Fractured Basements

Fracture analysis of Palaeozoic and crystalline rocks

September 27-October 1, 2021

Crystalline basement formations, especially granites, are increasingly being explored for hydrocarbons and also for geothermal power or heat projects. Other basement formations such as Devonian carbonates or Cambro-Ordovician quartzites also host reservoirs. This field trip aims to bring together geoscientists and engineers from these parallel industries to discuss and share experience and knowledge.
