Earlier this year, Harbour Energy successfully appraised the Kan discovery in Block 30 offshore Mexico, significantly increasing its estimate of oil-in-place to 500MMb. The company considers that this discovery could generate significant value for its shareholders and strengthen its position in Mexico, supporting its commitment to regional energy security through responsible and efficient resource development.
The Kan Field is located in the Cuencas del Sureste basin, approximately 20km off the Mexican shoreline. It is operated through a partnership in which Harbour Energy holds a 70% stake and TotalEnergies owns the remaining 30%. The field lies in shallow waters, with depths ranging between 50 and 100m. Its geological focus is on the Pliocene and Miocene plays, with the main target reservoirs situated in the Upper Miocene, where the initial discovery was made, as well as in the Mid and Lower Miocene and the Lower Pliocene formations. "Kan field is the largest discovery after the Zama field in Mexico in recent years," said Bernhard Siethoff, Vice President of Exploration and Subsurface for Mexico, Harbour.
The Kan-1 exploration well, initially drilled by then-operator Wintershall Dea in 2023, made the initial oil discovery. Harbour Energy began appraisal drilling operations for Kan in August 2024.
The Kan-1 exploration plan delivered promising results, with preliminary estimates suggesting that the discovery could hold between 200 and 300MMboe in place. The drilling encountered a series of complex oil-bearing sands, notable for the absence of a clear oil-water contact, with all sands classified as oil-down-to. Each sand formation was identified as having individual pressure compartments, highlighting the geological complexity of the find.
Building on these results, the Kan-2 delineation plan applied the learnings from the initial well and led to even more significant outcomes. Estimates of volumes increased to approximately 500MMboe in place, largely due to the identification of a substantial oil column in the lower system. The drilling campaign was also distinguished by its strong performance in health, safety, environment, and security, as it was executed without any recordable incidents or accidents. The well was completed on schedule and at a cost below budget, underscoring both operational efficiency and financial discipline.
The appraisal campaign, which was completed on time and within budget, validated volumes higher than pre-drill estimates. Based on new data from the appraisal well, Harbour's updated gross recoverable resources for Kan are approximately 150MMb, representing a 50% increase over initial projections.
