Course content

The course focuses on selected topics from well data acquisition methods and the interpretation of these data, extending the concepts taught in the basic course in petrophysics. There will be project exercises connected to the Gullfaks database. Integration with other data types. Basic petrophysical relations and points of view. Radiometric methods in open and cased boreholes: Spectrometry - natural and induced, neutron lifetime logging (saturation behind cases), mud logging. Nuclear magnetic resonance, NMR. Properties of clay and shale. Water saturation models in shaly formations. Uses of core data. Pressure measurements. Acoustic and mechanical rock properties. Properties of carbonates.

Learning outcome

Ingress:
The course builds on course TPG4175 Petrophysics Basic Course, and more advanced and different measurements and the interpretation from these measurements. Skilled people from industry teaches parts of the course.

Knowledge:
Surface logging - also called mudlogging, logging for rock properties behind casing, radioactive spectrometry, neutron life time measurements for saturation behind casing, shale and clay properties, water saturation in shaly rocks. Acoustic and electrical imaging in boreholes, magnetic resonance logging, induction logging, pressure measurements, coring, geomechanics, fluid typing.

Skills:
The students shall understand the thought methods and interprete the data from these.

General competence:
During group work the students learn to cooperate and to take responsibility for their part of the assignments given.
By working with real data from the field, they learn to understand that real data can be uncertain and that one has to use common sense and understanding in order to find good answers to the interpretation problems.

Learning methods and activities

Lectures and group work. PBL may be used. Compulsory exercises. Tests during the semester may each count up to 30% of the final grade. The exam can be changed from written to oral at the postponed exams - continuation exam. At continuation and retake of the exam the main exam counts 100%. Lectures are given in English and the examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
