Integrated Reesrvoir Analysis - 2020-30H - RILS

This is a remote delivery of Integrated Reservoir Analysis that is focused on pore-geometry, petrophysical rock types analysis, applied capillary pressure and saturation height modeling.

This 5 day course consist of 10 three hour sessions for a total of 30 hours. Participants complete approximately 10 hours of applied workshops using Excel.

The goal of Integrated Reservoir Analysis is for participants to understand the concepts and develop subsurface skills to integrated analysis of rock, pore, and fluids from various sources.  

Participants gain an appreciation of working with various scales (micro to mega) to solve problems associated with identifying and exploiting reserves. Concepts 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 integrated methodology for solving reservoir problems, from facies, petrophysical rock typing, flow unit characterization and an introduction to capillary pressure saturation height modeling.

Throughout the course the participants are encouraged to think about "big picture" volume in-place, static modelling and dynamic reservoir simulation. The course is intended for particiants that are using petrophysical data to build reserervoir static models.
