Executive Summary
The Montney Formation is Canada's most important unconventional play, projected to provide 58-63% of all Canadian natural gas production through 2050 according to the Canada Energy Regulator. Currently producing approximately 2 million barrels of oil equivalent per day, the Montney has attracted major U.S. operators including Ovintiv, Murphy Oil, and ConocoPhillips.
Key highlights:
- Resource Estimates: Ranges from 22 years (Kimmeridge) to 45 years (Enverus) of inventory
- Current Production: ~2 million BOE/d
- LNG Catalyst: LNG Canada export facility could transform economics
- Decline Concerns: Well productivity declining in some core areas
However, recent analysis suggests that low-cost, readily recoverable gas may be more limited than industry estimates imply.

Historical Background
Early History and Discovery
The Montney Formation has been known to geologists for decades but was considered uneconomic until the application of horizontal drilling and hydraulic fracturing techniques in the late 2000s.
Montney Formation Timeline
| Pre-2008 | Formation known but considered uneconomic for commercial development |
| 2008-2010 | First horizontal wells demonstrate commercial viability |
| 2011-2020 | Rapid development, production growth accelerates |
| 2018 | LNG Canada FID announced - major demand catalyst |
| 2023 | 16,848 wells drilled through year-end |
| 2024-2025 | LNG Canada Phase 1 startup expected, drilling activity reduced awaiting higher prices |
U.S. Operator Interest
The Montney has attracted significant attention from U.S. operators seeking shale exposure outside the increasingly consolidated Permian Basin:
- Ovintiv: Major Montney position, headquartered in Denver
- Murphy Oil: Active Montney development
- ConocoPhillips: Expanded Canadian presence
- Private Equity: Multiple firms evaluating entry opportunities
Geological Characteristics
Reservoir Properties
The Montney Formation is a Lower Triassic tight siltstone and fine-grained sandstone that requires horizontal drilling and hydraulic fracturing for commercial production.
Montney Reservoir Properties
Decline Characteristics
A June 2024 David Suzuki Foundation report analyzed 16,848 wells drilled through 2023:
- Typical Peak: ~0.8 MMcf/d in month 2 or 3
- 60-Month Production: Declines to ~0.2 MMcf/d (75% decline)
- Productivity Concerns: Well productivity declining in some of the best parts of the play
Inventory Reality Check
"Although the Montney is clearly very large, its ultimate potential could easily be overestimated as it was based on the limited data available in 2013 and, as recent drilling and production data indicate, well productivity is declining in some of the best parts of the play, suggesting that supplies of low-cost, readily recoverable gas may be more limited than previously thought."

Estimated Well Costs (2024 CAD)
2024 Drilling Activity
Operators have reduced Montney drilling activity in 2024:
- Permit Activity: Licensing exceeding 2024 rate, but fewer wells spudded
- Operator Behavior: "Holding off on drilling, likely waiting for commodity prices to rebound rather than burn through inventory at low prices"
- LNG Catalyst: LNG Canada startup could reignite drilling activity
Production Decline Characteristics
Steep Initial Decline
- Year 1 Decline: ~65-70% from initial production
- Year 5 Production: ~25% of initial rate
- Conventional gas wells typically decline 5-8% annually
Production Decline Analysis
The Shale Decline Reality
While industry headlines tout record production, the underlying data reveals a critical truth: shale wells experience dramatic production declines that require constant drilling just to maintain output. This creates a "treadmill" effect where massive capital expenditure is needed simply to prevent production collapse.
Industry Expert Analysis
"New wells drilled in 2023 may ultimately produce roughly half of what new wells from 2019 will ultimately produce. The industry is sacrificing future production to maximize short-term output."
— Art Berman, Petroleum Geologist (40+ years experience)The Lateral Length Paradox
Since 2014, the industry has nearly tripled average lateral lengths from 5,000 ft to 14,000+ ft. While this increases initial production rates, it also accelerates decline—effectively using "wider straws" to drain reservoirs faster.
Key Investment Considerations
Decline Risks
- Hyperbolic Decline: 65-75% production loss in year 1 (vs 5-6% for conventional)
- Child Well Problem: 85% of new wells produce less than expected
- Inventory Exhaustion: Tier 1 acreage running out within 3-5 years
- Treadmill Economics: Continuous drilling required just to maintain output
Counter-Perspectives
- Technology continues improving operational efficiency
- Infill drilling potential may extend productive life
- Multi-zone development can maximize recovery
- Higher commodity prices improve economics on marginal wells

Remaining Potential & Future Opportunities
Development Potential
Inventory life estimates vary dramatically depending on the source:
- Enverus: 45 years of drilling remaining at current pace
- Kimmeridge: 22 years based on "front-end inventory duration"
- Reality: Core area productivity declining, true Tier 1 inventory uncertain
Potential Catalysts
- LNG Canada: Major new demand source for Montney gas
- Low Breakeven: Among lowest-cost gas plays in North America
- Liquids-Rich: Condensate improves wellhead economics
- Slower Exploitation: Less mature than U.S. shale plays
Key Risks
- Productivity Decline: Core areas showing reduced well performance
- Overestimated Resource: Based on 2013 data that may be optimistic
- Steep Well Decline: 65-70% first-year production drop
- Regulatory Risk: BC/Alberta environmental policies
LNG Export Opportunity
LNG Canada could transform Montney economics by providing:
- Premium Pricing: Access to Asian LNG markets
- Demand Security: Long-term offtake agreements
- Investment Catalyst: Justifies additional drilling activity
Conclusion
The Montney Formation represents Canada's most significant unconventional resource, but investors should carefully examine the gap between industry inventory estimates and on-the-ground well performance data.
Kingdom Exploration Assessment
Strengths
- 58-63% of future Canadian gas production
- ~2 million BOE/d current production
- LNG Canada export catalyst
- Liquids-rich improving economics
- Lower breakeven than many U.S. plays
Challenges
- 65-70% year-1 decline rates
- Core area productivity declining
- Inventory estimates may be overstated
- Operators reducing activity at current prices
- Carbon policy/environmental regulatory risk
The Montney's value proposition depends heavily on LNG export development and the assumption that well productivity trends can be maintained or improved. Investors should scrutinize operator claims about inventory depth and examine actual well performance data from recent vintages.
