... 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...

... ABSTRACT In a DAS time-lapse VSP survey, P-wave arrival time differences have been observed before and after hydraulic fracturing for each of 78 stages along a horizontal well. The time delays can shed light on fracture geometry and surrounding rock properties, but the mechanism causing...

... (VSP) targeting an area of possible future development was successfully acquired in the field. At the time of acquisition, this was the largest 3D VSP survey conducted in the deepwater Gulf of Mexico.

Great efforts have been made to obtain a better tilted transverse isotropic (TTI) velocity model for the Mad Dog field using multi-wide azimuth data (Rollins et al., 2013). Yet 3D VSP surveys may offer even better opportunities to obtain high quality...

If the data are acquired as part of a conventional logging job then the acquisition does not require any additional well or rig-up time. The results shown here demonstrate...

...-dimensional (4-D) seismic and time-lapse VSP survey are widely used to monitor CO2 sequestration (Chadwick et. al. 2009, Geng et. al. 2011, John et. al. 2004, Thomas et. al. 2008).

... ABSTRACT We investigate the feasibility of simultaneous sources for 3D VSP surveys. The use of simultaneous sources for 3D VSP is attractive as it can significantly reduce the acquisition time (and, hence, the rig time). We outline an acquisition methodology for surveys of the 3D VSP type...

... Summary The sources of time-lapse offset vertical seismic profiling (VSP) surveys should be located exactly at the same positions to reliably monitor reservoir changes due to CO2 injection. However, there is often some uncertainty in source locations during time-lapse data acquisitions. We use...
