• Lessons Learned from the Large-Scale CO2 Stimulation of 11 Unconventional Wells in the Williston Basin: A Practical Review of Operations, Logistics, Production Uplift, and CO2 Storage

    The paper introduces the results of the first CO2 fracturing campaign conducted in the Williston Basin. From 2015 to 2019, 11 horizontal multi-stage wells were safely stimulated using a CO2-hybrid design to improve production and store CO2 underground. The paper presentation provides a range of potential production uplift for both 12-month production and EUR. It also provides the range of CO2 concentrations produced back to the surface and an estimate of CO2 storage potential based on extensive compositional monitoring. 

    The analysis provides new insight to the storage potential for CO2 fracturing, EOR, and/or carbon capture and storage applications in the Williston Basin and other ultra-tight formations. 

    This presentation is from the 2022 SPE Hydraulic Fracturing Technology Conference and Exhibition.
