ECTS credit allocation (and other scores):	(not available) Basic information on ECTS credits allocation principles: the annual hourly workload of the student’s work required to achieve the expected learning outcomes for a given stage is 1500-1800h, corresponding to 60 ECTS; the student’s weekly hourly workload is 45 h; 1 ECTS point corresponds to 25-30 hours of student work needed to achieve the assumed learning outcomes; weekly student workload necessary to achieve the assumed learning outcomes allows to obtain 1.5 ECTS; work required to pass the course, which has been assigned 3 ECTS, constitutes 10% of the semester student load. view allocation of credits
Language:	Polish
Type of course:	obligatory courses
Prerequisites (description):	Student before learning of Well logging should attend in courses of Basic Geology (both lectures and exercises), Structural Geology and Introduction to Geophysics.
Short description:	The course includes the issues associated with application of well logging in the structural and sedimentary basin analysis. It allows acquiring the theoretical and practical skills to the interpretations of selected radiometric, electrometric and sonic logging, normally conducted during the drilling of boreholes in the hydrocarbon reservoir exploration. It provides the basis to the further course of education, especially in Sedimentary Basin Analysis and Reservoir Geology.
Full description:	The course includes the issues associated with application of well logging in the structural and sedimentary basin analysis. It presents the geophysical and petrophysical properties of rocks and their record on well logs. It shows in details the selected types of geophysical analyses conducted in boreholes with taking into account the comprehensive classification, based on the physical and geological criteria: gamma ray logging, density logging, neutron logging, sonic (acoustic) logging, spontaneous potential logging and resistivity logging. In each types of well logging are analyzed processing and interpretation of geophysical data and also methods of graphical presentation of results. Particular emphasis is placed on the geological objectives of the measurements i.e.: determination of shale volume, detection of clay minerals type, radioactivity of rocks and minerals, determination of lithology and lithofacies, identification of porosity and permeability of reservoir rocks, recognition of fault zones and folds, determination of fracture levels and detection of rocks with increased resistivity. Well logging is one of the basic geological subjects and provides the basis to further course of education, especially in Sedimentary Basin Analysis and Reservoir Geology.

Learning outcomes:	After the course, both lectures and exercises, student correctly analyses and interprets record of various well logging. Using geophysical data student is able to interpret and correlate selected structural and sedimentological elements. After course student aquaires the basis to further education of Sedimentary Basin Analysis, Methods of explorations and prospection of reservoirs and Reservoir Geology.
Assessment methods and assessment criteria:	The course is consisted of lectures (after 2 hours) and exercises (after 2 hours). The exercises are classified on the basis of presence and evaluation of individual attachments making on each exercises. Two excused absences are allowed in the semester. The absence does not release the student from making the individual attachment. In addition, at the end of the course takes place written test. It covers all the issues presented on the lectures and exercises. It consists of a test, calculations, short open-ended questions and drawings/logs to interpretation or explanations. The condition of admission to the written test is passing all individual attachments. Exercises: presence and evaluation of attachments Lectures: written test on the penultimate lectures in the semester. The correction written test is planned on the last lecture in the semester.
Practical placement:	none
