Advanced Seismic Stratigraphy: 4-5 Days
Who should attend:
Exploration geoscientists who have a working knowledge of basic seismic stratigraphy and want to improve their exploration and development skills.
Course Organisation:
The course will comprise a mixture of core lecture-style presentations, to augment the major exercises which will run throughout the course. The aim is to provide the theoretical background in the lecture series which will provide the basis for undertaking the exercises.
Core Content:
During the course the following subject areas will be covered and discussed in order to provide a sound basis for the practical elements undertaken in the exercises.
- Review of seismic stratigraphy objectives.
- Comparison of "Vail" and "Galloway" approaches to sequence stratigraphy .
- Shallow water siliciclastic sequences.
- Deep water siliciclastic sequences.
- Carbonate sequences.
- Integrating high resolution micropaleontology and seismic.
- Fault modelling - creating robust fault geometries.
- Application of Waveform Analysis (amplitude, phase and frequency, velocity).
- Amplitude Variation with Offset (AVO; indication of lithologies, fluids, porosities and pressures).
- Geovalidation: Synthetics, Seismic Inversion and VSP.
Practical Exercises:
The practical exercises, drawn from examples around the world, will comprise a mixture of paper and software-based exercises which will allow the trainee to practice and experiment with the advanced methods being presented in this course. Exercises will be paper and software-based. The following will be covered in the exercises:
- Determine rock-fluid properties from waveform analysis.
- Geovalidate selected intervals using synthetic seismograms, seismic inversion and VSP.
- Create sea-level curves from micropalaeontology.
- Integrate micro-paleontological data and seismic.
- Generate seismic facies maps within a sequence stratigraphic framework.
- Constrain reservoir architecture from seismic: robust fault geometries and representative stratigraphic layering.
