Reference to BOE means barrels of oil equivalent and is derived by converting gas to oil at the ratio of six thousand cubic feet (mcf) of gas to one barrel (bbl) of oil. BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner top and does not represent a value equivalency at the wellhead. References to BOEPD means barrels of oil equivalent per day.
