MPLX LP has entered into a definitive agreement to acquire Northwind Delaware Holdings LLC (Northwind Midstream) for US$2.375 billion. Northwind Midstream provides sour gas gathering, treating, and processing services in Lea County, New Mexico. The portfolio includes over 200,000 acres (80,937 ha), 220 miles (354 km) of low pressure and high-pressure pipeline, five compressor stations, a treating and sequestration facility with 200 MMcf/d (5.6 x 106 m3/d) capacity, and two acid gas injection wells at 20 MMcf/d (566,337 m3/d) with a third permitted will that will bring its total to 37 MMcf/d (1.04 x 106 m3/d).
In May 2025, the company expanded its natural gas gathering and compression network throughout Lea County, placing into service its fifth compressor station with initial capacity of 25 MMcf/d (707,921 m3/d). This brings Northwind’s total compression capacity to about 225 MMcf/d (6.3 x 106 m3/d) across its full system. Northwind’s gathering and compression network, which is designed specifically to manage produced natural gas with high levels of hydrogen sulfide and carbon dioxide, includes 47,250 hp (35,248 kW) of compression.
MPLX’s expansion into sour gas gathering, treating, and processing in southeast New Mexico will enable additional solutions for its existing and new producer customers. The dedicated acreage and volumes associated with this system provide access to up to 400 MMcf/d (11.3 x 106 m3/d) of incremental gas available for processing and up to 70 thousand barrels per day of new natural gas liquids (NGL) volumes, accelerating growth opportunities for MPLX.
“The integration of these assets with our existing Delaware basin natural gas system will expand MPLX’s treating and blending operations,” said Maryann Mannen, MPLX president and chief executive officer. “The addition of 200,000 dedicated acres will increase MPLX’s access to natural gas and NGL volumes. The optionality to direct these new volumes through our integrated system will accelerate our growth opportunities in the Permian.”
Headquartered in Findlay, Ohio, MPLX is a diversified, large-cap master limited partnership that owns and operates midstream energy infrastructure and logistics assets including a network of crude oil and refined product pipelines; an inland marine business; light-product terminals; storage caverns; refinery tanks, docks, loading racks, and associated piping; and crude and light-product marine terminals. The company also owns crude oil and natural gas gathering systems and pipelines as well as natural gas and NGL processing and fractionation facilities in key US supply basins.
