After LNG, pipeline gas to Mexico is the second-largest U.S. export outlet — currently — bcf/d. The flows are almost entirely south-bound from Texas (Permian + Eagle Ford gas) into Mexico's power-gen sector, where they've been displacing fuel-oil burn over the last decade. Five major border crossings carry most of the volume; Sur de Texas-Tuxpan is the marine pipeline lateral that extends the network into central Mexico.

PIPELINE CROSSING · BCF/D ROUTE & ROLE Sur de Texas-Tuxpan — BROWNSVILLE TX → TUXPAN VER Subsea + onshore. Permian gas to central Mexico power. Roadrunner — PERMIAN BASIN → SAN ELIZARIO TX El Paso interconnect. Feeds Samalayuca + interior north. Trans-Pecos — WAHA HUB → PRESIDIO TX West Texas. Major outlet for Permian associated gas. Comanche Trail — WAHA HUB → SAN ELIZARIO TX Parallel Permian outlet. Helps clear basis blowouts at Waha. Σ MAJOR CROSSINGS = — bcf/d · remainder via Naco/Sasabe AZ + Otay Mesa CA + smaller TX laterals
