Using DAS for reflection seismology-lessons learned from three field studies by Freifeld, B.M., Dou, S., Ajo Franklin, J.B., Robertson, M., Wood, T., Daley, T., White, D.J., Worth, K., Pevzner, R., Yavuz, Sinem, Correa, J., McDonald, S.

“…For surface reflection seismology, the wide spatial aperture afforded by DAS is a primary motivation for its application, however the lower SNR of DAS has proven to be a significant impediment to acquiring data that can replace conventional receiver arrays. …”

Comparison of different traveltime approximations for VTI media in context of poststack diffraction imaging by Khoshnavaz, M., Bona, Andrej, Urosevic, Milovan

“…In this article, we propose to take anisotropy into account in 2D poststack domain by considering P-wave non-hyperbolic diffraction traveltime approximations for VTI media, previously developed for reflection seismology. Accuracy of final images are directly connected to the accuracy diffraction traveltime approximations. …”

Post-stack diffraction imaging in vertical transverse isotropy media using non-hyperbolic moveout approximations by Khoshnavaz, M., Bóna, A., Urosevic, Milovan

“…In this article, we suggest taking anisotropy into account in two-dimensional post-stack domain by considering P-wave non-hyperbolic diffraction traveltime approximations for vertical transverse isotropy media, previously developed for reflection seismology. The accuracy of the final images is directly connected to the accuracy of the diffraction traveltime approximations. …”
