This 1-hour training explains the well test theory, assumptions and tools. This is put into practice with a gas condensate appraisal well and some techniques are also presented to validate and analyze the data using a well test software. This session is also the foundation for the next training on Deconvolution.

Training Objectives

What are the training objectives ? 
The main objectives are to:
  • Give an understanding of the well test theory, its limitations and assumptions,
  • Be able to read a derivative plot and recognize a particular well and reservoir response,
  • Get an understanding of the well testing tools, the how and why (why do we derive in a certain way ? why do we use the superposition time ?, etc…)
  • Have some basics on data validation and interpretation with a case study.
This training is also the foundation for the next training video on the latest tool: Deconvolution. 

Agenda

What will be covered ? 
This 1-hour training shows the theory behind well test analysis and a case study on a vertical gas condensate  appraisal well.
The well test theory is explained for a producing well in a new reservoir and the flow behaviour is described for different types of wells. This theory is then extended to any shut-in period. A minimum number of equations are given to avoid complicating the issues in well test analysis.
The 2nd part of the video shows a “live” exercise using a well test software with data validation and analysis for an appraisal well.
The areas covered are:
  • Derivation of the fluid flow equation
  • Definition of the radial flow regime
  • The derivative golden statements
  • Other typical flow regimes
  • Possible well and reservoir configurations
  • 2 examples
  • Application of the well test theory to any PBU and definition of the well testing tools.
  • Case Study with software: well test analysis of an appraisal well
