Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3583546
... Three 3D borehole seismic (VSP) surveys were designed and acquired in Andrews and Ector Counties, Texas in 2019 to provide data to support the processing and interpretation of a high-fold multicomponent 3C/3D survey. The three downhole receiver well locations were chosen in available wells...

... 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...

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...

... 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...
