Training Partner Programme (online): Production and Reservoir Monitoring with Distributed Fiber Optic Sensing, Chemical Tracer, and Production Logging Techniques

Facilitator: Ehsan Nikjoo, Global Product Line Specialist at Weatherford

Course Overview

This course offers an overview of some of the main production and reservoir monitoring techniques and will present the value of each method with real field cases. By the end of the course, participants will develop knowledge about the fundamentals, applications, and advantages and disadvantages of each method, enabling them to make an informed decision about the most suitable monitoring approach for their application.
