Course Description

The course introduces engineers, geologists and geoscientists to both the fundamental theory and practice of reservoir description and modeling for reservoir management. This course covers the fundamental concepts of reservoir description and modeling using geostatistical techniques. It is an introductory course with emphasis on the principles and practice of integrated studies and uncertainty analysis. Upon completion of this course, you should be able to (l) make decisions on when and where to apply reservoir description and modeling to support reservoir management, (2) understand the methodology of integrated studies (3) select the appropriate reservoir description and geostatistical modeling tools (4) analyze and QC data for reservoir modeling, (5) understand variogram analysis, kriging and stochastic simulation, integrated studies, uncertainty analysis; and (6) recognize the limitations and opportunities for reservoir modeling.
