ㅇ 주요 교육내용
- General review of and integration of various data types(well and seismic, and other data types)
- Well log analysis, including log types, correlation of well logs, and extraction of relevant subsurface and reservoir data
Brief review of key log types, including gamma ray, spontaneous potential, resistivity, porosity logs, and others.
Azimuthal(image) logs : wireline (FMI-type and ultrasonic) and LWD(e.g., gamma ray, density, caliper, resistivity, etc.)
Log correlation
Data extraction
Reservoir characterization
- Seismic analysis, including 3D, time-lapse, and attribute analysis
Brief review of principles of reflection seismology
2D versus 3D(and time-lapse) interpretation/mapping concepts
Attribute analysis and AVO
- Tying Seismic and Well Log Data
Data conditioning of both seismic and well log data
Synthetic seismograms
Seismic inversion techniques
- Pitfalls and Differences between Datasets
Resolution variations(lateral and vertical)
Time to depth conversion(both seismic and well log data are acquired in time and must be converted to depth)
Phase wandering on seismic data(pre-stack and post-stack domains) and issues with tie to well data
Elastic properties, including velocity, vary with frequency
(seismic and well log data are acquired using different frequencies)
