Notes
- The Reserve estimates shown in this report are based upon the joint reserve and resource definitions of the Society of Petroleum Engineers, the World Petroleum Congress, and the American Association of Petroleum Geologists.
- Proven and probable reserves in the UK represent the Group’s reserves as previously determined by ECL in April 2005, and subsequently reconfirmed in June 2006, in an independent valuation of some of the Group’s oil and gas assets in the Weald Basin. Further information is given in note 12 to the 2006 Report & Accounts.
- Quantities of oil equivalent are calculated using a gas-to-oil conversion factor of 5,800 scf of gas per boe.
