Seismic Attributes and AVO for Reservoir Delineation
Duration: 5 Days
Target Audience: Geophysicists, Geologists, Reservoir Engineers, Interpreters
Delivery Mode: Classroom / Virtual with Practical Exercises on Real Datasets
Level: Intermediate
Course Overview
This program focuses on the theory and application of seismic attributes and AVO (Amplitude Versus Offset) analysis for reservoir characterization and delineation. Participants will learn how to extract and interpret seismic attributes, understand AVO fundamentals, and apply these techniques to identify lithology, fluids, and depositional environments.
Day-by-Day Outline
Day 1 – Seismic Attributes Fundamentals
- Definition and classification of seismic attributes (instantaneous, geometric, spectral)
- Key concepts: amplitude, phase, frequency, dip, coherence
- Attribute sensitivity to lithology and structure
- Attribute workflows in interpretation projects
- Exercise: Generate and visualize basic attributes from a sample dataset
Day 2 – Advanced Attributes for Structural Interpretation
- Geometric attributes: dip, azimuth, curvature
- Fault and fracture detection with coherence and variance attributes
- Stratigraphic interpretation with spectral decomposition
- Seismic texture and pattern recognition
- Workshop: Identify faults and subtle stratigraphic features using attributes
Day 3 – AVO Theory and Fundamentals
- Amplitude variation with offset: physical principles
- Shuey’s equation and AVO classes (I-IV)
- Rock physics link to AVO response
- Data conditioning for AVO analysis
- Exercise: Create offset gathers and examine AVO anomalies
Day 4 – AVO Analysis and Interpretation
- AVO intercept and gradient plots
- Fluid and lithology indicators from AVO responses
- AVO modeling from well logs
- Limitations and pitfalls in AVO interpretation
- Workshop: AVO crossplot interpretation for fluid and lithology discrimination
Day 5 – Integrated Attribute and AVO Applications
- Combining attributes and AVO for reservoir delineation
- Case studies of successful reservoir detection
- Seismic inversion overview and elastic attributes
- Uncertainty assessment in attribute and AVO interpretation
- Capstone Project: Delineate a reservoir using multi-attribute and AVO workflows
