ONEOK Tech Stack

Midstream energy infrastructure operator managing 60,000 miles of pipeline

Oil and Gas Tulsa, OK 5,001–10,000 employees Founded 1906 Public Company

ONEOK operates one of North America's largest midstream networks—gathering, processing, and transporting natural gas, NGLs, crude, and refined products across approximately 60,000 miles of pipeline. The tech stack is almost entirely industrial operations (Foxboro DCS, Rockwell PLCs, AVEVA, DeltaV, SCADA, Maximo) with minimal adoption velocity, reflecting a capital-intensive business where engineering and operations hiring (129 roles combined) far outpaces sales (2 roles), and active projects center on safety compliance, system expansion, and equipment reliability rather than digital transformation.
