    Introduction to 4D Seismic in Production Management

    Time-lapse (or 4D) seismic is an integral part of reservoir management in many major and medium size oil companies. Successful case studies have demonstrated how using 4D seismic can overcome reservoir engineering challenges. This course provides an overview of the utilization of 4D seismic in addressing reservoir management strategies. The 4D course will be delivered in 3 days and covers 1D to 3D modelling and 4D reservoir characterization. The course will be given in a conventional classroom presentation in modular form. Discussion and interaction with the instructors throughout this time is encouraged.

    This course is designed for geoscientists with an understanding of basic seismic theory. It aims to train students in 4D seismic related topics so that they can get involved in performing 4D seismic studies and provide reservoir management solutions. The audience should come away with a broader understanding, and specific working tools, for the use and interpretation of 4D seismic.

    No software will be used in this course; case studies will be presented and discussed.
