Pioneering Optical Fibre Sensing Distributed Pressure Sensing Case Study December 2016 1 © Smart Fibres Ltd Project Objective: • To develop and deploy a low-cost distributed pressure and temperature measurement system as a novel new technology to manage fractured carbonate oil rim reservoirs • To replace the conventional method of reservoir management via repeated, periodic gradio surveys • Project Sponsors: Shell, NL PDO, Oman 2 © Smart Fibres Ltd The Challenge: Fractured Carbonate Reservoirs Typical Situation Faced by Operators • Very large reservoirs, multiple wells • Thin oil rim with gas cap above and aquifer below • Oil rim must align with the perforations in producing wells But • Oil is very mobile in carbonates – fractured / high permeability • Lea
