... this, we installed and tested a buried experimental multi-component fiber sensor called the “Pretzel” at the Carbon Management Canada Newell County Facility in 2018, consisting of two 10x10 m horizontal squares of fiber. The 10 m sides of the Pretzel are longer than the 7 m gauge length that we typically...

... Raw land seismic data acquired with point sensors has lower signal-to-noise ratio (SNR) than that acquired using geophone arrays due to noise attenuation in the array. However, the benefits of trace density and unaliased wavefield sampling for denoise and image resolution, combined with the ease...

Synthetic examples demonstrate the reliability of this method when applied on seismic data with different signal-to-noise ratios. We apply the method on about seven-month-long seismic data recorded by seismic sensors deployed...

... Seismic field data suffer from Low Resolution (LR) image quality. This is due to the limited number of sensors used in a given seismic survey, as well as physical and technological limitations of the sensors. To obtain high-resolution (HR) images, either higher density acquisitions are carried...
