Integrated Reservoir Modeling

This five day interactive and practical course will help participants to use geological modeling to produce realistic volumetric estimations for hydrocarbon reservoirs.  It will show how new operational data and revised interpretations, such as a new well or a recently discovered fault, can be identified and incorporated into models at any point in the workflow.

This course will introduce the procedures and workflow for building a 3D model, regardless of the software available to the modeling team.  In other words, this will be an attempt at a best practice approach to a complex and varied workflow. There will be a particular emphasis on integrating static and dynamic reservoir properties with the geological facies model.  Exercises will be done using industry standard modelling software (PETREL), although it should be emphasized that the purpose of the course is methodology and not software operation.

Relevant industry case studies and practical applications will be reviewed throughout the course.  Participants will gain an understanding of the key challenges associated with building effective 3D reservoir models from interpretation and design to quality assurance and optimization of results.

Participants will understand the science and workflows behind building consistent 3D reservoir models including fluid distribution, permeability, compartments and volumetric estimation. They will learn how integrate data from cores and logs and how to upscale this data into geological and flow simulation models that will have a high impact on field development and production scenarios.
