Integrated Wellbore and Reservoir Analysis: From Pore to Well Test Scale

The goal is for participants to develop subsurface skills for integrated analysis of rock, pore, well test and fluids to solve problems associated with identifying and exploiting reserves. Experience gained will allow participants to apply tools for analysis of the underlying uncertainty and assumptions used in many reservoir analysis techniques. A subsurface integration process model is presented which provides a multidiscipline methodology for solving reservoir problems, from facies, petrophysical rock typing,flow unit and the basics of well test information for a better understanding of reservoir characterization and the input required for a reservoir mode
