New Closed Blender Reduces Footprint, Gasification of CO2 in Waterless Fracturing

Carbon dioxide (CO₂) waterless fracturing uses liquid CO₂ to replace water as the fracturing fluid in reservoir stimulation. The continuity and reliability of the blender are key factors determining performance of the operation. The complete paper proposes a novel closed blender that uses a vertical, rather than horizontal, tanker. This modification can reduce the footprint and effectively suppress CO₂ gasification.
