Results of studying the azimuthal anisotropy of the Paleozoic basement with VSP technique at the Bystrovka vibroseismic test site

Abstract

At present due to depletion of reserves in the majority of Western Siberia oil and gas fields, with reservoirs mainly related to lower Cretaceous and Jurassic section interval, the basement intervals present primary scientific and practical interest for prospecting and exploration. At the Bystrovka vibroseismic test site (Novosibirsk region), the Paleozoic basement occurs at depth of about 10 m. This allowed investigating its elastic properties with shallow seismic technique using VSP. Results of these investigations are presented in the present paper.
