Hampson-Russell Seismic Lithology & AVO Workshop
November 22 - 26, 2010 (5-Day Workshop)
UNIT 1: GEOVIEW & eLOG - Foundation
- Unit 1 is a foundation for all of the other units.
- Instructs the student on fundamental project set-up in Hampson-Russell software products including data loading, manipulation, and editing of common input seismic, horizon, and well log files.
- Consists of a combination of lectures and practical exercises using the GEOVIEW & eLOG modules. Practical exercises comprise 75% of the unit content.
- Well Log Data: GEOVIEW interface, data loading, third-party connectivity, depth-time tables, deviated wells, data viewing, check shot correction.
- Data Management: Log profiling, log type mapping, well path viewing, handling culture data, seismic and horizon data loading & editing.
- Log Editing: Using eLOG, log editing, cross-plotting, log maths, log transforms.
UNIT 2: STRATA - Seismic Inversion
- Unit 2 provides a detailed but largely non-mathematical overview of current seismic inversion methods.
- Instructs the student on the application of different inversion algorithms to various datasets.
- Consists of a combination of lectures and practical exercises using the STRATA module. Practical exercises comprise 60% of the unit content.
- Inversion Steps: Convolutional model & wavelets, synthetic-to-seismic ties, model building, inversion analysis for optimizing results, using varying inversion algorithms.
- Practical Inversion: Inversion QC, implications of an inaccurate impedance model, inverting seismic with AVO effects.
- Current Technologies: Model-based, sparse-spike, and AVO inversions.
UNIT 3: AVO - Amplitude Versus Offset Analysis
- Unit 3 provides a comprehensive look at the theory and application of the AVO method.
- Includes AVO case studies from a number of regions around the world.
- Consists of a combination of lectures and practical exercises using the AVO module. Practical exercises comprise 50% of the unit content.
- AVO Theory: Basic rock physics, Poisson’s ratio, Biot-Gassmann equations, Fluid Replacement Modelling, Zoeppritz equations, Aki-Richards & Shuey’s approximations, elastic wave modelling, intercept & gradient, anisotropy.
- Practical AVO: Why is AVO less than perfect, AVO processing considerations, enhancing subtle AVO features, dangers of pushing AVO too far, common pitfalls in AVO interpretation.
- Current Technologies: Lambda-Mu-Rho, elastic impedance, polarisation analysis, and AVO fluid inversion (AFI).
UNIT 4: EMERGE - Attribute Analysis
- Unit 4 is a comprehensive review of how to use seismic attributes to build robust relationships in the prediction of petrophysical well log data.
- Teaches the theory and application of linear, multi-linear, and non-linear (neural network) technology in well log prediction and seismic lithology classification.
- Consists of a combination of lectures and practical exercises using the EMERGE module. Practical exercises comprise 60% of the unit content.
- Attributes: Seismic attributes classification, combining optimal attributes to predict log data from seismic, cross-validation techniques, attribute training, transform application to input seismic data, neural networks.
- Practical Attribute Analysis: When to stop adding attributes, how to improve prediction quality, pitfalls in interpretation of the resulting volumes, predicting missing logs from other logs.
