited 29 April 2005 ROC OIL COMPANY LIMITED (ABN 32 075 965 856) REPORT TO SHAREHOLDERS Activities for the Quarter Ended 31 March 2005 SUMMARY Key corporate events occurred during the Quarter which radically improved the Company's already strong balance sheet and set the stage for consistent production growth during the next several years. To a large measure these changes were achieved by the very profitable sale of the Saltfleetby Gas Field and the Final Investment Decision taken with regard to the Cliff Head Oil Field. Therefore, quarter-on-quarter comparisons of the Company's production and sales revenue should only be undertaken with reference to consequential changes in the Company's cash and receivables position over the same period. Because of ROC's strategy of monetising mature reserves and production, the former has been greatly reduced while the latter has been greatly increased; to the point where it provides a very solid financial framework for ROC's future. -------------------------------------------------------------------------------- HIGHLIGHTS Cash and receivables increased to ROC's cash and receivables increased to a a record $205 million. record $205 million as at January 2005, primarily as a result of the £44 million/ $109 million sale of the Saltfleetby Gas Field, which generated an after tax profit estimated on the basis of AGAAP to be in the order of $70 million. Debt remained at zero. The corresponding reduction in Production during the Quarter reduced from production is viewed as temporary. 2,808 BOEPD to 29 BOEPD reflecting the impact of the sale of the Saltfleetby Gas Field. This reduction is considered by the Company to be a temporary situation which will be rectified within 12 months when ROC expects to be producing between 5,000 BOPD and 10,000 BOPD from fields currently under development. Final Investment Decision made A two well appraisal/development drilling with regard to Cliff Head Oil programme at Cliff Head provided mixed Field Development following results. Cliff Head 5 was a dry hole that completion of FEED and mixed came in 56 m low to prognosis while the appraisal/development drilling high angle Cliff Head 6 Development well results drilled 93 m of gross oil pay with a 70% net to gross. The well was suspended for future oil production. Subsequent to the two wells and the completion of Front End Engineering and Design ('FEED'), a Final Investment Decision ('FID') regarding the Cliff Head Oil Field was taken in March 2005. The anticipated cost of developing the 14 MMBO field is $227 million. Development continued at the Development activities continued at the Chinguetti Oil Field. Chinguetti Oil Field, offshore Mauritania, with a continuing oil production and water injection drilling programme occurring in parallel with work on production and sub-sea facilities. The latest round of appraisal Tiof-6 encountered about 124 m of gross drilling concluded at the Tiof Oil oil pay with a net pay thickness Field, with a maximum flow rate of comfortably within the 10-40% range 12,400 BOPD from Tiof-6. established by other wells in the area. This areally extensive field is yet to be fully defined, but its potential for commercial development was enhanced when Tiof-6 flowed oil at rates up to 12,400 BOPD. In the offshore Perth Basin, a dry Prior to being plugged and abandoned, the exploration well was drilled Hadda-1 exploration well encountered 20 m of tight sands with oil shows in the offshore Perth Basin. Tight gas sands encountered, The Errington-1 exploration well in onshore UK. northern England encountered approximately 100 net metres of gas shows in low porosity sands. The results will be reviewed in more detail in order to determine whether or not the well would be amenable to a fraccing programme. Pre-development work continued on Both the Blane Oil Field and Enoch Oil and two fields in the North Sea. Gas Field continue to be subject to pre-development studies designed to allow the relevant joint ventures to consider, and if appropriate, approve, the respective field developments during mid-2005.
