Rodney William Calvert worked for Shell International Exploration and Production, in the exploratory research team. He obtained a physics degree from Oxford in 1966 and did his first time-lapse work measuring continental drift in Iceland as part of a Ph.D. program in 1969 before joining Shell. He held a series of interesting jobs around the world as a Shell geophysicist, including the position of chief scientist of geophysics. He was a seismic processor in The Hague, where he developed techniques for making band-limited seismic impedance sections to tie well data. In 1971, he worked jointly with Texas Instruments, developing software for the first seismic supercomputer. In 1975, Calvert became the seismic processing manager for Shell Malaysia, where he developed prestack Kirchhoff migration for solving steep dip problems. He transferred to the United Kingdom in 1979 to manage Shell's early 3D processing and acquisition efforts in the North Sea. In 1985, he became manager of geophysical research at Shell's laboratory in Rijswijk.
A highlight of Calvert's career was his posting to Canada in 1989, where he managed geophysical technology and developed an addiction to backcountry skiing. In 1993, he transferred to Houston and then back to the Netherlands to manage seismic software development and research into multidisciplinary modeling and interpretation. Calvert later worked at improving 4D methods and uses at Shell's Bellaire Technology Center in Houston, Texas. Calvert died at his home in Houston after an extended illness on November 22, 2007.
2005 SEG/EAGE Distinguished Instructor Short Course
Insights and Methods for 4D Reservoir Monitoring and Characterization
4D can give major returns if applied properly. However, it is still a rapidly evolving technology. Participants in this one-day course come away with a basic understanding of the issues leading to success and failure and the methods to ensure success.
The course will address the following questions:
- What methods of seismic 4D monitoring are appropriate for different types of fields and production mechanisms are appropriate for? What questions can 4D answer? Are there any alternatives?
- What are the seismic quality requirements and how can we assure they are sufficient? What 3D problems can we difference away to get good 4D?
- There are now more and more options available for seismic acquisition with streamers, OBC, OBS and down-hole possibilities. How do we make the best choice for quality and price? Some real breakthroughs are now possible.
- What should we measure from our data? What are the important reservoir engineering questions? What do people mean by "quantitative 4D" and what is possible with petrophysical and reservoir engineering co-operation?
- How can we update a reservoir model using 4D data and 4D history matching?
- How should we make 4D monitoring an integral part of field development and management? How might this change our industry?
Participants will be able to take home and use the answers and methods discussed in this course.
