Subsurface Interpretation and Modelling (GEO505)
The aim of this course is to provide advanced skills to analyse and to interpret subsurface geophysical and geological data, to construct three-dimensional structural models, and to use outcrop analogues to understand the controls of tectonics in sedimentation for making up reservoirs at the macro scale (meter to kilometre). The students will interpret worldwide case studies using leading edge software widely popular in the energy sector. The skills learned in this course have great applicability in the energy industry (e.g. hydrocarbon exploration and production, geothermal), CO2 sequestration, geohazards and other field areas.
The course is divided in three parts: 1) an interpretation project, including detailed subsurface mapping, which may be part of an international competition; 2) construction of three - dimensional structural models, and related uncertainty; and 3) a field mapping/modelling excursion as analogue for the subsurface.

- To build 3D structural models.
- To map regional geological structures.
- To use leading edge interpretation/modelling software.
- To evaluate uncertainty and include in the interpretation/geomodelling process.
