The gas produced at the Big Sky Carbon Hub is roughly 0.5% helium and 87.5% CO₂. From that single stream, helium is purified and sold, the CO₂ is captured and managed under Section 45Q, and a portion of the CO₂ is used to recover oil at the wholly owned Cut Bank field.
Because every stream shares the same wells and the same infrastructure, each revenue line is added at a fraction of the cost of a standalone business.
