The 2017 data have been recalculated to exclude ASESA as the data for this asset are not included this year.

2 For the Chemical business, the main tonnage of process raw materials is included, not reporting the volume of chemicals. 3 At the business of Exploration & Production and in the Petrocan, Aviation, SIS and CMD plants there is no consumption of raw materials.
