In western Congo, on the edge of the Atlantic Ocean, gas flares mark the landscape. They are the symbol of the controversial oil exploitation of the Franco-British operator, Perenco, specialised in so-called mature wells.
With a near-monopoly in the country's hydrocarbon industry, the multinational has set up operations in a natural area near Muanda, where it is the subject of 167 accusations of serious pollution by local associations, international NGOs and university researchers.
This report also describes the methods used by Perenco to ensure its impunity on environmental issues.
