Alberta's Basel Belly River Shale Draws New Oil Drilling Wave
Oil drillers are returning to a gas formation once left for dead in Alberta, World Oil reports in a Bloomberg-sourced story on Obsidian Energy Ltd. and Yangarra Resources Corp.’s push into the Basal Belly River shale.
Market Impact
The Alberta Energy Regulator granted 15 drilling licenses targeting or ending at the Basal Belly River formation in the first half of 2026, the most for that period in 14 years, according to World Oil. The formation sits southwest of Edmonton in an area called Willesden Green and was historically a natural gas play, with more than 1,000 wells drilled there in 2005, 95% of them for gas.
The revival gained momentum in June when Obsidian agreed to buy 35 sections of land in the field from Highwood Asset Management Ltd. for C$105 million (about $75 million) in cash, a deal that included roughly 2,500 bopd of production, about 75% of it light oil. Obsidian CEO Steve Loukas told Bloomberg that early wells drilled in the formation “had good success,” with an initial well from fall 2024 producing “constructive results” that carried through 2025 and 2026. Obsidian plans a six-well development program next year to push acquired-asset production to 3,000 bpd, with each well costing about C$5 million to develop. Combined with existing output, the company’s Basel Belly River production could reach 7,000 bpd, according to World Oil, out of an estimated 10,000 to 13,000 bpd total from the area.
The shift mirrors a broader Western Canada trend toward liquid-rich drilling in formations like Montney and Duvernay after years of weak gas prices. Western Canadian gas has traded about $1.70 per MMBtu below U.S. gas over the past five years, a discount persisting since British Columbia LNG exports began last year, while local oil prices have been supported by Middle East conflict and new export capacity from the expanded Trans Mountain pipeline.
What It Means for Subcontractors
- Drilling and completions crews in the Willesden Green area southwest of Edmonton should expect near-term work: Obsidian’s six-well 2026 development program alone represents roughly C$30 million in drilling spend at C$5 million per well.
- Fracing and pressure-pumping contractors should watch for follow-on activity from Yangarra Resources, which is also fracing the Basel Belly River sandstone, alongside Obsidian’s expanding footprint.
- Companies with hydraulic fracturing experience in sandstone reservoirs are positioned to bid as operators convert legacy gas wellbores and permits toward oil-focused completions in the formation.
- Field service firms tied to Montney and Duvernay liquids plays should note the same economics, a persistent $1.70/MMBtu Canadian gas discount and Trans Mountain export capacity, are now pulling operator budgets toward Basel Belly River, suggesting similar reallocation could hit other Alberta gas-legacy formations.
- Land and midstream-adjacent contractors should track further AER licensing data, since 15 licenses were issued in just the first half of 2026 and the pace could signal additional acreage deals beyond the Highwood Asset Management transaction.
