22. RMI, Issues Across the ProcessShell Reserves Audit: Typical business practice improvements… • Inadequacy of Shell Reserve Guidelines • Slow to Incorporate SEC updates • Did not encourage review of existing bookings • Reserves definitions differ for Internal / Operations & those for regulatory compliance Strategy • Requires systematic & consistent use of external 3rd party experts in reserve audits • No consistent application of standards across BU’s • Need for Roles and responsibilities to be more clearly defined e.g. in de-booking of reserves. Process • Weakness in various structures: • Lack of Reserve Audit independent from business (now reports into Technology head) • Need for Finance / Legal reporting structures to be independent from business functions, and reporting direct to group heads. • Lack of appropriate resources for both Group Reserve Management (internal) and Reserve Audit (Compliance) • Revised reserve component of Incentive plans Organization Technology • Lack of Systematic document retention policy and audit trail • Need for document Integrity / Security / Audit checks

23. Recent Industry Events – Reserves Management Top of mind issues for CEOs, shareholders and regulators… • Announced cuts in the estimated oil and gas reserves at Royal Dutch/Shell, El Paso and other E&P companies have raised questions. • How could companies suddenly have far less potential oil and gas than initially reported? The answer is in a mixture of imprecise regulations, geological guesswork and corporate culture that go into the accounting of such reserves. NYTimes 031204
