Reservoir Evaluation Technology (GEO504)

Petrophysical evaluation and interpretation of geological formations are done to understand the storage capacity, fluid flow and reservoir characteristics required for hydrocarbon reserves estimation and implementation of production strategies. This evaluation is done by running a series of core-based measurements and wireline logging data interpretation that provide information about the petrophysical properties of rocks in subsurface layers. Practical projects from different fields/wells of Norway are given and students are introduced to industry relevant software for a full understanding of dealing with real data on different occasions. The principles behind petrophysical evaluation of rocks are relevant to oil and gas exploration, carbon geo-sequestration and geothermal reservoir characterization.

Language of instruction



Petrophysics attempts to integrate core-based data analysis with the wireline logs data for a complete characterization and evaluation of hydrocarbon reserves in different geological formations. In the first part of the course, students are exposed to Special Core Analysis Laboratory (SCAL) concepts where measurements to obtain reservoirs characteristics (porosity, permeability, saturation, capillary pressure) are discussed. This is followed by the wireline logging section where interpretation of lithology and determination of petrophysical properties are presented on the field scale. Different precautions and corrections are delivered in this section and volumetric reservoir estimation are exercised through a real case study from a Norwegian field.

Learning outcome


  • Interpret core data to derive petrophysical properties of rocks in laboratory.
  • Understand the wireline logging operations, data acquisition and quality control.
  • Interpret wireline logs data for volumetrics reserve estimation and quantification
  • Use appropriate software for interpretation of core, logs and well test data


  • The candidate is able to perform core-based data analysis and wireline log data analysis for hydrocarbon reserve estimation
  • Use software to analyse different logs data for reservoirs characterization

General competence:

  • Students should be able to analyse, and report their strategy for geological reserve estimation
  • Be able to use industrial accepted software to implement their strategies for formation evaluation

Continuous evaluation.You must pass all parts to pass the course. All parts must be assessed in order to receive a grade. If you fail the assessment, you must retake the following year. There are no continuation opportunities on the assessment parts. Students who wish to take these sections again must do so the next time the course has regular instruction.

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
