Zama field

Grupo Carso is securing a significant interest in the field ahead of final investment decision.

The massive offshore field inches closer to first production with the filing of the unit development plan with Mexican regulators.

Mexico’s Ministry of Energy has completed the unitization resolution between the blocks that share the Zama reservoir.

The Zama field was once considered the ideal result of Mexico's energy reforms that sought to bolster the country's oil and gas output by inviting private companies to participate in the energy sector.

The Quesqui field is expected to be the biggest onshore find in Mexico since 1987.

Operator Talos Energy now believes Zama’s gross recoverable resource lies in the upper half of its pre-appraisal estimate of 400–800 million BOE. The consortium is working toward a 2020 final investment decision on the project.

DEA Deutsche Erdoel is buying Sierra Oil & Gas, giving the German operator stakes in six new blocks off Mexico—including the Zama discovery, where appraisal drilling is now under way.
