Description
This course will provide a comprehensive methodology for production data analysis that combines the use of several powerful rate transient analysis tools and techniques. Students will use typecurves, flowing material balance, analytical model and hybrid numerical model analyses during this 2-day class.
Participants will learn how to:
-
Critically assess data quality and perform qualitative diagnostics on well production data
-
Identify reservoir flow regimes from rate/pressure response
-
Estimate reserves, OGIP/OOIP and drainage area
-
Determine reservoir parameters such as permeability and skin
-
Perform production data history matching, using both analytical and hybrid numerical models
-
Assess well performance and identify optimization candidates
-
Examine the practical aspects of rate transient analysis using examples
Note: This is an introductory software course designed to familiarize students with the features and functionality within the software. While some theory will be presented, detailed theory and play-specific workflows are beyond the scope of this class.
