Course description
A Practical Introduction to Geological Interpretation of 3D Seismic Data - training course
This course raises the quality of geological thinking using the medium of 3D seismic data. It enables seismic interpreters to improve their seismic interpretation skills through a better understanding of the nature and limitations of seismic data. It describes modern techniques for eliciting structural and stratigraphic information from those such and includes many examples of seismic data in a variety of geologic settings.
This is a five-day classroom course with lecture sessions that will include many real data examples supplemented by hands-on practical exercises working with paper seismic sections.
Suitability - Who should attend?
Graduate-level geophysicists and more experienced subsurface professionals from other disciplines (geology, reservoir engineering) who require of a working knowledge of seismic interpretation techniques.
Outcome / Qualification etc.
Participants will learn to:
- Analyse seismic data quality to ascertain what reliability of interpretation is possible, accounting for issues of resolution, positioning errors, multiples and imaging artefacts.
- Employ modern techniques for structural and stratigraphic interpretation of 3D seismic data which honour geological principles.
- Verify the bandwidth and phase of a seismic dataset and illustrate their implications for interpretation and well calibration.
- Determine which seismic events to map by identification of key surfaces and packages.
- Use seismic facies analysis to extract information about depositional processes.
- Reconstruct geological history and establish the presence of unconformities.
- Distinguish between a variety of geological settings as exhibited on in 3D seismic.
- Question what image problems may result from complex structure.
- Examine seismic data to identify potential direct hydrocarbon indicators (DHIs) and fluid contacts.
