Advances in drilling and completion design, longer laterals, and stronger well results are pushing the Mancos Shale back into focus in the San Juan Basin. Operators such as Mach Natural Resources and LOGOS Energy are showing that modern Mancos wells can compete with some of the strongest U.S. gas plays on a productivity basis, while recent activity near the New Mexico-Colorado border is reshaping how the basin is being viewed.
That shift is visible not just in well results, but in where activity is clustering. Recent drilling has concentrated in the dry-gas Mancos core, where active wells are lining up with existing compressor and processing infrastructure. The basin’s rig count rose from a low of two in late 2024 to a peak of eight last summer, with most of that activity directed toward the Mancos gas play.
The story is also about execution. LOGOS reported standout well results including Rosa Unit #756H and Pad 26, while Mach’s underwriting case points to large reserve recovery from relatively shallow horizontal Mancos wells. Mach’s 2025 acquisition of IKAV’s San Juan assets, including acreage and midstream infrastructure, reinforced that this is no longer a fringe basin story.
Why it matters
-
Modern Mancos wells are starting to compete with top-tier U.S. gas plays on productivity.
-
Rig activity has moved sharply higher as operators concentrate on the dry-gas Mancos core.
- The San Juan story is no longer just about acreage, it is about execution, well design, and infrastructure-backed development.
-
Existing compressor and processing assets help explain why renewed drilling is clustering where it is.
