Assala Energy
Assala Energy is an oil exploration and production company.
Assala Energy’s strategy is to invest in improving the production efficiency of our mature fields by streamlining our operations while reducing our carbon footprint.
This is how Assala fulfils its role: to provide the energy we need and therefore contribute to local and national socio-economic development.
Assala Energy takes its inspiration from its namesake.
The Gabon is one of the last refuges for African forest elephants. Assala is the local name given to these elephants. Their small size is the result of their successful natural adaptation to the dense environment in the equatorial forests, and allows them to move around with ease and thrive.

Inspired by our namesake, our model is based on flexibility, innovation and creativity so we can adapt and progress in an ever-changing environment.
Assala is one of the biggest oil producers in Gabon.

Assala has six production licences:
Rabi Kounga II, Toucan II, Bende M’Bassou Totou II, Koula/Damier, Gamba/lvinga and Atora II. We also have a stake in a production licence we do not directly operate (Tsiengui).

In 2019, four of these onshore production licences were renewed for 25 years, and the acquisition of three onshore exploration licences (Mutamba-lroru II, Nziembou II and Ozigo II) has opened up new development opportunities.

Assala Energy’s business strategy is to increase production safely while ensuring integrity. This means maximising the time the equipment is used, ensuring high-quality maintenance, and reducing our emissions and the environmental footprint of our operations in order to unlock the inherent potential of our production assets.

Our economically strong development projects are tailored to our objectives and meet our risk management criteria. Our primary concerns are asset integrity, workovers, well interventions, robust management of fuel tanks, optimisation and additional drilling.

The aim is to invest in our company’s performance and therefore the production of the energy we need. Assala can in turn contribute to socio-economic development and the Paris Agreement on greenhouse gas emissions.

The companies in the group put their 520 employees at the forefront of their business. We empower our employees to reach their full potential while applying best practice safety standards.
Assala Energy supports fair and equitable access to job opportunities.
The Assala Energy management team boasts extensive experience in the oil sector, particularly in Africa.

David started the Assala Energy project in 2016 on the back end of the 2014-2016 oil crisis.
He brought together a team of professionals, with whom he had worked during his career. Chosen for their expertise in capital- and debt-raising, ESG (Environment, Social & Governance), mature assets redevelopment, and exploration, they have together, under his leadership, built on their decades of experience to ensure the long-term future of Assala.

During this time, Tullow achieved reserves replacements of over 100% in Gabon and carried out new-country entries and high-profile exploration projects throughout the region. He was then promoted to Senior Advisor to Tullow Oil’s Founder & Chief Executive Officer, troubleshooting the company’s contractual, fiscal, commercial and business issues across the African continent.
