MPLX reported its 3Q 2025 earning on Tuesday Nov 4th. President and CEO, Maryann Mannen, highlighted two strategic acquisitions completed in Q3: securing full ownership of the BANGL pipeline and the acquisition of the Titan sour gas treating complex in the Delaware basin.
Natural Gas Projects
MPLX continues to advance its two-basin gas strategy: Permian for growth and Marcellus/Utica for scale. The 300 MMcf/d Harmon Creek III plant in Washington County, PA is expected online by year-end 2026, bringing total Appalachia processing capacity to >10 Bcf/d. In the Permian, the Titan sour-gas treating complex is adding ~250 MMcf/d, increasing sour gas treating capacity to >400 MMcf/d by 2H 2026.
On the residue gas side, MPLX maintains takeaway access to the Gulf Coast through interests in the Matterhorn and Whistler pipelines (in service) and the Blackcomb and Eiger projects (under development), supporting flows from its ~1.4 Bcf/d Permian gas processing footprint. MPLX also has equity interest in the Traverse and Rio Bravo pipeline projects being developed along the Texas Gulf coast connecting between the Katy and Agua Dulce hubs with access to NextDecade’s under construction Rio Grande LNG export terminal in Brownsville, TX.
NGL / LPG Exports
MPLX closed on the remaining 55% of the BANGL pipeline in July for ~$700MM, consolidating ownership and operational control. BANGL is being expanded by ~50 Mb/d to ~300 Mb/d by 2H 2026, improving direct Y-grade routing from the Permian to fractionation and export markets on the Gulf Coast.
At the downstream end of the system, MPLX continues the planned development of the Texas City fractionation complex and LPG export JV. RBN did a deep dive on the project in our blog, "At Last - New NGL Pipes, Fracs and LPG Export Terminal Give MPLX, ONEOK What They've Wanted"
