ONLINE: Reservoir Simulation Technologies (RES906)


    This course deals with various algorithms, concepts and the possible uses of reservoir simulators in creating dynamic reservoir models. Focus is on generating stable and efficient simulation models that will minimize numerical errors and enable reliable predictions. Black-Oil and compositional model formulations as well as different grid types and solution techniques are presented to improve understanding of numerical reservoir simulation. Assumptions involved in different simulation features, extension or formulations and their influence on the results are discussed. Typical input data with associated uncertainties are presented, industry standard workflows from initialisation to history match and predictions are discussed.

    Course Structure: 12 modules of 1½ hours each, delivered over 4 days
    Each day will consist of 3 modules of 1½ hours, incl. a 15 min break.

    Course Level: Skill
    Duration: 4 days
    Instructor: Leonhard Ganzer

    Designed for you, if you are...

    • A reservoir engineer or in possession of skills in reservoir engineering
    • Interested in improving your understanding of reservoir simulation

    How we build your confidence

    Technologies used within reservoir simulators are explained by simple examples and slides. Reservoir simulation will be no black-box anymore. You will be encouraged to engage in discussions on your experience with simulation studies. Best practices and simulation artefacts are explained with examples useful for your projects. Exchange among participants during the course is stimulated to optimise the learning event.
