Natural Gas - In its Natural Gas Gathering and Processing segment, the company completed an expansion of the injection capabilities of its Oklahoma natural gas storage facilities, which allowed it to utilize and subscribe an additional 4 Bcf of existing storage capacity, which is fully subscribed through 2027 and 90% subscribed through 2029. In addition, the company completed the electrification of certain compression assets on Viking to maintain reliability of its operations while lowering its Scope 1 emissions from this equipment. Viking is seeking to recover its investment in the project through a proposed increase in rates filed in July 2023. In February 2024, the FERC approved its Saguaro Connector Pipeline, L.L.C.'s Presidential Permit application to construct and operate new international border-crossing facilities at the U.S. and Mexico border. The proposed border facilities would connect upstream with a potential intrastate pipeline, the Saguaro Connector pipeline. Additionally, the proposed border facilities would connect at the international boundary with a new pipeline under development in Mexico for delivery to a liquefied natural gas export facility on the west coast of Mexico. The final investment decision on the Saguaro Connector pipeline is expected by mid-year 2024. NGLs - In its Natural Gas Liquids segment, the company benefited from increased volumes in 2023, due primarily to increased production in the Permian Basin and Rocky Mountain region. In addition to construction of its MB-6 fractionator, activities are underway to complete the looping of the West Texas NGL pipeline, which will more than double the company's NGL capacity out of the Permian Basin. The full loop is expected to be in service in the first quarter of 2025. The company also has begun initial work, primarily on long-lead-time components, towards expanding the Elk Creek pipeline to 435 MBbl/d to provide capacity for growing volumes in the Rocky Mountain region, which will bring its total pipeline capacity out of the Rocky Mountain region to 575 MBbl/d. The Elk Creek pipeline expansion is expected to be in service in the first quarter of 2025. Refined Products and Crude - The company's 2023 results include the period from September 25, 2023, to December 31, 2023. Strategy The company commits to developing processes to drive a zero-incident culture for the well-being of its employees, contractors and communities. Safety and environmental responsibility continue to be primary areas of focus for it, and its emphasis on safety has produced improving trends in the key indicators it tracks. The company strives to be an employer of choice and continue to focus on attracting, selecting and retaining talent, advancing an inclusive, diverse and engaged culture and developing individuals and leaders. Segments The company operates through four segments: Natural Gas Gathering and Processing; Natural Gas Liquids; Natural Gas Pipelines; and Refined Products and Crude. Natural Gas Gathering and Processing segment In its Natural Gas Gathering and Processing segment, raw natural gas is typically gathered at the wellhead, compressed and transported through pipelines to the company's processing facilities. Most raw natural gas produced at the wellhead also contains a mixture of NGL components, including ethane, propane, iso-butane, normal butane and natural gasoline. Gathered wellhead natural gas is directed to the company's processing plants to remove NGLs resulting in residue natural gas (primarily methane). Residue natural gas is then recompressed and delivered to natural gas pipelines, storage facilities and end users. The NGLs separated from the raw natural gas are delivered through NGL pipelines to fractionation facilities for further processing. Some of the heavier NGLs may separate upstream of processing and fractionation and are sold as condensate at NGL or crude oil markets. The company's Natural Gas Gathering and Processing segment provides these midstream services to producers in North Dakota, Montana, Wyoming, Kansas and Oklahoma. Rocky Mountain Region - The Williston Basin is located in portions of North Dakota and Montana and includes the oil-producing, NGL-rich Bakken Shale and Three Forks formations. The company has more than 3 million dedicated acres in the Williston Basin. The Powder River Basin is primarily located in Wyoming, which includes the NGL-rich Niobrara, Frontier, Turner and Mowry formations where the company provides gathering and processing services to customers in the eastern portion of the state. Mid-Continent region - The Mid-Continent region includes the gas and oil-producing Anadarko Basin, which includes the NGL-rich SCOOP and STACK areas, including the Cana-Woodford Shale, Woodford Shale, Springer Shale, Meramec, Granite Wash and Mississippian Lime formations of Oklahoma and the Hugoton Basin in Kansas.
