EXHIBIT 1 --------- SUPPLEMENTARY OIL & GAS INFORMATION (UNAUDITED) This supplementary crude oil and natural gas information is provided in accordance with the United States FAS 69, "Disclosures about Oil and Gas Producing Activities", and where applicable is reconciled to the US GAAP financial information. NET PROVED CRUDE OIL AND NATURAL GAS RESERVES The Company retains qualified independent reserves evaluators to evaluate the Company's proved crude oil and natural gas reserves. o For the years ended December 31, 2006, 2005, and 2004 the reports by Sproule Associates Limited ("Sproule") and Ryder Scott Company covered 100% of the Company's conventional reserves; o For the year ended December 31, 2003, the reports by Sproule covered 100% of the Company's conventional reserves. Proved crude oil and natural gas reserves are the estimated quantities of crude oil, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are reserves that can be expected to be recovered from existing wells with existing equipment and operating methods. Estimates of crude oil and natural gas reserves are subject to uncertainty and will change as additional information regarding producing fields and technology becomes available and as future economic and operating conditions change. The following table summarizes the Company's proved and proved developed conventional crude oil and natural gas reserves, net of royalties, as at December 31, 2006, 2005, 2004 and 2003: North North Offshore Crude oil and NGLs (mmbbl) America Sea West Africa Total -

A discount factor of 10% has been applied in determining the standardized measure of discounted future net cash flows. The Company does not believe that the standardized measure of discounted future net cash flows will be representative of actual future net cash flows and should not be considered to represent the fair value of the crude oil and natural gas properties. Actual net cash flows will differ from the presented estimated future net cash flows due to several factors including: o Future production will include production not only from proved properties, but may also include production from probable and potential reserves; o Future production of crude oil and natural gas from proved properties will differ from reserves estimated; o Future production rates will vary from those estimated; o Future rather than year-end sales prices and costs will apply; o Economic factors such as interest rates, income tax rates, regulatory and fiscal environments and operating conditions will change; o Future estimated income taxes do not take into account the effects of future exploration expenditures; and o Future development and asset retirement obligations will differ from those estimated. Future net revenues, development, production and restoration costs have been based upon the estimates referred to above.
