Fracturing Pressure Analysis
The course objective is to provide students with theoretical and practical expertise to acquire both the reservoir transmissibility and pressure required for fracturing production optimization and the correct insitu state of stress controlling frac placement. The course covers the integration of fundamentals of rock stresses, pressure diffusion, leakoff, poroelasticity, closure analysis( GPlot) , After Closure analysis (minifalloff method) applied to conventional fracturing models and their calibration using field data. Applicability to extremely tight reservoir (shale) are discussed.
