MPLX Maintains Regional Gas Transmission Footprint Across New Mexico and Oklahoma
The company's midstream operations focused on interstate transmission services through its MarkWest subsidiaries during the 2024 reporting cycle.
MPLX (MPLX) operated its natural gas transmission assets through a network of specialized subsidiaries during 2024, maintaining critical infrastructure links in the Southwest and Southern Plains. The company managed these interstate services primarily through MarkWest New Mexico, L.L.C. (NM) and MarkWest Pioneer, L.L.C. (OK).
MarkWest New Mexico provided natural gas transmission services within New Mexico. The entity operated as a Texas-based limited liability company, serving as a primary conduit for regional gas movement.
Simultaneously, MPLX utilized MarkWest Pioneer to manage its transmission obligations in Oklahoma. These two operating units formed the core of the company's regulated gas transmission posture for the report year, ensuring the flow of natural gas across state lines to meet regional demand.
