Oneok is expanding gathering systems and its existing Sterling III pipeline to transport NGLs for EnLink Midstream and possibly other customers from the Stack play in Oklahoma to the Mont Belvieu hub in the Houston area. Tulsa-based Oneok will increase Sterling III’s capacity to 250,000 b/d from 190,000 b/d and connect its Arbuckle pipeline to EnLink’s Cajun-Sibon pipeline in southeast Texas.
