Transient Analysis of Oil and Gas Well Tests

Introduction:

The Transient Oil and Gas Well Test Analysis course provides an in-depth exploration of well testing objectives, focusing specifically on transient analysis for oil and gas wells. Participants will learn classical drawdown and buildup analysis methods, as well as advanced gas well testing techniques, including Inflow Performance Relationships (IPR), Absolute Open Flow (AOF) analysis, and well test validation.

The course begins with an introduction to the fundamental principles of oil and gas well testing, covering methodologies for conducting these tests. Attendees will gain essential knowledge of reservoir rock and fluid properties necessary for effective well analysis, complemented by crucial equations. Practical considerations, such as sampling techniques and the use of specialized testing tools in transient conditions, will also be covered.
