Review of Well Injection Tests

Mr. Saad Ibrahim, P. Eng
(1 day) – July 13, August 3, September 7, 2020

Course Objective:

The purpose of this one-day course is to offer a complete coverage the various injection tests conducted in the industry; their applications and how to analyse test data. 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). Learning outcome:

  1. Understand the theory/fundamentals of well test interpretations, including flow geometry and boundary conditions.
  2. Understand the benefits injectivity/fall-off tests to maximize water injection and select candidate wells for wellbore stimulation
  3. Select perforating intervals for unconventional reservoirs using N2 injectivity/fall-off tests
  4. Why conduct step-rate tests and packer leak-off tests
  5. Learn the benefits of the Hall plot for water disposal/injection wells
  6. Learn the aapplications of Diagnostic Fracture injection Test (DFIT) or Mini Frac and their requirements by the AER
  7. Understand the analysis techniques of DFIT including:
    • Pre-Frac Closure
    • After Closure Analysis (ACA)
    • Numerous case studies from the Duvernay and Haynesville shale gas
  8. Learn how to extract geo-mechanical parameters from DFIT; such as, closure pressure, ISIP, and types of leak-off, which are essential to the frac design.
  9. Illustrate how injection tests are analyzed using commercial software

A detailed course hand-out, which is an excellent reference, will be provided. Hand calculators are required for this class.
