Intended Audience
Well completion and production engineers, and managers and geologists, working in the area of shale gas.

Description
This course will acquaint the participants with recent learnings in regard to well completions, fracturing, and production in shale gas reservoirs. Field data and interpretations will be emphasized in an interactive format. Attendees will receive an overview of shale gas technologies, including muti-stage fracturing in horizontal wells, a summary of field data from different shale gas plays, engineering interpretations of field data, and skills for engineering analysis and field deployment of well completions.
Topics Covered
Candidate selection criteria and examples of commercial production
