Dynamic Subsurface Imaging: 4D Seismic and Reservoir Monitoring Training Course

Introduction

As oil and gas fields mature, understanding the dynamic changes occurring within the reservoir due to production and injection activities becomes paramount for optimizing recovery and extending field life. Traditional static reservoir models provide a snapshot, but 4D seismic (time-lapse seismic) offers a revolutionary approach by imaging the subsurface at different points in time. This allows geoscientists and engineers to directly observe fluid movement, pressure changes, and reservoir compaction, providing invaluable insights for proactive reservoir management.

This intensive training course is meticulously designed to equip participants with a comprehensive and practical understanding of 4D seismic and its application in reservoir monitoring. From exploring the fundamental principles of time-lapse seismic data acquisition and processing to mastering the interpretation of 4D seismic attributes, integrating with other surveillance data, and leveraging these insights for production optimization, you will gain the expertise to manage dynamic reservoirs effectively. This empowers you to enhance hydrocarbon recovery, reduce operational risks, and strategically contribute to the efficient and sustainable production of energy resources.
