“…Fibre-optic interferometric acoustic sensor array has established itself as a potential alternative to the conventional sonar array based on electro-ceramic transducers for underwater or subsea applications [59]. A metal-coated hybrid sensing system based on FBG and Extrinsic Fabry-Perot Interferometer (EFPI) cavity for high-pressure high temperature (HPHT) measurement has been reported for subsea underwater applications wherein the FBG and EFPI are used to measure temperature and pressure, respectively [60].…”

Oil and gas (O&G) explorations moving into deeper zones for enhanced oil and gas recovery are causing serious safety concerns across the world. The sensing of critical multiple parameters like high pressure, high temperature (HPHT), chemicals, etc., are required at longer distances in real-time. Traditional electrical sensors operate less effectively under these extreme environmental conditions and are susceptible to electromagnetic interference (EMI). Hence, there is a growing demand for improved sensors with enhanced measurement capabilities and also sensors that generates reliable data for enhanced oil and gas production. In addition to enhanced oil and gas recovery, the sensing technology should also be capable of monitoring the well bore integrity and safety. The sensing requirements of the O&G industry for improved sensing in deeper zones include increased transmission length, improved spatial coverage and integration of multiple sensors with multimodal sensing capability. This imposes problems like signal attenuation, crosstalks and cross sensitivities. Optical fibre-based sensors are expected to provide superior sensing capabilities compared to electrical sensors. This review paper covers a detailed review of different fibre-optic sensing technologies to identify a feasible sensing solution for the O&G industry.

“…Typically, photonic crystals are periodic optical (micro or nano) structures running axially along the length of the optical fibre, that affects the propagation characteristics of the electromagnetic waves travelling through its core 17 . In our past studies, we have reported modelling and simulation studies for FBG/ PCF-FBG sensors for various oil and gas sensing applications [18][19][20][21][22] . PCFs normally have two modes of operation based on their light guiding techniqueindex guiding and bandgap guiding 23 .…”

“…In the range of 0 -0.45 MPa, with increments of 0.05 MPa, a sensitivity of 6.834 nm/MPa was observed. Furthermore, (Amos, Prabhu, and Nuguna, 2017) proposed a theoretical design of a hybrid FBG/EFPI sensor for temperature and pressure measurements in subsea underwater applications. Simulations showed an increase in temperature sensitivity from 13.95 pm/°C to 23.89 pm/°C.…”

The aim of this study was to investigate the detection of low hydrostatic pressure, serving as the foundation for developing an underwater pressure sensor. This included creating a singlemode, uniformly structured Fiber Bragg Grating (FBG) with a stainless-steel coating. The experiment included loading the sensor with different volumes of fresh water ranging from 0 ml to 6 ml, in increments of 0.25 ml, in the perpendicular vertical direction. This volume range corresponded to hydrostatic pressures ranging from 0 Pa to 40.55 Pa. The experimental results showed a consistent linear relationship between low hydrostatic pressure and Bragg wavelength, implying a sensitivity of 0.8092 pm/Pa, according to theoretical expectations. Subsequently, mathematical simulations were conducted based on the results to predict the sensor performance under various potential seabed temperatures. The simulation results indicated that as the temperature rose, there was a corresponding increase in the reflected wavelength difference by 𝟓. 𝟑𝟕𝟓𝟒 × 𝟏𝟎 −𝟗 nm/Pa for every 1°C increase in seawater temperature.
