The candidates will be introduced to the TDS technique, which is an alternative option to type-curve matching technique, convolution, and regression analysis. The course includes step-by-step procedures to interpret pressure transient tests, such that participants will be able to immediately apply the knowledge and skills gained to their job assignments upon course completion.

By the end of this course delegates will be able to:

• • Learn how to understand the theory, applications, and practical limitations of conventional pressure analysis techniques
  • Acquiring the skill to use the pressure derivative by recognizing unique finger prints of various flow regimes
  • How a post-frac pressure test
  • Accurately predicting amounts and types of porosity
  • Characterize the four different types of NFR
  • Use unique finger prints of the pressure derivative to delineate the fracture system intensity and extent, as well as how to quantify reservoir pore volume
  • learn how fluid properties change with pressure and how they are used to calculate effective permeability to oil, gas, and water
  • Use the TDS technique to analyze pressure buildup tests preceded by variable rate
  • Be able to determine vertical permeability
  • Be familiar with several methods to analyze pressure drawdown and buildup tests in horizontal wells, including pressure-based conventional techniques, and techniques that are strictly based on the pressure derivative

Geologists, Petrophysicists, reservoir engineers, production engineers, laboratory researchers, and gas field operators
