The Zama oil discovery is located in Block 7 of the Sureste Basin off the shore of Mexico, at a water depth of approximately 165 m.
The shallow water Zama discovery, 1st announced in 2017 by a consortium of operator US Talos Energy (35 %), Mexico’s Sierra Oil & Gas (40 %) - later taken over by Germany’s Wintershall Dea and UK producer Premier Oil (25 %), is progressing towards FID after a 3rd-party resource evaluation upgraded reserves estimates to between 670 mln bl oe and 1.01 bln bl oe.
The field is estimated to contain P90 (high) and P10 (best) gross reserves, it mainly has light oil featuring API gravities between 28° and 30°, along with associated gases.
The Zama field is planned to be developed with 3 production platforms. Each platform installation will comprise a single jacket and topsides and will be able to support production rates of up to 100,000 barrels of oil per day.
The development will also feature a single drill centre with wells drilled from the platform. Produced oil will be transported via a pipeline to the Dos Bocas terminal located onshore, approximately 70km away from the project site.
1st oil is expected in 2022 and the offshore field is expected to produce 150,000 barrels of oil-equivalent a day (boed) by 2024, accounting for roughly 10% of Mexico’s total oil production.

Zama oil field
Estimated to hold up to 2 bln barrels of oil-equivalent, it is considered to be one of the world’s biggest shallow-water oil discoveries in the past 20 years.
