Enable Oklahoma Intrastate Transmission (formerly Enogex) keeps the pipelines gassed up. As part of Enable Midstream Partners, it provides integrated natural gas midstream services, including gas gathering, processing, transportation, and storage services, primarily in Arkansas and Oklahoma. It operates almost 2,300 miles of interstate pipeline, eight processing plants, and two underground storage facilities capable of holding 24 billion cu. ft. of gas. Enable Oklahoma is connected to third-party gas pipelines which, in turn, transport gas to markets across the US.
