Harbour Energy successfully appraises Kan Discovery in Mexico and significantly increases its estimate to 500 million barrels of oil-in-place
08/05/25
Operator Harbour Energy is pleased to announce the successful appraisal of the Kan discovery located in Block 30 in the Salina del Istmo Basin, offshore Mexico. Harbour holds a 70% interest in the block, alongside partner TotalEnergies (30%).
The appraisal campaign, completed on time and within budget, validated volumes above pre-drill P50 estimates. Based on new data from the appraisal well, Harbour has significantly increased its oil-in-place estimate for Kan from 200–300 million barrels to 500 mmboe of oil-in-place, with updated gross recoverable resources of approximately 150 million barrels — a 50% increase over initial projections.
“This successful appraisal campaign reflects careful technical planning, collaboration and execution, and marks a major milestone for Harbour Energy in Mexico,” said Bernhard Siethoff, Vice President of Exploration and Subsurface, Mexico. “It validates the quality of the Kan discovery and demonstrates our ability to safely and efficiently deliver high-value resource growth. The results open a clear path towards potential development,” added Sergio Calles, Block 30 Exploration and Appraisal Manager.
This outcome strengthens Harbour Energy’s strategic position in Mexico and supports its broader commitment to regional energy security through responsible and efficient resource development.
As Kan advances, Harbour will continue working closely with government authorities, communities, and stakeholders to deliver value for Mexico—fostering transparent dialogue, promoting local content, and aligning development with national priorities and environmental stewardship.
