Course Goal
Providing information to students on the general principles and applications of the borehole geophysics. Students are brightened about the main principles of log interpretation and applications.
Course Content
The course consists of two parts Part A focuses on the physical principles of different borehole measurements and the petrophysical uses and geological interpretation of the logs. Part B comprises practical examination in well log data acquisition followed by data processing and interpretation. The training of basic log interpretation techniques is supported by examples and the use of standard log interpretation software. Contents of part A: Basics of data acquisition, data processing and quality control. Wireline and LWD techniques. Principles of conventional measurements (gamma, neutron, density, sonic, resistivity). Principles of special measurements (Image logs, NMR). Log interpretation techniques: e.g. rock identification, sequence analysis, fluid and hydrocarbon identification, cross-plot and overlay techniques. Basics of core-log integration; link to laboratory petrophysics and geochemistry. Basics of petrophysical applications: e.g. porosity, saturation, permeability. Contents of part B: Practice in slim hole logging. On-site training: unit mobilization, tool calibration and data acquisition. Data editing and quality control: borehole corrections, depth matching, splicing. Integration of logs with information from core or cuttings from the measured well. Interpretation of the recorded data and preparing a report.
Course Precondition
To have taken General Geology and Tectonics courses.
Resources
Lecture Note: Well Logs.
Notes
Current studies on the subject on the web.
