1 The Company records production in metric tonnes. Barrelization ratios are used for illustrative purposes only and are calculated based on the Company's estimate of the typical API of oil produced from specific fields. Starting from September 2016, the barrelization ratios used are 7.58 bbl / tonne for Exillon WS and 7.43 bbl / tonne for Exillon TP, as compared to previously used ratios of 7.8037 bbl / tonne for Exillon WS and 7.44 bbl / tonne for Exillon TP. The ratios' adjustment relates to the change in estimates of the typical API based on the latest report on proved and probable reserves of the Group prepared by Miller and Lents Ltd, independent engineering consultants.
