MOUNDSVILLE, W.Va. — The SW App Drilling team has set multiple industry benchmarks with the successful completion of the BW Edge MSH 210H, a well that team members lauded as a “postcard well” for its near-perfect execution. This engineering feat near Moundsville, West Virginia, includes the longest lateral ever drilled in the United States — extending over five miles — and has captured attention across the energy sector.

The BW Edge MSH 210H, operated on Rig EDC 41, achieved a historic suite of records:

— Longest lateral in U.S. land: 27,657 feet
— Longest well in U.S. land: 34,507 feet
— Longest single bit/BHA run in U.S. land: 30,368 feet
— 48-hour footage world record: 21,314 feet
— Expand Energy 24-hour footage record: 12,370 feet
— Expand Energy daily footage record: 2,774 feet/day

The achievement underscores the value of ultra-long laterals, especially in challenging terrains like Appalachia where surface access is constrained. By drilling from fewer surface locations to access premium reservoir targets, Expand Energy not only enhances hydrocarbon recovery but also reduces environmental impact and improves capital efficiency — critical in today's evolving energy landscape.
