How to measure strain using fiber Bragg gratings

How to measure strain using fiber Bragg gratings

This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed. The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is difficult to perform using widespread methods and devices. A fiber Bragg grating is a small length of optical fiber that comprises a pattern of many reflection points that creates a reflection of particular wavelengths of incident light.

Fiber Optic Sensing Pressure Test

Fiber Optic Sensing Pressure Test

One of the key steps in the data preparation was to align the downhole sensor data spatially and temporally. As summarized in Table 1, DAS, DTS, and the pressure gauges had sampling times of 10 s, 12 s, and 1 s, respectively. The data analyzed in this study was obtained from two-phase (nitrogen gas and water) flow experiments conducted in a 5163-ft deep test-well located in the Petroleum Engineering Research and Technology Transfer (PERTT) lab facility at LSU (Fig.
