Advanced Well Test Interpretation Training Course

Advanced Well Test Interpretation Training Course – 3 days

This course is more advanced than the Practical well test interpretation course and has thus incorporated more reservoir models for application. The aim is to equip attendees with an understanding of the theory and practice of pressure transient analysis using analytical methods and an understanding of the geological and fluid parameters which affect the results of pressure transient analysis.

The course will give you skills to interpret pressure transient analysis data for permeability and the various components of skin as well as evaluating reservoir geometry and connected volume using boundaries and mobility / storativity models. The practical element will give participants experience in analysing real sets of test data.

Who should attend?
The course will be suitable for junior to senior engineers aiming at getting an advanced perspective on well test interpretation and its applications.

Course outline
The specific content of the course can be tailored to meet the needs of the attendees.  This is an outline of the typical course:

  • Overview of the development of well testing practice and theory
  • Introduction to PIE – data loading exercise from a spreadsheet and ASCII file and gauge comparison
  • The principles of Superpositions and the rate history
  • Analysis/diagnostic plots and the manipulation of them: Horner, Superposition and Log Log Derivative plots – straight line analysis with examples
  • Well bore storage and skin – with examples, flow regimes: radial flow, spherical flow, linear flow and bi-linear flow, pseudo steady state – what this means and why
  • Type Curve models and examples
  • Boundary theory and practice with examples using PIE
  • Reservoir pressure and reservoir surveillance with examples
  • Gas well testing with examples
  • Horizontal wells with examples
  • Factors complicating well testing and how this affects the pressure responses
  • Managing anomalous data and analyses
  • Composite reservoirs: linear and radial
  • Multi-well analysis set up and practice in PIE
  • Double porosity with examples
  • Double permeability with examples
  • The principles and application of deconvolution with examples
  • Managing the Inverse problem with what is known: testing hypotheses
