... Vertical seismic profiling (VSP) survey differentiates itself from surface seismic survey by deploying receivers inside the borehole, while the sources are excited on the surface. Due to this distinctive acquisition geometry, special attentions should be paid in processing and imaging the VSP...

... images range from millimeters to hundreds of meters, which is then compared with vertical seismic profile (VSP) data at tens of meters of scale and sonic velocities at less than 0.5 m scale. Sonic imaging techniques from both monopole and dipole sources can be further used to extend the volume...

... Abstract Distributed acoustic sensing (DAS) is a rapidly evolving fiber optic technology for monitoring cement curing, perforation performance, stimulation efficiency, and production flow and, more recently, for performing vertical seismic profiling (VSP). VSP data can be acquired and processed...

...Introduction In the oil industry, attempts are made at all stages of oil exploration to minimize economic costs associated with uncertain drilling risks. One of those attempts, is the Vertical-Seismic-Profile (VSP) inversion which of all well log measurements, is the only measurement have look...

... ABSTRACT Distributed acoustic sensing (DAS) faces many challenges to become a stand-alone acquisition system. The recorded signal-to-noise ratio (S/N) is sometimes too small to identify clear seismic first arrivals in vertical seismic profile (VSP) surveys. Coupling of sensors with the medium...

... techniques. However, applying standard common reflection point processing to earthquake sources is inappropriate because the sources are not at the surface. An earthquake occurring several kilometers beneath a surface receiver array has a more natural analog: an offset reverse vertical seismic profiling...
