Well Test Interpretation in Practice
Format and Duration:
4 days
This course provides participants with the advanced skills and understanding required to analyse complex pressure transient tests. The methodology followed has become the industry standard, systematic way of interpreting well tests in homogeneous and heterogeneous reservoirs, including fissured and multilayered systems. Recommendations for designing tests in such formations are also addressed for oil, gas and multi-phase flow wells.
Feedback
Excellent course for practicing engineers. I've gained a lot of theoretical and more importantly practical aspects of well testing.
Schedule
Duration and Training Method
This is a four day classroom based course, with problem solving sessions for practical experience and immediate application.
Course Overview
Learning Outcomes
Participats will learn to:
- Evaluate, select and apply the appropriate diagnostic methods for analysing presssure transient data.
- Apply the appropriate well and reservoir models for analysis.
- Assemble the well and reservoir data needed to design a well test.
- Formulate and recommend well test objectives.
- Design a well test to achieve the desired objectives.
- Perform quality controls on test data.

- Interpretation versus reservoir models
- Identification and verification of interpretation models
Interpretation methods:
- Straight line analysis
- Log-log analysis
- Pressure derivative analysis
- Deconvolution
Interpretation models:

Background
Professor Alain C. Gringarten holds the Chair of Petroleum Engineering in the Department of Earth Science and Engineering at Imperial College in London, where he is also director of the Centre for Petroleum Studies. Prior to joining Imperial College in 1997, he spent fourteen years with Scientific Software-Intercomp; five years with Schlumberger; and five years with the Bureau de Recherches Géologiques et Minières in Orléans, France, in various senior technical and management positions.
Dr. Gringarten is a recognized expert in well test analysis and received the Society of Petroleum Engineers (SPE) Formation Evaluation award for 2001, the 2003 SPE John Franklin Carll award, the 2005 SPE Cedric K. Ferguson certificate for the best technical paper published in 2004, and the North Sea SPE Regional Service Award for 2009. He was a SPE Distinguished Lecturer for 2003-2004. He has published over eighty technical papers and was responsible for many advances in well test interpretation. He was also an early pioneer of multidisciplinary studies, both in industry and in academia. His research interests include gas condensate and volatile oil reservoirs, fissured fluid-bearing formations, hydraulically fractured wells, horizontal and multilateral wells, high and low enthalpy geothermal energy, Hot Dry Rocks, and radioactive waste disposal.
Prof. Gringarten has taught numerous well test interpretation industry courses around the world and has been involved in many consulting projects through his company Well Analysis Limited. A member of the Society of Petroleum Engineers (SPE) since 1969, he was elected a Distinguished Member in 2002 and an Honorary Member in 2009. He has chaired or helped organize many SPE Advanced Technology Workshops, Forums and Conferences. He is currently a member of the SPE International committees on R&D; Information and Management; Carll-Uren-Lester Awards; and is the 2011 chairman of the SPE Talent Council.
