Deploying Extensive Experience of the Oil and Gas Assets of Equatorial Guinea

For over 20 years, Tetra Tech provided integrated technical and operational support to the Equatorial Guinea Ministry of Mines, Industry, and Energy. During that time, our team built a unique understanding of the country’s oil and gas assets.

Deep expertise brings a unique perspective

Over the 20 years that Tetra Tech supported the Government of Equatorial Guinea, our team built up a thorough understanding of the country’s oil and gas assets and developed expertise in all aspects of the producing assets. This deep understanding enables Tetra Tech to bring a unique perspective to the oil and gas sector in this region, which adds value to our clients’ projects around the globe, but particularly in Equatorial Guinea where there are still opportunities for development as the existing assets continue to produce.

The Equatorial Guinea petroleum industry’s rapid development

Significant expansion of the petroleum industry in Equatorial Guinea started in the 1990s after the discovery of the Alba gas condensate field in 1983, and the subsequent discovery of the Zafiro and Ceiba fields.

Rapid development continued throughout the 2000s with the discovery of the Okume field complex and the Aseng field, and the early 2010s with the Alen field. Vigorous exploration and rapid development resulted in daily production rising from less than 5,000 bbl/d in 1992 to a 2012 average that exceeded 410,000 bbl/d, declining to 114,000 bbl/d in 2021.

Tetra Tech, heavily involved in the petroleum sector in Equatorial Guinea during this time, was able to assist the Government of Equatorial Guinea and Ministry of Mines, Industry, and Energy to develop the sector into the driving force behind the ongoing growth in Equatorial Guinea’s GDP and the country’s rapid development.
