Course Format

This course is part of the EAGE Education Tours (EET), the flagship education programme of the Association. EET courses are specifically designed to bring members the latest developments in geoscience and engineering through experienced instructors from industry and academia. In 2020 we are proud to introduce EET courses that can be attended remotely over two half-day sessions. Participants will have the possibility to interact live with the instructor and ask questions. EET courses are supported by the EAGE Education Fund for the benefit of members, who can register for special discounted fees.

Education Packages

To help you save on registration fees and better organize your learning path, we are offering Education Packages for all Interactive Online Short Courses and Online EETs. The packages are valid for a period of 12 months and give you access to 3, 5 or 10 courses of your choice.

Course Description

Seismic surveillance for reservoir delivery includes the use of time-lapse seismic surveys and other seismic technologies which may inform us about the status of the reservoir and the activities related to the development of the reservoir.

Time-lapse or 4D seismic data provides snapshots of a producing hydrocarbon reservoir and its surroundings. The benefit of this technology in monitoring fluid and pressure changes and to point out bypassed oil or un-drained compartments has been well documented since it early starts 40 years ago. While the 4D seismic technology is still undergoing continuous development, the technology has become a routine tool for maximizing value and supporting safe operations in many producing assets.

In this course we will start out with historical perspective on the use of 4D seismic application while aiming to give a snapshot and recent example on the status of the technology. Examples from the Valhall field, hosting the world first fieldwide permanent seismic array for reservoir monitoring (PRM) was a primary focus for of the initial EET 6 course and will still be the key reference to illustrate the potential of seismic monitoring data and to articulate issues related to interpretation and integration. Insights and experience from subsequent PRM installations as well as examples of more recent use of marine towed streamer and OBN will be included to illustrate the technology status, trends and field specific applications. Use of seismic surveillance information to support reservoir management, new well delivery and base management will be a central part of the presentation. The focus will be on time-lapse seismic monitoring surveys acquired using conventional seismic sources. Examples of passive monitoring, utilizing ambient noise or induced micro-seismicity, will also be discussed.

The course will provide context on what is driving the dynamic changes linked to producing a hydrocarbon reservoir and what we should expect to observe using seismic technologies in a varied geological setting. It will address key issues that impact the feasibility of time-lapse seismic and evaluate established methods including examples how seismic monitoring techniques can be used to understand possible production induced effects outside the reservoir, often linked to geo-mechanical changes.

Prior to the course, participants will receive the link to the e-book of the course.
