Quantitative Modelling and its Application to Stratigraphic Interpretation and Seismic Reservoir Assessment
|
This course is based on theory that mathematically relates log observations of rock type, porosity, and fluid content to compressional and shear wave velocity. With the basic model, participants are able to predict the effect of lithology or fluid variation on the seismic trace, inverted seismic trace, or AVO measurement. The approach is suitable not only for seismic interpretation, but for log editing and creation of synthetic logs. The effect of bed thickness and tuning models, approaches to seismic inversion, and applicability of AVO studies are reviewed based on the basic rock property model. An interpretation model is presented that incorporates geological and geophysical mapping procedures for reservoir evaluation and stratigraphic mapping. This course content concentrates on linking rock property information from the borehole logs to seismic observations. The course considers the log input and the basic seismic trace, seismic attributes, inversion of seismic traces, and amplitude versus offset measurements. No single seismic or log measurement is treated as the "truth", instead the merits of each observation are considered. Basic mathematical concepts are simplified to monograms or spreadsheets that are available with the course notes in .wks format. These ensure that the concepts of the course are replicable. |
