Well logging 1300-OGFOP-GGG
The course includes the issues associated with the application of well logging in the interpretation of the lithology of drilled sedimentary rocks and in the investigation of their textural properties.
The classes are divided into a theoretical part, during which the theoretical background of selected well logging methods is discussed, and a practical part, during which students use dedicated software to perform simple geological interpretations and calculations of basic reservoir parameters of rocks.
The theoretical part (lectures) includes the discussion of the following logging methods: natural gamma ray logging (GR), gamma-gamma density logging (RHOB), neutron logging (NPHI), acoustic interval transit time logging (DT), resistivity logging, and spontaneous potential logging (SP). For each of these logging methods, the geological objectives, limitations, and methods of graphical data presentation are discussed.
During the practical part, students become familiar with digital logging data and independently prepare lithological interpretations for selected well profiles. During the practical classes, students learn the basic methods for calculating shale volume and effective porosity of sedimentary rocks. In the final class, a group project is carried out involving lithostratigraphic interpretation of the studied profile and identification of formations with the best reservoir properties based on geophysical logging data.
Well logging is one of the fundamental geological subjects which provides the basis for further education, particularly in the fields of sedimentary basin analysis and petroleum geology.

Assessment criteria
The course is conducted both in lecture rooms and in a computer laboratory.
The practical classes are assessed on the base of:
• preparation of electronic attachments documenting the students’ individual work;
• preparation of electronic attachments documenting the students’ group work;
• the grade obtained from the final test.
The final test is written and consists of open-ended questions as well as schemes and graphs requiring interpretation. It covers topics presented during both the theoretical and practical parts of the course. Admission to the final test requires the completion and passing of all reports.
