Distinguished Instructor Short Course 1998
Time-Lapse Seismic in Reservoir Management
This course, intended to appeal to a wide audience, will bring participants up to date with the current state of the art and will enable them to make decisions involving the use of the method.
It will cover the rationale and driving forces behind "time lapse seismic" by examining the limitations of existing methods of tracking fluid flow between wells and will examine those reservoir properties which change with time and what might be observed on seismic data as a function of elapsed time, together with those things which may also change which we would prefer to remain constant.
Rock physics is the link between reservoir depletion and seismic observations. In this area key success factors, key calibration requirements, and key uncertainties will be addressed.
The repeatability of seismic data and the use of "legacy" data sets will be discussed, together with a review of the seismic data acquisition schemes and data processing requirements for time lapse analysis. Analysis and interpretation options will be investigated, as will the risks and value of this new technology.
A representative selection of industry case histories will illustrate many of the above points and some of these will be worked through in detail. The course finishes by noting some remaining challenges.
