A Boe is a barrel of oil equivalent on the basis of 1 Boe to 6 Mcf of natural gas. Boe’s may be misleading, particularly if used in isolation. A Boe conversion ratio of 1 Boe for 6 Mcf is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
