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.

Financial Modeling Program

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. Interested? Contact us!

Using interoperable data formats, clear editorial standards, and drawing on public domain data, OpenOil creates network graphs of companies, executives, assets, and the relationships between all of them.
