Reflection Seismic for Geologists

2019-2020

Course Objective

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.

Course Content

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.

Teaching Methods

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.
Attendance to all oral lessons is compulsory. 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.

Method of Assessment

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.

Literature

All materials will be digitally provided through Canvas.
