Course Content

Who Should Attend

Petroleum engineers, managers and geoscientists who would like to learn RTA in a practical and hands-on way.

Why Attend

This course outlines limitations in traditional RTA analysis, and goes through three new technologies that has been introduced the past few years to help enhance our understanding of tight unconventionals, namely (1) Numerical RTA (2) multiphase flowing material balance (FMB) and (3) Fractional RTA.

Course Content

Two common goals of Rate Transient Analysis (RTA) are the quantification of early time well performance using the Linear Flow Parameter (LFP), as well as the contacted pore volume being drained (e.g. OOIP and OGIP). These two parameters are essential for understanding the effects of completions, geology, and depletion which then advises different strategies for optimizing the economics of future development.

We’ll cover the following topics in the course:

  • RTA inputs
  • Production data
  • PVT
  • Bottomhole pressures
  • RTA What’s New?
  • Multiphase Flowing Material Balance (FMB)
  • Analytical & Numerical RTA
  • Classical vs. Fractional RTA
  • Numerical reservoir simulation/modeling
  • Example Cases & Exercises


  • Fee: Member $750 / Nonmember $950 / Student $300
  • Limit: 40 Attendees
  • Includes: One-day course with lecture, access to SPE's Learning Management System, class exercises and discussion, morning and afternoon refreshments and lunch. .08 CEUs (Continuing Education Units) are awarded for this one-day course.
