Subsurface Interpretation and Modelling (GEO505)
This course provides skills to analyse and interpret subsurface geophysical and geological data, to construct three-dimensional structural models, and to use outcrop analogues to understand tectonic controls in sedimentation for reservoirs at the macro scale (meter to kilometre). Students will interpret worldwide case studies using leading-edge software used in the energy sector. The skills learned in this course have great applicability in the energy industry for hydrocarbon exploration and production, geothermal resources, energy transition, CO2 sequestration, and other field areas.
The course is divided into three parts: 1) an interpretation project with detailed subsurface mapping; 2) construction of three-dimensional structural models and related uncertainty; and 3) a field excursion to a subsurface analogue for field mapping and computer modelling.

Exam
Oral exams and report
| Form of assessment | Weight | Duration | Marks | Aid |
|---|---|---|---|---|
| Oral exam 1 | 35/100 | 15 Minutes | Letter grades | All |
| Oral exam 2 | 35/100 | 15 Minutes | Letter grades | All |
| Report | 30/100 | Letter grades | All |
A field excursion is part of the course. Students who are not able to attend the field excursion will get an alternative assignment with a similar complexity level and equivalent time-demanding assignment based on the excursion. All assessment parts must be passed to obtain a final grade in the course. If a student wants to improve his/her grade, he/she can retake the course again the next time the course is offered. There are no re-sit opportunities for this course.
