Petroleum geologists, explorationists, petrophysicists, geophysicists and engineers involved with exploration, appraisal and development of fractured reservoirs.
- Introduction to fracturing: Basic principles, fracturing in tight reservoirs- Fracture terminology- Fracture mechanics: Stress and strain, deformation mechanisms, brittle deformation, propagation and arrest of fractures- Fracture classification: Joints, shear fractures, compression fractures, stylolites- Controls on fracture formation: Lithology, sedimentary structures, bed thickness, mechanical stratigraphy, bedding planes, tectonic setting, palaeostress, subsidence and uplift history, proximity to faults, position in a fold, timing of structural events, mineralisation, fracture evolution, orientations of in situ stresses, fluid pressure, depth- Fracturing in different lithologies- Fracture identification: Seismic, wireline logs, core, outcrop, satellite imagery- Data collection and analysis: Fracture orientations, scaling relationships, fracture spacing, temporal relationships, frequency and density calculation- Fracture analogues: Kurdistan, Bristol Channel- Fracture modeling: Modelling approaches, modelling platforms, discrete fracture network modelling and modelling considerations- Basic fractured reservoir engineering: Basic principles, well testing and productivity, fluid flow, reservoir stimulation, recovery mechanisms
