Reflection Seismic for Geologists

2018-2019
Dit vak wordt in het Engels aangeboden. Omschrijvingen kunnen daardoor mogelijk alleen in het Engels worden weergegeven.

Doel vak

Understanding the fundamentals and limitations of the application of
reflection seismic to describe geology in the subsurface at depths of
200 m - 6 km.
This includes,
- Seismic Sequence Stratigraphic interpretation
- Seismic Stuctural interpretation
- Seismic Acquisition and processing principles and potential problem
areas
- Calibration with petrophysical information/synthetic seismogrammes and
potential problems
- Time Depth Conversion methods
- Modern Techniques, Volume interpretation, Use of Special Attributes
- Examples/Special Case studies (4D time lapse, use of Seismic
inversion)
In an extensive workstation Exercise (A/B), the theory will be applied
to a real 3D dataset, using an industry interpretation software package.
The Exercise part of the course is done by Teams. Teamwork is essential
in this type of work and will also be gauged during the assessment.

Inhoud vak

This Course is part of the Lecture Stream "Subsurface Resourcing" which
contains a series of elective courses that prepares for activities in
the subsurface (geothermal, CO2 sequestration, hydrocarbon exploration
and production). Many examples of successful techniques, originally
developed for the oil and gas industry, need also to be applied
elsewhere in order to achieve safe and accurate operations.

Assuming a basic knowledge of the principles of reflection seismology,
this course provides a modular programme with hands-on experience on
interpreting seismic 3D data and integrating data from well logs,
principles and interpretation of reflection seismic data and geology.
Special attention will be paid to pitfalls in data acquisition,
processing and interpretation. During the course standard methodologies
will be applied used in the industry.
The course consists of,
• - Introduction to seismology. The introduction will cover the
technical
and methodological principles of reflection seismology. Special emphasis
will be on the recognition of processing
errors and distinguishing them from geological information contained in
the seismic images.
• - – Structural interpretation. Students will learn how to interpret
basic geological features, such as strata relationships, faults and
folds as well as the reliability of seismic interpretation at various
scales;
• - – Seismic Sequence Stratigraphy entails the extraction of
stratigraphic, sedimentological and basin evolution information from
seismic data. This information can be used in exploration and basin
analysis to derive regional
analysis of sedimentary basin-fills in order to construct models for
gross lithology prediction (Students should review the principles of
sequence stratigraphy, acquired during their BSc courses);
• •- – Interpretation on workstation. Students work on a case study
using standard workstation methodologies and learn how to handle,
visualize and interpret 2D and 3D seismic data using a standard
industrial software package;
• - – Advanced seismic interpretation – This section will show examples
of recently developed techniques in 3D seismic information analysis.

Onderwijsvorm

The course uses two different methods: •
- Oral lessons, where the lecturer presents various topics. Students
must be aware that the content of this course is difficult to find in
textbooks. Therefore, understanding the handouts is essential. Our
advice is to attend all oral lessons. The exam will test the theoretical
knowledge and contributes 50% to the final score.
- Practical Exercise A/B. The practicals are done in Teams. Attendance
of the practicals is compulsory. By the end of the course, students
present the team results in an oral presentation as well as in a report.
The results from the presentation and report contribute the remaining
50% to the final score.

Toetsvorm

The final mark is made up by 50% from the results of the exam which will
cover the topics presented during course.
The Report on the practical exercises (A/B) should be handed in at the
end of the course. Together with the oral presentation, it contributes
another 50 % to the final result. Reports must be handed in immediately
before or after the oral presentation.

Literatuur

All materials will be digitally provided through Canvas.
