DENVER—Sterling Energy Investments LLC unveiled plans on May 8 to expand the processing capacity and associated natural gas gathering pipeline infrastructure of its Centennial System in the northeastern Denver-Julesberg (D-J) Basin to 220 million cubic feet per day (MMcf/d) to accommodate growing producer demand.

Sterling completed the first phase of the expansion of its existing Jackson Lake Processing Plant during second-quarter 2018 and plans to place in-service the fully funded cryogenic expansion of the Jackson Lake Processing Plant during fourth-quarter 2018.

In addition, Sterling announced that it will expand the capacity at its existing Centennial Gas Processing Plant by up to 120 MMcf/d. The permitting process for the Centennial Gas Processing Plant expansion project is underway with state and local authorities. Sterling anticipates commissioning of that expansion project during second-half of 2019.

Sterling’s Centennial System consists of over 450 miles of low-pressure gathering pipeline, spanning Weld, Morgan, and Logan counties in Colorado and Cheyenne County in Nebraska. It includes three interconnected natural gas processing plants to ensure reliable service, with each plant connected to a different downstream residue gas market to provide flow assurance for area producers. Residue gas takeaway is provided by Cheyenne Plains, Tallgrass Interstate Gas Transmission and Southern Star pipelines. NGL takeaway is provided by Overland Pass Pipeline.

“We are excited to offer D-J producers a full slate of midstream services: low-pressure gas gathering service, gas processing at multiple plants, condensate stabilization, a significant and reliable non-tributary water source and water distribution infrastructure, produced water gathering, produced water recycling and reuse and crude oil gathering,” said David Kenyon, president of Sterling. “Our continued investment in expansion projects across the Centennial System footprint ensures our producers receive timely access to the midstream infrastructure and markets necessary to maximize production and support their development plans.

“Sterling has been operating in the D-J Basin since 2000 and is excited to support the continued success of our producer partners.”
