Rock Physics & Seismic Inversion – Quantitative Interpretation
Duration: 5 Days
Target Audience: Geophysicists, Petrophysicists, Quantitative Interpreters, Reservoir Engineers
Delivery Mode: Classroom / Virtual with Software-Based Exercises
Level: Intermediate to Advanced
Course Overview
This course provides practical skills in applying rock physics principles and performing seismic inversion to derive quantitative reservoir properties from seismic data. Participants will connect petrophysical rock properties with seismic responses, build rock physics models, and conduct both deterministic and stochastic inversions. Emphasis is on quantitative interpretation workflows for reservoir characterization.
Day-by-Day Outline
Day 1 – Rock Physics Fundamentals
- Key rock physics concepts: acoustic impedance, Vp/Vs, Poisson’s ratio
- Rock property controls: lithology, porosity, fluid, pressure
- Elastic moduli: bulk, shear, Young’s modulus
- Rock physics crossplots: density vs. velocity, AI vs. Vp/Vs
- Exercise: Build crossplots for lithology and fluid discrimination
Day 2 – Rock Physics Modeling
- Building Gassmann fluid substitution models
- Rock physics templates (RPT) and their applications
- Sensitivity analysis: effect of fluids, porosity, mineralogy
- Synthetic models for AVO analysis
- Workshop: Perform fluid substitution and predict AVO response
Day 3 – Seismic Inversion Principles
- Types of inversion: deterministic vs. stochastic
- Basics of post-stack and pre-stack inversion
- Wavelet extraction and seismic calibration
- Low-frequency model building
- Exercise: Apply deterministic post-stack inversion to a synthetic dataset
Day 4 – Advanced Inversion & AVO Analysis
- Pre-stack inversion workflows
- Simultaneous inversion and its advantages
- Elastic impedance and extended elastic impedance
