Drilling, stimulation and reservoir assessment > As it is already partly expressed in the FP7 work program, researches should • define conceptual models for irreversible enhancement of permeability of the reservoirs • analyse the distribution in time and space of the magnitude of seismic events in order to improve the 3D imaging of the fracture system and stress field • set requirements for seismic monitoring and recommend management strategies for prolonged field operation, • provide a methodology for the estimation of site-specific seismic hazard prior to development of potential sites for EGS. > The induced earthquake in Basel on the 8th December 2006 reveals the urgent necessity to fill the gap in knowledge about this matter > 8 Drilling cost effectiveness and feasibility of high-temperature drilling, Reykjavik, 2-5 July 2007
