P626 FRACTURE ORIGIN MORPHOLOGY AND RESERVOIR PERFORMANCE IMPROVEMENT – EXAMPLE OF THE MAASTRICHTIAN CHALKY LIMESTONES IN TUNISIA 1 HABIB TROUDI 1 HASSEN EL EUCHI 1 and PAUL TREMOLIERES 2 1 ETAP 27 bis Av. Khéreddine Pacha 1002 Tunis Tunisia 2 Consultant Introduction Because of the drastic increase in oil/gas discoveries where natural fractures play an important role in production (North sea Middle east USA North Africa …) focus on fracture studies with an ultimate goal of fracturing on subsurface fluid flow and subsequent reservoir performance is of paramount importance in the reservoir evaluation and management. This interest manifested itself by
