Harmattan (Canada)

Cardium light-oil and Mannville liquids-rich gas assets at Harmattan in the Western Canadian Sedimentary Basin, ~80km north of Calgary, Alberta, acquired through the 2022 TransGlobe combination. VAALCO held a 100% working interest in a large oil battery and a compressor station processing most oil volumes, with gas processed at a third-party plant. The Canadian assets were classified as held for sale at December 31, 2025 and divested in February 2026 (Canada Asset Divestment, ~US$25.5 million), representing VAALCO's complete exit from Canada; FY2025 production and year-end reserves are reported here as held during the year. Production was 32% oil, 36% gas, 32% NGL.
