Bonavista’s gross reserves are based on the GLJ reserve report dated January 31, 2018, GLJ reserve estimates based on forecast prices and costs as of January 1, 2018.
Boe 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 tip and does not represent a value equivalency at the wellhead.
Calculated based on the amount for the relevant reserve category divided by the 2018 production forecast for the applicable year prepared by GLJ.
Amounts may not add due to rounding.
