By the end of this course, delegates will be able to:

• • Design well tests and specify equipment requirements
  • Set up and analyze well tests for oil and gas well using traditional and modern well testing analysis techniques
  • Perform QC analysis of pressure data; identify and discard bad data
  • Identify various wellbore and reservoir characteristics and choose the appropriate model for analysis
