Mapping program 2011 - 2014

Guarantee the continuity of current programs

Shift to (other) application areas of actual needs/questions and data needs

Upgrading and actualisation of knowledge needed for geothermal energy, CCS

and unconvential gas: Specific reservoir layers !!!

Onshore: a. ultra-deep and b. shallow

Emphasis on dynamics (processes, prospectivity and forecasting/planning)

Thematic policy support
