The Barnett-Woodford formation has emerged as a significant source of oil, containing 3 billion barrels of undeveloped recoverable reserves and over 6,400 drilling locations. This development marks a shift for Texas operators, as recent data shows well performance in the formation exceeding the Midland basin base by 30%.
Why it matters
The formation has transitioned into a material source of incremental inventory, offering operators new, high-performance drilling opportunities that were absent from development models as recently as April 2025. This allows for a recalibration of long-term production strategies based on improved efficiency metrics.
The play holds 3 billion barrels of undeveloped recoverable oil across 6,400 potential locations, with breakevens ranging from $41 per barrel to $46 per barrel. Analysts identified these figures by adjusting for development maturity and well density across the Midland basin.

The details
Development has accelerated as operator programs capitalized on drilling results that consistently outperformed the basin average. Performance is not uniform, with Ector, Crane, and northwestern Upton counties hosting the highest-performing assets at a $42 per barrel breakeven. Meanwhile, wells in southeastern Andrews, southwestern Martin, and western Midland counties show higher costs, with breakevens averaging $46 per barrel.
Timeline
2025: Barnett-Woodford well performance began exceeding the basin base.
April 2025: The interval was absent from development models.
October 7, 2026: Enverus Intelligence Research released the analysis.
Market Landscape
The Barnett-Woodford formation now represents a resource size equivalent to 75% of the Bakken and Three Forks plays. This addition marks a shift in how Texas producers view reserve growth compared to established industry standards.
Operators should review their Midland basin acreage to determine if current holdings overlap with these high-performing zones in Ector, Crane, and Upton counties. Evaluating these breakeven points against your current cost structure is essential for future capital allocation.
The takeaway
The Barnett-Woodford is no longer an overlooked interval but a core inventory play that mandates a review of existing lease positions. Operators should monitor well-performance data in the identified high-performing counties to benchmark against their internal drilling cost per foot.
