Pressure Transient Analysis

Reservoir Descriptions and Dynamics

Course Description

Pressure transient data may be acquired from wells during exploration, appraisal and production.  Each data set provides important dynamic information that facilitates the decision making process at the various phases of reservoir development.

The course will summarize the fundamentals of pressure transient analysis and discuss some of the recent advances including deconvolution. Emphasis will be placed on the value of information. It will combine explanations of theory (including course notes), worked examples (using Excel) and presentation of real case examples from both oil and gas reservoirs.


  • Well Performance and Steady State Flow
  • Diffusivity and Transient Flow
  • Flow Regimes: Near Well, Reservoir and Boundaries
  • Non-linearities: Gas and Unconventionals
  • Calibration of full field reservoir models

Tim Whittle Tim Whittle is currently a visiting professor at Politecnico Torino, Italy and Imperial College, UK. He joined BG Group in 2007 and, until its transition to Shell, was the chief reservoir engineering advisor and group technical authority for pressure transient analysis. He has 39 years' experience in the industry.

Starting as a field engineer with Flopetrol Schlumberger, he gained practical experience in well testing operations and then moved to an R&D role where he was instrumental in developing the derivative analysis method with Dominique Bourdet. In 1985 he joined Scientific Software-Intercomp as a reservoir engineer focusing on numerical simulation. In 1990 he spent several years with Norsk Hydro as a well test analysis specialist and then became responsible for the development of SSI’s Interpret well test analysis software product. 

Whittle holds a bachelor's in engineering science from Cambridge University, has written several technical papers on well test analysis and given many industry courses on the subject around the wold. He was an SPE Distinguished Lecturer in 2010-11.
