The temperature sensitivity of the sensing fiber also affects the temperature measurement performance63,117. The temperature sensitivity gradually weakens with an increment of the effective sensing distance. Besides, the thermal insulation material of the optical cable also restrains the temperature sensitivi...
The potential for subsea downhole optical fibre sensing to optimize hydrocarbon production and hence contribute to enhanced oil recovery is described. The components of susbea downhole optical sensing systems are reviewed and the perform... D Mcstay,G Shiach,S Mcavoy - Journal of Physics Conference...
