New trends Policy support + knowledge for sustainable solutions use deep subsurface (geothermal energy, CO 2 - storage) Regional inventory “new” gas prospects (shallow gas, gas shales, tight gas, CBM, …) Climate & Safety (prediction, risks and human impact) Spatial planning (VRODO) 10 januari 2011 M Bouman TNO Nieuwe huisstijl 4

Mapping program 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 10 januari 2011 M Bouman TNO Nieuwe huisstijl 5
