Germany’s Dea has completed the acquisition of Mexican independent Sierra Oil & Gas, giving it a 40% stake in Talos Energy’s large Zama oil discovery plus interests in five offshore exploration tracts.

The deal has been approved by Mexico’s National Hydrocarbons Commission and the Federal Economic Competition Commission.

Dea chief executive Maria Moraeus Hanssen said the deal “is a fantastic opportunity for us to become a very serious player” in Mexico, with the two players now consolidating their country interests to create a new unit.
