Advanced Integrated Reservoir Analysis
The goal is for participants to develop subsurface skills for integrated analysis of rocks, pore and fluids and 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 model presents a thought process for solving reservoir problems, from petrophysical rock typing through log analysis. Various quick-scan and quick-look techniques are presented, and participants gain experience with these methods by completing applied exercises.
Reservoir issues such as drive mechanisms, recovery factor and scoping simulation models are demonstrated. Experience gained will allow participants to identify lithologic zones and fluid types from log data. Physics of the measurements along with practical theory will allow the student to follow simple procedures for the rapid and accurate interpretation of log measurements. Correlation to core and concepts of petrophysical rock type and advanced flow units will allow upscaling of log data to reservoir simulation applications.
Advanced interpretation concepts will be discussed which will provide the student with the tools to understand the limitations of data sets along with measurement requirements for effective reservoir development.
