Why Choose this Training Course?

Why Choose this Training Course? 

Most types of logs are used to characterize the reservoir behavior prior to install well completion; while several logging tools are available to provide information during production operations and beyond. This PetroKnowledge training course will discuss the various types of cased hole logging and how they can often be used to provide critical information to define production problems and diagnose remedial actions.

Cased hole logging tools are used to efficiently and accurately evaluate the well’s performance. They diagnose and verify potential issues in reservoir performance. Real-time, depth-correlated production data, including flow rates, pressures, gas/oil/water ratios and completion integrity status

Using these key production parameters, it is possible to evaluate production operations and diagnose potential problems such as water or gas breakthrough, crossflow, tubing leaks and this in turn will reduces downtime. 

This PetroKnowledge training course will highlight:

  • Identify what cased hole Logging is and categorize commonly used
  • Distinguish cased hole logging tools including its purpose, benefits, and deliverables
  • Identify the features and benefits of using Cased hole logging technology
