• Partners agree on a Unit Development Plan for the world-class Zama discovery
  • Significant contribution to Mexico’s energy supply over the next 25 years
  • Production from the field of up to 180,000 barrels of oil per day
  • Integrated Project Team established

Wintershall Dea, Pemex (operator), Talos Energy and Harbour Energy have jointly agreed on a Unit Development Plan (UDP) for the Zama field in the Gulf of Mexico, which has now been submitted to the National Hydrocarbon Commission CNH (Comisión Nacional de Hidrocarburos) for review and approval. The consortium agreed on the formation of an Integrated Project Team (IPT), in order to pool the talents and competencies of all companies participating in the development of the oil field.

"The timely agreement on a tailor-made development concept is a great success for our international partnership in Zama”, says Thilo Wieland, Wintershall Dea’s responsible board member for Latin America. “We are thus on course to achieve our goal of developing the Zama field in the most efficient timeline and in the best possible technical way. Zama is a major project for Mexico and at the same time plays a key role in our global portfolio," Wieland underlines.

Zama is one of the world’s biggest shallow-water discoveries in the past 20 years and was the first discovery made by an international consortium in Mexico, in 2017. With its estimated gross recoverable resources of 600 to 800 million barrels of oil equivalent, Zama is expected to contribute significantly to Mexico’s energy supply over the next 25 years. The field is expected to produce up to 180,000 barrels of oil per day at peak, which represents about 10% of the current overall oil production in Mexico.

"The establishment of the Integrated Project Team brings many advantages to this comprehensive world-class development project," emphasises Hugo Dijkgraaf, Chief Technology Officer of Wintershall Dea. "It enables the targeted mobilisation of specific competencies from all participating companies, including from Wintershall Dea. I am convinced this will have a significant impact on the quality of the project and the efficiency of its execution. I wish the entire Zama team a successful start into this important project phase", says Dijkgraaf.

Wintershall Dea, together with operator Pemex, Talos Energy and Harbour Energy, will co-lead different work groups within the IPT. In particular, Wintershall Dea will co-lead the Project Management Office, as well as the work groups for Finance, Supply Chain, and Subsurface Characterization. Furthermore, Wintershall Dea will co-lead the engineering and execution of the work, related to the Onshore facilities.

Martin Jungbluth, Managing Director of Wintershall Dea in Mexico, adds: "We look forward to bringing Wintershall Dea’s international experience and the knowledge of our G&G experts, engineers and project managers to the Zama project. Wintershall Dea is committed to deliver the agreed Zama development concept and to bring the field into production as quickly as possible and in a safe and efficient manner.”

The agreed UDP envisages the installation of two offshore platforms and the drilling of 46 wells. The production is then to be transported to shore via two 68-kilometre pipelines, where it will be processed in new facilities, fully dedicated to the Zama project, located in the Dos Bocas Maritime Terminal, in Paraiso, Tabasco. The UDP minimizes greenhouse gas intensity by using best available technology, produced gas for onshore power generation, as well as best use of existing storage and transport infrastructure.

A final investment decision (FID) is targeted in the next year after the front end engineering design (FEED) studies have been finalized, when cost and schedule risks have been mitigated to the appropriate level, and with the major contracts ready to be awarded.

Wintershall Dea is the second largest shareholder in the Zama field after operator Pemex and holds, according to the Unitisation Resolution from March 2022, an initial participation of 19.83%, while Pemex holds 50.43%, Talos Energy 17.35% and Harbour Energy 12.39%.


Wintershall Dea set foot in Mexico in 2017. The company has started exploring for and producing hydrocarbons in Mexico in 2018. Since then, the company has managed to establish itself as one of the leading international upstream companies in Mexico, with interests in licences in all phases of the E&P value chain.

With a 50 per cent share, Wintershall Dea has been operator of the producing onshore Ogarrio oil field since 2018. The Mexican state company Pemex is a partner and holds the remaining shares. Currently, the company, together with its partners, is in the process of closing the acquisition of a 37% share in the producing Hokchi field. In addition, Wintershall Dea has material interests in ten offshore exploration blocks located in the Gulf of Mexico, three of them as operator.

As a European gas and oil company, we support the EU’s 2050 carbon neutrality target. As our contribution we have set ourselves ambitious targets: We want to be net zero across our entire upstream operations – both operated and non-operated – by 2030. This includes Scope 1 (direct) and Scope 2 (indirect) greenhouse gas emissions on an equity share basis. Wintershall Dea will also bring its methane emissions intensity below 0.1 per cent by 2025. We endorsed the World Bank’s Initiative ‘Zero Routine Flaring by 2030’ and continue to support the initiative aimed at eliminating routine flaring in operated assets by 2030. In addition, we plan to support global decarbonisation efforts by building up a carbon management and hydrogen business to potentially abate 20-30 million tonnes of CO2 per annum by 2040. You can find more about this in our Sustainability Report.

Wintershall Dea was formed from the merger of Wintershall Holding GmbH and DEA Deutsche Erdoel AG, in 2019. Today, the company employs more than 2,000 people worldwide from almost 60 nations.
