... Surface seismic on land demands more significant trace density with finer sampling to address imaging and near surface challenges. It becomes challenging to meet these requirements with conventional point sensors. Distributed Acoustic Sensing (DAS) offers a potentially more attractive...

... array of three-component sensors, focused vector migration resolves directional ambiguities responsible for artifacts, normally attributed to spatial aliasing. This approach also allows using the high-quality estimates of the signatures of the elastic waves generated by a microseismic event to image...

... modulated communication protocol allows us to communicate data efficiently and send power over a single conductor wireline. This modular geophysical logger can easily be reconfigured to be used with multiple sensors. The first use case of this logger is a Vertical Seismic Profiling tool chain. The novel...

... 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...

... are recorded at two times in hundreds of isolated traffic signals and frequency. 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...

... A novel approach to full waveform inversion (FWI), based on a data driven reduced order model (ROM) of the wave equation operator is introduced. The unknown medium is probed with pulses and the time domain pressure waveform data is recorded on an active array of sensors. The ROM, a projection...

Herein we describe a full microseismic data set with a subset of 30 co-located surface arrays and shallow borehole arrays. The data was processed using...

... Land seismic is evolving towards denser surveys, single sensor recording, and lower frequencies. A number of new nodal systems have been introduced to facilitate this evolution: some use moving coil geophones, while others use new sensors, based on MEMS or piezoelectricity, which record...

... Distributed acoustic sensing (DAS) for microseismic monitoring is increasingly attracting attention from both scientific and industrial communities. It is an alternative approach to traditional point-sensor arrays, which permit sampling only at a limited number of physical locations. Conversely...
