First EAGE Workshop on Fibre Optic Sensing for Reservoir and Production Monitoring
9-11 March 2020 | Amsterdam, The Netherlands
Workshop Course
Distributed Fibre Optic Sensing
Monday 9 March 2020 (9:00 - 16:30)
Convened by Mahmoud Farhadiroushan (Silixa Ltd)
*This course is included in the workshop registration fee.
Course Description
Distributed optical sensors can provide new ways for monitoring dynamic fluid movements along the wellbore and for acquiring high resolution seismic images deep down in the reservoir. The temperature, strain and acoustic energy can be measured along the entire length of sensing optical fibre. Multiple fibres can be housed within a cable and deployed in different configurations to offer novel methods to acquire data continuously downhole.
This course provides introduction to fibre optics and the basic principles of distributed sensing technology. It also covers key components, cable designs and installation methods for onshore and offshore completions. Case studies focusing on the implementations and applications across the oil and gas industry will be presented in order to gain a better understanding of the practical benefits of distributed fibre optic sensing technology. Advanced system architectures to address future applications, such as subsea wells, will be also highlighted.
Participants' Profile
Anyone interested in gaining a practical knowledge of fibre optic distributed sensing technology and its applications. Attendees do not require any previous experience or knowledge of fibre optics

Mahmoud is a founder and Executive Director of Silixa. He has many years of experience in design, development and commercialisation of optical fibre sensors. In 1998 he co-founded Sensornet that was later funded by Shell Technology Ventures and then merged with Tendeka in 2009. From 1994 to 1998, he was a Senior Research Fellow at King’s College London managing one of the most successful European collaborative projects. He also initiated a joint industrial project developing optical fibre sensors for upstream oil andgas applications, which led to the creation of Sensor Dynamics and Sensa that was acquired by Schlumberger in 2001.
Mahmoud is the joint winner of two DTI SMART awards, the prestigious Manufacturing Metrology for World-Class Manufacturing Award (Frontier Science and Measurement) in 2000 and the British Telecom Innovation Award in 2001. Under his leadership, Silixa has received Institute of Physics Innovation Award 2015 in recognition of achieving commercial success built on physics.
