Distributed Acoustic Sensing (DAS) uses fiber optic cables to provide distributed strain sensing. It is based on the Rayleigh scattering principle, which dictates that for light frequencies below the resonance frequency of the scattering medium, the amount of scattering is inversely proportional to the fourth power of the wavelength. For…
Oil and gas operations are commonly found in remote locations far from company headquarters. Now, it's possible to monitor pump operations, collate and analyze seismic data, and track employees around the world from almost anywhere. Whether employees are in the office or in the field, the internet and related applications enable a greater multidirectional flow of information – and control – than ever before.
