MPLX's latest earnings call, on August 4th, reinforced that the partnership remains focused on expanding its natural gas and NGL value chain rather than pursuing major crude oil infrastructure projects. Management highlighted continued strong producer activity across the Marcellus, Utica and Permian basins, driving high utilization rates at its gathering systems, processing plants and takeaway pipelines.
Project execution remains the central theme for 2026. During the quarter, MPLX placed the 200 MMcf/d Secretariat I processing plant (red diamond in Fig. 1) in the Delaware basin into service and recently started up Harmon Creek III, 300 MMcf/d, in the Utica/Marcellus. The partnership also confirmed that additional sour gas processing capacity, gas gathering expansions and NGL projects are scheduled to enter service over the balance of the year. These include an expansion of the Permian NGL pipeline, BANGL(blue line) to 300 Mb/d, incremental sour gas treating in the Delaware basin at the Titan processing complex (blue diamond). Along with the Q4 startup of the WhiteWater Midstream operated 2.5 Bcf/d Blackcomb pipeline (white/black dashed line). MPLX owns a 34% stake in Blackcomb.
