About

About the course

Course content

Fundamental petrophysical concepts and equations. The most important classical well logging methods: Measurements of resistivity, natural gamma ray, neutron porosity, density, average atomic number parameter, Pe, acoustic parameters, measurements of formation pressure. Discussions of the measurement environment and geometrical conditions in a borehole. Environmental corrections. Nuclear magnetic resonance, NMR. Dielectric properties. Connections between the measured parameters and the rock's porosity, permeability, fluid/gas saturation, lithology (rock types) and clay content. Use of core data. In the exercises emphasis is put on practical interpretation of log data.

Learning outcome

Give an introduction to the most common measurements carried out in boreholes and practical interpretation of these. From log data the students are expected to recognize the most common lithologies, find porosities, saturations (Archie) and fluid types.

Learning methods and activities

Lectures and group work. PBL may be used. Compulsory exercises. Tests during the semester each count up to 30% of the final grade. The exam can be changed from written to oral at the postponed exams (continuation exam). Lectures are given in English.

Compulsory assignments

  • Exercises

Course materials

Compendium, lecture notes, Correction Charts. Articles. Log data from the North Sea.
