QUANTITATIVE INTERPRETATION WORKSHOP PROGRAM
|
1. Introduction
2. Factors affecting rock velocities
- composition and mineral properties
- geometry
- stress
- fluids (Gassmann)
3. Multi-phase pore fluids
4. Acoustic fluid properties
5. Trend curves of rock properties
(exercise on trend curve derivation)
6. Seismic imaging velocity as an interpretation tool (exercise on derivation of trends including seismic imaging velocity)
7. Composite rocks and the laminated model
8. Theoretical seismic reflectivity and AVO(concentrate on small angle, small contrast approximation),(exercise exploring effects of rock
properties and fluids on seismic reflectivity)
9. Prediction of AVO with uncertainty from trends(exercise on deviation of range of reflection coefficients and
AVO response)
10. Estimation of fluid and lithology probabilities
- detection problem and best AVO attributes (when are multiple stack
amplitudes useful?)
- Bayesian framework
- BHPB DHI boost methodology
(exercise on application of DHI boost)
11. AVO calibration and well ties
(exercise on wavelet derivation)
12. Amplitude extraction an volumetric estimation
- one layer tuning model
- use of sparse spike seismic inversion
(exercise on amplitude extraction and volumetric estimation)
13.Lease sale exercise
(Given seismic data and well logs; teams will interpret data,
evaluate risk and volumetrics, then bid against each other.)
