Harbour Energy Named Operator of Mexico's Zama Oilfield

Britain's Harbour Energy has been appointed operator of Mexico's Zama oil field, following agreement from project partners Pemex, Grupo Carso, and Talos Energy. The announcement comes shortly after Harbour's $3.2 billion acquisition of LLOG, which provides entry into the Gulf of Mexico market.

Harbour holds a 32.22% operating interest in Zama, with Mexican state oil company Pemex as the previous operator. Project partners will have the option to appoint key personnel to Harbour's Zama project team.

Discovered in 2017, Zama represents one of Mexico's largest private company oil discoveries in decades, containing approximately 750 million barrels of oil equivalent resources. Once operational, the field is expected to significantly contribute to Mexico's domestic energy supply and Harbour's production levels, according to Gustavo Baquero, Harbour's Managing Director for Mexico.

This appointment positions Harbour as operator of two major Mexican offshore oil projects. The company also operates the nearby Kan field, where it maintains a 70% interest alongside TotalEnergies.

The development strengthens Harbour's position in the Gulf of Mexico region, complementing its North Sea operations and recent LLOG acquisition. The Zama field's substantial reserves represent a material growth opportunity for Harbour's production portfolio while supporting Mexico's energy security objectives.
