Executive Summary
Rockies natural gas cash prices have collapsed into the $1.00–$1.40/MMBtu range, raising the question of whether variable production costs now exceed market prices for a meaningful share of the region's roughly 10.2 Bcf/d of output. Our analysis, built on Hyperion's daily sub-regional production model and public operator cost disclosures, suggests the answer is nuanced: approximately 3.1 Bcf/d (30%) of Rockies gas is associated production from oil wells and is effectively insulated from gas-price economics. Of the remaining 7.2 Bcf/d of non-associated dry gas, we estimate 0.3–1.3 Bcf/d could face cash-cost curtailment depending on where within the $1.00–$1.40 band prices settle. The practical supply response, however, will more likely manifest as deferred drilling activity and accelerated natural decline rather than abrupt shut-ins.
The Production Landscape
The Rockies gas complex (excluding Permian-New Mexico, which prices at Waha) spans seven sub-regions, each with a distinct production profile. The chart below shows daily production trends since January 2025, illustrating both the scale and the relative stability of the region's output.
The DJ Basin/Niobrara (Colorado) dominates at 4.1 Bcf/d, followed by Wyoming at 2.6 Bcf/d and New Mexico (non-Permian) at 1.6 Bcf/d. These three sub-regions account for 82% of the total, and their differing gas-oil ratios determine how much of the region is truly exposed to gas-price stress.
The critical distinction is between associated gas—a byproduct of oil production that flows regardless of gas prices because the well's economics are driven by crude revenue—and non-associated dry gas, where the well's sole revenue stream is the gas molecule itself. In Colorado, 54% of output is associated gas from Wattenberg and DJ oil wells, making it the most insulated sub-region. Wyoming (17% associated) and the San Juan Basin (effectively 0%) sit at the opposite end of the spectrum.
Quantifying Shut-In Risk
For non-associated gas wells, the shut-in decision hinges on whether the cash price covers variable operating costs—primarily lease operating expense (LOE) and gathering, processing, and transportation (GP&T) fees. Full-cycle breakevens are irrelevant for existing wells; sunk capital costs do not factor into the keep-producing-or-shut-in calculus. Based on public operator disclosures (2024–2025 10-K filings and investor presentations), Rockies LOE + GP&T ranges from roughly $0.60/Mcf for efficient horizontal operators in the DJ Basin to $1.30+/Mcf for legacy vertical and conventional wells in Wyoming and the San Juan.
We model three price scenarios across the 7.2 Bcf/d of non-associated gas. At $1.00/MMBtu, we estimate roughly 1.3 Bcf/d is uneconomic—primarily the highest-cost conventional and marginal wells in Wyoming, San Juan, and legacy Colorado verticals. At $1.20/MMBtu, the at-risk volume drops to approximately 0.8 Bcf/d, and at $1.40/MMBtu, only about 0.3 Bcf/d of the least efficient production is cash-negative.
Wyoming and Colorado carry the largest absolute shut-in exposure, but for different reasons: Wyoming has a large non-associated base (2.2 Bcf/d) with a meaningful tail of higher-cost conventional wells, while Colorado's exposure is concentrated in its 1.9 Bcf/d of dry-gas horizontal production where variable costs are generally lower. San Juan and New Mexico together contribute roughly 0.4 Bcf/d of potential curtailment at $1.00, driven by aging conventional wells and coal-bed methane.
Why Actual Shut-Ins Will Likely Undershoot Estimates
Our scenario estimates represent a theoretical ceiling, not a forecast. Several structural factors will keep actual curtailments below these numbers. First, minimum volume commitments (MVCs) embedded in midstream gathering contracts mean producers often owe fixed fees whether they flow gas or not—making the effective cost of shutting in higher than simply comparing LOE to the spot price. Second, shut-in and restart costs are non-trivial: wellhead freeze protection, regulatory notifications, and the risk of formation damage (particularly in tight sands and CBM wells) create an asymmetric penalty that discourages temporary curtailments for what may be a seasonal price trough. Third, many producers are hedged at prices well above the current cash market, allowing them to absorb near-term losses on unhedged volumes while collecting above-market revenue on their hedge book.
The more consequential supply response will be deferred drilling. At $1.00–$1.40/MMBtu, no new dry-gas horizontal well in the Rockies achieves an acceptable full-cycle return, and rig counts in gas-directed basins will decline. With natural decline rates of 5–8% annually for the existing well stock, this translates into a steady production erosion of 0.4–0.6 Bcf/d per year—a more durable and predictable supply reduction than sporadic shut-ins.
Five Things to Watch Going Forward
1. Wyoming and San Juan daily production. These are the canaries in the coal mine. Both sub-regions are dominated by non-associated gas with higher-than-average variable costs. A sustained decline beyond normal seasonality—particularly a drop below 2.5 Bcf/d in Wyoming or 0.45 Bcf/d in San Juan—would signal active curtailments rather than natural decline.
2. Rockies gas-directed rig counts. Rig activity is the leading indicator of future production. If gas-directed rigs in the Rockies fall below 15 (from current levels near 22), it would confirm that operators are pulling back investment, locking in a production decline trajectory 6–9 months out.
3. Basis differentials at CIG and Cheyenne Hub. Rockies basis has historically recovered by April–May as heating demand fades and pipeline maintenance season begins. If the CIG basis remains wider than -$0.80 to Henry Hub into late March, it would suggest structural oversupply rather than seasonal weakness, raising the probability of actual shut-ins.
4. WTI crude prices. The 3.1 Bcf/d of associated gas is only "protected" so long as oil production remains economic. A crude price decline below $55/bbl would begin to stress Rockies oil wells, potentially unlocking associated gas curtailments that our base case assumes away. Conversely, oil prices above $75/bbl could accelerate DJ Basin oil drilling and push associated gas volumes higher, further depressing regional gas prices.
5. Pipeline maintenance schedules. Rockies takeaway constraints (particularly on Cheyenne Plains, Colorado Interstate, and Rockies Express) can exacerbate basis blowouts during maintenance season. Monitor Hyperion pipeline flow data and operator critical notices for planned outages that could temporarily strand production and force involuntary curtailments.
Conclusion
At $1.00–$1.40/MMBtu, Rockies natural gas prices are testing the variable cost floor for a meaningful but ultimately limited share of the region's production. The associated gas buffer—roughly 30% of total output—provides a structural floor beneath which production cannot fall absent an oil price collapse. Our scenario analysis suggests 0.3–1.3 Bcf/d of non-associated gas faces cash-cost curtailment risk, though practical considerations (MVCs, restart costs, hedges) will keep realized shut-ins at the lower end of that range. The more important story is the drilling response: at current prices, new dry-gas development in the Rockies is uneconomic, and the resulting investment drought will steadily erode production at 5–8% annually. For traders and analysts, the signal to watch is not sudden shut-in announcements but rather the slow grind lower in rig counts and the eventual production base decline that follows.
