    Petrel Uncertainty Analysis and Optimization Fundamentals - RILS (Remote Instructor Led Series)

    This is a Remote Instructor Led Series (RILS) training. The remote classroom delivery is a modality that takes advantage of the instructor led training content, while allowing the same content to be delivered remotely. All training sessions will be delivered online with no face-to-face classroom attendance.

    Subsurface uncertainties assessment is an essential phase in any field development strategy. These course learning contents are designed to provide the reservoir engineers with the concepts and necessary application skills for uncertainty assessment quantification and optimizations using Petrel workflows tools. There are  several ways to analyze and quantify uncertainties in Petrel, whether those uncertainties are associated with a single modeling process, such as a hydrocarbon contact
    depth in a 3D static model, or a combination of several interdependent processes ranging from seismic to simulation and economic forecasting.

    This course discusses how to use Petrel Uncertainty and optimization tool to perform sensitivity analysis, uncertainty assessment, and optimization (history matching). It also covers the Proxy modeling concepts, benefits, limitations and its applications using the available workflow tools in Petrel.

    The course exercises are blended to incorporate learning of the software skills and its application using practical reservoir engineering technical challenges scenarios in the context of reservoir studies. The theory behind each software technology features are explained and practical exercises provided in each module to allow you to practice using these features described in the module.

    The course will be delivered in five (5) sessions lasting ~ four (4) hours each. An intensive agenda also implies homework after each session. Hence full-time commitment is expected from participants.

    Each student will need the following to attend:

    1. Windows-based PC*
    2. USB Headset
    3. Internet Access capable for 720HD video-streaming
    4. Second monitor or tablet (highly recommended)
    5. Webcam (highly recommended)

    *Hands-on exercises will be performed using locally installed Petrel and Eclipse software; hence client machine must satisfy min. requirements. Alternatively, practical sessions can be accessed through DELFI Cloud Environment (subject to availability).
