Review of Well Injection Tests


The purpose of this two-day course is to offer the most practical applications of the various injection tests conducted in the industry; their applications and how to analyze test data through numerous case studies. Injection tests are conducted for: 1. water disposal and injection wells. 2. Steam injection wells. 3. Subsurface injection/disposal/storage of CO2. 4. Frac design using Mini frac tests or Diagnostic Fracture Injection Test (DFIT).




  • Learn the theory of test analysis and techniques
  • Learn what information is obtained from DFIT
  • Understand the benefits of conducting DFIT
  • Learn step-by-step how to analyze DFIT and the use of commercial software
  • Learn the benefits of test design to ensure conclusive results are obtained.
