Obsidian Bets on Alberta's Forgotten Gas Fields as an Oil Play
A C$105 million land deal in the Belly River formation signals Alberta operators are targeting oil in reservoirs once drilled almost exclusively for gas.
A formation that produced mostly natural gas for decades on the edge of the Canadian Rockies is now attracting oil drilling. Rigzone reported Saturday (2026-07-18) that Obsidian Energy and Yangarra Resources are fracking the Belly River sands for oil, following Obsidian's agreement in early June 2026 to pay C$105 million (about $75 million) to Highwood Asset Management for 35 sections of land in the play, a deal that added roughly 2,500 barrels of oil equivalent per day, or about 9% of Obsidian's total output.5
About 75% of that new production is light oil. ICE Brent crude front-month closed at $88.26 per barrel on Friday (2026-07-17), while NYMEX Henry Hub front-month gas settled at $2.91 per MMBtu. The pricing gap between the two has been wide enough to shift development decisions in formations where operators have a choice, and Obsidian's existing Belly River production is already oil-weighted, making the Highwood acreage a natural extension of an established position.5
The geological record was set in 2005. More than 1,000 wells were drilled in the Belly River that year, with 95% of them extracting natural gas, according to Alberta Energy Regulator data. When North American gas prices fell, operators moved on. Now companies are returning to the same sands, drilling for the oil intervals their predecessors bypassed.5
"You started to see some initial wells drilled in the Belly River that had good success," Steve Loukas, Obsidian's chief executive, said in comments reported by Rigzone. The company plans a six-well development program in 2027 to lift production from the Highwood acreage to 3,000 barrels per day. Each well is budgeted at about C$5 million — a low enough unit cost that the program carries limited balance-sheet risk at current crude prices, though Obsidian has not published a formal breakeven figure.5
Combined with existing Belly River production, Obsidian estimates its total output in the formation could reach 7,000 barrels per day, making it the dominant producer in the Willesden Green area. By the company's own estimate, total field production across the formation runs between 10,000 and 13,000 barrels per day equivalent, which means a substantial portion remains in other hands. Rigzone's reporting identified Yangarra as one other active operator but did not name others.5
This activity fits within a wider shift in Canadian oil investment. Federal and Alberta provincial officials have advanced planning for a new West Coast pipeline that would add one million barrels per day of oil sands export capacity to the British Columbia coast, a project partly driven by the fact that 90% of Canadian crude exports previously flowed to U.S. markets, an exposure that became politically untenable following tariff threats from Washington. Northern Oil and Gas also entered Canada in May 2026, paying an initial CAD 350 million ($259 million) for a 25% stake in Duvernay shale light-oil assets from Parallax Energy.4,1
Across the Atlantic, the UK's upstream sector is consolidating rather than expanding capacity. Harbour Energy completed its $163 million acquisition of Waldorf Energy and its UK subsidiaries on July 13, 2026. The deal added 20,000 barrels of oil equivalent per day and 35 million boe of 2P reserves and lifted Harbour's stake in the Catcher field from 50% to 90%, concentrating the company's North Sea exposure rather than spreading it.3
BP went the other way. The company agreed to sell its 37.212% interest in the Bay du Nord deepwater field offshore Newfoundland to partner Equinor, describing the move as part of "continued portfolio simplification" and "strict capital discipline." Equinor is buying a pre-production deepwater asset whose returns depend on cost execution and oil prices years out.2
Whether Obsidian's 2027 program delivers the targeted 3,000 barrels per day will be the first real test of how repeatable the Belly River oil pay actually is. A C$5 million well cost leaves little room for geological disappointment. But if the formation delivers across the full 10,000-to-13,000 barrel-per-day range that Obsidian estimates, a play once written off as a spent gas field will have staged a more unusual recovery than it currently gets credit for.5
