Level

  • Foundation
  • This course provides a comprehensive knowledge of cased-hole logging techniques and production log interpretation, along with the industry’s best practices and procedures.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • acquire an insight into well cementation control, corrosion,
  • determine the characteristics of formations behind the casing and reservoir saturation,
  • carry out a quick interpretation of production logs.
