Concession Maps

Each area is the co-ordinates of an oil or mining project. Those highlighted lead through to relevant entries in our databases on contracts, concessions, production, reserves, costs and corporate groups involved. All data come from relatively authoritative sources: government or the companies.

Open financial models are the natural next stage of extractives governance. We are running a free mentoring program to develop financial models of upstream oil, gas and mining projects, with the aim of creating a worldwide network of practitioners from civil society, government or private sector.
