THE GENERAL STRATEGY
The overall strategy of 2F2S is built around the knowledge that efficient predictions of producibility of tough gas plays, such as gas shales, tight sands or coal seams, can be only achieved a) by adopting a multi-scale approach (cover the 105-10-5m range) to understand the behaviour and transport properties of both natural and man-made fracture systems and intervening rock matrix under in-situ P-T-chemical conditions, and b) by consciously integrating the disciplines needed to link the multiple scales involved, i.e. numerical modelling studies, laboratory experiments and field observation and verification studies.
