Ron Harrell will address some of the most troubling and misunderstood aspects of the petroleum reserves reporting requirements imposed by the US Securities and Exchange Commission (SEC). Numerous ongoing compliance and enforcement issues stem from the SEC''s insistence on absolute conformance to reserves definitions issued more than a quarter century ago with little if any regard to the technological advances since 1978.  Ample time will be scheduled to permit open discussion about several technical matters as well as some commercial conditions required for the designation of proved reserves.
