Bear Creek Gas Plant Carbon Capture

Capture from ONEOK's natural gas processing facility to be sequestered in the Roughrider Carbon Storage Hub. ONEOK’s Roughrider project is a proposed large-scale carbon storage hub in western North Dakota being developed under the U.S. Department of Energy CarbonSAFE Phase II program. The project is designed to aggregate CO₂ from multiple regional industrial sources, including natural gas processing facilities, power generation, ethanol plants, and upstream oil and gas operations, and permanently store the CO₂ in deep stacked saline formations within the Williston Basin. The hub is expected to support long-term storage of more than 50 million tonnes of CO₂ over a 30-year period and is structured around centralized storage infrastructure with shared transportation and injection capacity. The project scope includes drilling a full-depth stratigraphic test well, collecting more than 1,000 feet of core, conducting drill stem tests and geophysical logging, and completing reservoir modeling and injection simulations to characterize up to four prospective storage complexes. ONEOK is leading feasibility analysis, site development planning, and technical and economic assessments to position the Roughrider hub for future Class VI permitting.
