Pressure transient analysis (enhanced applied)

General information

Working language:


The training duration:

32 hours

The target audience:

Specialists in the sphere of oil and gas field development and operation, reservoir production improvement.


The office of SIAM MASTER Ltd: 10 a Oktyabrskaya street, Tomsk 634003. The minimum number of trainees for the training is 6.

Carrying out different activities focused on analysis of certain parameters: pressure, temperature, liquid level, production rate etc.) and sampling of reservoir fluid (oil, water, gas and gas condensate) in flowing and shut-in wells and their recording in time / at different times.


  • training is conducted in the form of online training which implies audiovisual delivery (presentation) and active involvement of trainees;
  • discussion of problems and questions;
  • practice in specialized software;
  • solution of difficult problems and questions of those trainees who have already worked in the field of design and interpreting well testing;


  • quality improvement of conducted well testing, together with cost saving on ineffective measurements and testing; improvement of prompt technical monitoring of field development;
  • introduction of new methods of interpretation and conducting well testing together with cost saving on measurements and testing;
  • quality improvement of a priori unsuccessful and complicated testing;
