Essentials of Rock Physics and Seismic Amplitude Interpretation - 3 Days Course

September 19 - 21, 2023
3 day in_person course: This highly acclaimed course is a must for all geoscientists wanting to understand rock physics principles, their application to amplitude interpretation (including AVO reflectivity and elastic inversion products) and how they can be applied to assess drilling risk. Dr Rob Simm of Rock Physics Associates Ltd has granted Ikon Science the rights to deliver this course by our approved instructors.

Temporal resolution, principles of net thickness estimation, resolution vs detection (sections and maps).
Well Ties
The well tie process, log calibration, the importance of wavelet shape, problems with assuming phase and timing, well seismic matching (White’s) and the ‘adaptive’ techniques.
Deriving Inputs for Seismic Models
A perspective on practical rock physics and rock physics models utilizing log data, log editing, the inputs for Gassmann’s equation and fluid substitution, examples of different rock physics models and the concept of lithology substitution.
