This 1-day course provides a comprehensive methodology for the diagnosis, analysis, and forecasting of well production data in unconventional resources. An extensive evaluation of the diagnostic tools for assessing data viability, checking data correlation along with flow regime identification is presented. The principal focus of the course is to diagnose the characteristic flow regimes associated with well production and to apply methodologies to estimate performance parameters and forecast production. These methodologies include simple analytical tools, decline curves, and more complex techniques such as non-linear numerical simulation. Examples from tight gas sands, gas shales, and liquids-rich shale systems will illustrate the theoretical considerations and practical aspects of the analysis and forecast techniques. A course notebook will be provided with copies of PowerPoint slides and a list of reference materials.

Learning Outcomes:

• Learn how to collect, analyze, and interpret critical data for well performance analysis
• Identify well performance characteristics and flow regimes using diagnostic plots
• Estimate key reservoir and completion parameters using model-based production analysis
• Forecast future performance of single/multiple well(s) for various production/completion and field development scenarios
• Establish the optimal workflow to help quantify well performance uncertainty and non-uniqueness

This course is suitable for technologists, engineers, and engineering managers involved in the evaluation of well performance (time-rate-pressure) data for optimizing production, understanding completion efficiency, and estimating reserves and ultimate recoveries.

Production analysis and forecasting in unconventional resources are challenging tasks due to the high degree of uncertainty and non-uniqueness associated with evaluating well completion and understanding reservoir properties. This course provides guidelines on the interpretation of data behavior and a consistent approach to analyzing and forecasting production in unconventional resources.
