Well Test Analysis in Practice

This course will enable participants to understand the fundamental concepts of well test analysis.  The methodologies described in the course, which have become the standard of the industry, will present the systematic way of interpreting well tests.  Attendees will also participate in problem-solving sessions of the term of the course.

Day 1

Well Test Interpretation Methodology

  • Well Testing as a signal analysis problem
  • Concept of interpretation model
  • Straight-Line and pressure log-log analyses        

On the first day, attendees will be introduced to the main concepts of well test analysis.  Two historic approaches for interpreting well test data will be covered.  Topics covered will include the concept of the interpretation model and straight-line and pressure log-log analyses.             

Day 2

Well Test Interpretation Methods

  • Derivative analysis
  • Deconvolution
  • The use of simulators in well test analysis     

Day two will build on what was learned the day before.  Participants will continue to learn about the interpretation techniques.  Examples of wells with wellbore storage and skin effect in an infinite reservoir with homogeneous behavior will be presented.              

Day 3

Well Test Interpretation Models

  • Hydraulically fractured wells
  • Partial penetration, horizontal wells, and composite behavior
  • Double porosity behavior

Day three will cover hydraulically fractured wells, partial penetration, horizontal wells, and composite behavior.  A presentation of near-wellbore and reservoir interpretation models with examples will be covered.  Double porosity behavior will also be discussed.              

Day 4

Well Test Interpretation Models (Cont.)

  • Double permeability behavior
  • Simple boundaries
  • Complex boundaries     

The focus of day four will be the continuation of the presentation of interpretation models with examples.  Specific models that will be covered include double permeability behavior, as well as simple and complex boundaries.

Day 5

Additional Well Test Analysis Topics

  • Gas and multiphase flow
  • Test design
  • Practical well test analysis considerations

On the last day participants will learn about how the methods described for oil in the previous four days can be extended to gas and multiphase flow.  Participants will also learn about test design and practical well test analysis considerations.  Everything that has been taught during the course will be summarized into a set of practical rules. 

Learning activity mix

Reservoir engineers, production engineers, and field personnel involved in the design and interpretation of well tests.

Participants should have knowledge of transient well testing nomenclature.
