Northwind Midstream Partners has expanded its off-spec gas treating capacity, carbon sequestration and related infrastructure in Lea County, New Mexico, US.

This development included the construction and commissioning of 150 million cubic feet per day (mcf/d) of high-circulation amine treating capacity, two acid-gas disposal wells, more than 200 miles of large-diameter pipelines and 41,750hp of compression across five compressor stations.

The system expansion is supported by long-term agreements and more than 165,000 acres from leading oil and gas producers in the Northern Delaware Basin.

Northwind is also constructing a natural gas infrastructure system that adheres to National Association of Corrosion Engineers (NACE) standards and is designed to handle produced natural gas with high levels of carbon dioxide and hydrogen sulphide.

The phase one buildout, expected to be completed by mid-2025, is centred around the Titan Treating Complex.

At this complex, Northwind recently increased its amine treating capacity by 100mcf/d and added a deep acid-gas injection and carbon sequestration well.

The Titan Complex now has a total treating capacity of 150mcf/d and operates two acid-gas injection wells.

The completion of phase one will see the total capacity rise to 200mcf/d, with plans already in place to further expand this capacity to 400mcf/d by 2026, backed by a final investment decision and customer support.

Alongside the Titan Complex expansion, Northwind has also recently enhanced its low and high-pressure natural gas gathering and compression network throughout Lea County.

Northwind CEO Matt Spicer said: “Increased off-spec gas gathering, treating and sequestration capacity is vital to the oil and gas industry’s continued success in Lea County. The expanded Titan facility and associated pipelines and compression commissioned by Northwind provide our upstream producer partners a safe and economical solution for off-spec gas.

“Our facilities and infrastructure enable producers to effectively develop the prolific benches in the Northern Delaware Basin while also meaningfully reducing emissions.”
