Volumes of production and injection are used to account for the CO2 volume stored at FWU.
The volume of CO2 that is purchased, flared, or recycled and reinjected are all known, so the volume stored can be calculated. To date, about 92% of the CO2 is in storage.
Cumulative (Top) and monthly (Bottom) volumes of CO2 use are shown below. All measurements are in metric tonnes.
