Learning outcome

This course is based on the application of concepts that have been provided in previous courses in the area of petroleum geology, structural geology, stratigraphy and geophysics through the use of specialized interpretation software.


  • Fundamental background on how to build a subsurface 3D model
  • Knowledge on basic well correlation and time intervals in sedimentary basins
  • Knowledge on the geologcail significance of subsurface mapping and importance for hydrocarbon exploration and production


  • Be able to built a subsurface earth model using leading edge software tools.
  • Be able to integrate geological and geophysical data in order to build a subsurface model.
  • Be able to to correlate well and seismic data using time/depth relationships and syntethic seismograms.
  • Be able to make oral presentations in order to provide an overview of the geological model and provide guidelines for exploration and production.

General competence:

  • Have fundamental skills on integration of different types of data in petroleum geology and petroleum engineering, and provide the understanding for other engineering activities such as drilling and reservoir.
  • To communicate and make technical presentations in the area of expertise.
  • Introduction to the subsurface interpretation software
  • Introduction to the subsurface geology of the Norwegian Continental Shelf
  • Seismic and well data interpretation
  • Synthetic seismogram
  • Basic mapping of reservoirs
  • Generation of deliverables for report and presentation
  • Techniques for fault interpretation
  • Depth conversion
  • Reservoir model
  • Note: A two-day intensive software course (e.g. Petrel) is offered at the beginning of the semester. Participation in the two-day course is highly recommended as all following activties during the semster will be done using the software.
Required prerequisite knowledge
GEO100 Earth, energy and climate, GEO210 Structural Geology, PET110 Geophysics and Well Logging
Recommended prerequisites
It is recommneded to have basic knowledge in general and petroleum geology, sedimentology and stratigraphy, structural geology and geophysics

Folder evaluation, oral presentation and written exam

Form of assessment Weight Duration Marks Aid
Folder evaluation 2/5 A - F All.
Oral presentation 2/5 30 Minutes A - F
Written exam 1/5 2 Hours A - F All.

The course has a continuous assessment consisting of one oral presentation, one portfolio and one final exam. All parts must be passed in order to pass the course.The Portfolio contains Laboratory reports. The grade of the Portfolio is not given until all the reports have been assessed and the folder as a Whole graded. For the Portfolio or oral presentation, there are no resit possibilities.
