Applied Unconventional Reservoir Analysis (BACRES04LIC1)

  • 2 daysLicense period: 1 Month Course Fee: 295 EUR


This is a short, intense course covering an introduction and definition of unconventional reservoir analysis. You will see the characteristics of unconventional reservoirs, including a shale overview, and typical rock and typical fluid properties. We will look at the decline curve models and production and reserves predictions. You will practice the application of the theory using Citrine and Topaze software from KAPPA Engineering. IChemE accredited course (14 CPD hours).

Designed for you, if you are...

. . . anyone desiring to understand the new techniques involved in unconventional reservoir analysis and how these are applied in commercial software.

The benefits from attending

  • List the main types and characteristics of unconventional reservoirs and explain how they are defined
  • Identify key reservoir rock and fluid properties for unconventional reservoirs and explain how this influences the fluid flow regimes
  • Compare and contrast the different methods used for decline curve analysis in unconventional reservoirs. Explain how these differ from traditional methods
  • Categorise the production decline characteristics for multi-fractured horizontal wells in shale reservoirs. Explain how to estimate remaining reserves for each well and field
  • Describe the recommended workflow for unconventional reservoir analysis. Illustrate with practical applications for field performance matching and prediction (Citrine, Topaze)
