The course will cover the various seismic attributes, including amplitude variation with offset AVO attributes, that are used in reservoir geophysics and look at their application to time-lapse seismic. The course will also look at the application of seismic inversion in reservoir geophysics. Participants should acquire knowledge of the basic principles underlying modern reservoir geophysics and have knowledge of the latest terminology and technology in the field. They will acquire hands on experience in the use of rock physics and creating synthetic seismic data to examine the effects of changing reservoir geometry and fluid content.
They will also acquire practical experience using various attributes in quantitative interpretation on real well and seismic data.
