Log Quality Control Course

Course Details

This is a course designed for geologists, geophysicists, petroleum engineers and other industry professionals who work with electric logs. The course will teach techniques, procedures and best practices for log quality control including open and cased hole logs and advanced tools like well seismic and magnetic resonance. The participants will understand the most common issues at well-site and the corrective actions to fix them. This course can be taken in conjunction with the basic and advanced log analysis courses.

Geologists, Geophysicists, Petrophysicists, Petroleum Engineers and other professionals who are interested on log quality control and data validation. This course is especially useful for well-site witness and log acquisition supervisors.
