Well Test Interpretation

Further your knowledge of well testing

Need an enhanced drill stem test interpretation? Seeking deeper well testing comprehension?

This oil and gas training course will cover the reasons for well testing and the information that can be derived from it. The procedures and principles for analyzing vertical well tests will also be applied to horizontal wells. The course will deal with both oil and gas well test interpretation, drillstem tests, wireline formation and production tests, interference tests, detection of boundaries, estimation of stabilized flow rates from short test, etc.

The practice of well test interpretation will be emphasized over the theory. Data validation and the primary pressure derivative (PPD) will be used to illustrate wellbore dynamics and to extricate these effects from the apparent reservoir response. Throughout the course, the instructor will show that Well Test Interpretation (WTI) involves a lot more than simply Pressure Transient Analysis (PTA).

Topics Covered
  • Introduction: why test, course philosophy, types of tests, fluid types, reservoir types, well test interpretation approaches
  • Basic concepts: simplifying assumptions, drawdown test, typecurves, skin effect, wellbore storage
  • Gas flow considerations: turbulence, pseudo-pressure, pseudo-time
  • Flow regimes – vertical wells: segmented approach, early time (wellbore storage), transient flow (radial), late time (transition)
  • Flow regimes – horizontal wells
  • Useful concepts: radius of investigation, time to stabilization, superposition
  • Drawdown analysis (or injection): procedure, specialized analyses, horizontal wells
  • Buildup analysis: Horner plot, equivalent time, M.D.H. plot, average reservoir pressure, detection of boundaries, other buildup curves, D.S.T., horizontal wells
  • Non-reservoir effects: data validation, wellbore dynamics, primary pressure derivative (PPD)
  • Production forecasting and analysis: transient/stabilized IPR, AOF (sandface/wellhead), production data analysis
  • Test design, complex models, pitfalls, etc.
Instructor

Louis Mattar, B.Sc., M.Sc., P. Eng.
Mr. Mattar, the former president of Fekete Associates Inc., has over 35 years’ experience in reservoir engineering. He is a recognized expert in the field of well test analysis, has authored some 70 publications and is often called upon to act as an Expert Witness. Louis previously worked for Alberta’s Energy Resources Conservation Board (ERCB), where he wrote Gas Well Testing—Theory and Practice (1975). He also taught reservoir engineering at the University of Calgary as an associate professor. In 2002, Louis was selected as an SPE Distinguished Lecturer, and in 2012, Louis received the SPE Distinguished Membership Award.
