PET110_1

Geophysics and Well Logging

This is the study programme for 2019/2020. It is subject to change.


The course provides an introduction to the theory and practice of exploration geophysics including geophysical data acquisition, data processing and interpretation. Methods covered include reflection seismology (emphasized), refraction seismology, gravity and magnetic methods, and electrical and electromagnetic methods. Introduction to petrophysics will be given with focus on well logging. Physical principle, technology and interpretation will be given in order to evaluate the formation/lithology, fluid composition, and fluid flow. Obligatory assignment has to be approved to take the exam.

Learning outcome

After taking this course, the student will:
  • be familiar with the various geophysical methods used in petroleum exploration, development, and production, including seismic, gravity, magnetic, electric and electromagnetic methods. As well as, be able to understand the theory at the foundation of these methods.
  • know how geophysical data is acquired in the field, how it is processed and how it can be analyzed in the context of hydrocarbon exploration and exploitation.
  • understand the basic principles behind petrophysics, well logging, wireline logging, and core measurements, and be able to perform a petrophysical evaluation of lithology, porosity, water saturation, net to gross, permeability and segmentation.

The course provides an introduction to the theory and practice of exploration geophysics including geophysical data acquisition, data processing and interpretation. Methods covered include reflection seismology (emphasized), refraction seismology, gravity and magnetic methods, and electrical (and electromagnetic) methods. Further, the course gives an introduction to formation evaluation, based on logged measurements of electric resistivity, seismic velocity and radioactivity. Coverage will include the principles of measuring these logs, as well as how they are combined with core data to determine lithology, net sand, porosity, water saturation, permeability, and gas/oil volume. Obligatory exercise on laboratory and interpretation of logs has to be approved 21 days before the exam.

Coursework requirements

Laboratorieøvelser
Mandatory lab exercises shall be carried out at the times and with the groups that are specified in Canvas. Absence due to illness or other reasons shall be reported to the responsible lab or course instructor. One can not expect to be able to carry out a lab exercise outside the scheduled period if a new period is not arranged in advance. Without approval of the lab work, you will not be allowed to sit the exam in the course.

Open to

Due to limited capacity at the lab this course will from autumn 2008 only be available for a limited number of students where this course is either compulsory or recommended elective in the correponding study program. (§ 3-7, pkt 5). Students that do not fulfill these requirements have to apply the head of department to get access to this course in accordance with the regulations for application to courses.

Course assessment

Standard UiS routine.

Obligatory exercises must be approved before the student can take the exam.
