Shale Gas Overview–Characterisation to Development

Reservoir Description and Dynamics Management and Information Production and Operations


Recently shale gas reservoirs are becoming increasingly important contributors to the world’s energy production. The purpose of this course is to provide practical insights and tools that can be used to effectively characterize and develop shale gas reservoirs. We will focus on the fundamental understanding of flow at the pore-scale, review what controls productivity, and discuss the various techniques used to determine reservoir parameters and performance. We will review completion/stimulation practices and effects on production. Finally, use of various methodologies from simple decline curve relations to more advanced numerical simulation models will be demonstrated to analyze, model, and forecast well performance.  A course notebook with Powerpoint slides and supplemental materials will be provided.

Learning Objectives:

  • Learn how to collect, analyze, and interpret critical data from multiple disciplines.
  • Understand the controls on gas-in-place and productivity.
  • Evaluate drilling and completion practices and identify how drilling/completion play key roles in productivity.
  • Apply various methodologies to analyze, model, and forecast production and establish workflows to obtain a systematic analysis and forecasting procedure.

Course Length

1 Day

Who Should Attend

Geoscientists, engineers, and managers who want to understand the key characteristics of shale gas reservoirs, what controls their productivity, how to evaluate drilling and completion practices, and how to analyze, model, and forecast well performance.


Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and or/ certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDH). Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training cours
