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.
