Quality Control and Validation in Geophysical Well Log Digitization
Geophysical well logs are among the most valuable subsurface datasets available to geoscientists. For decades, oil and gas operators, mining companies, hydrogeologists, and environmental engineers relied on paper well logs to record downhole measurements such as resistivity, gamma ray, spontaneous potential (SP), density, and sonic velocity. These logs formed the backbone of reservoir characterization, stratigraphic…
