Borehole Seismic while Sampling Using FO Technology

Resolving Structural Uncertainty using DAS VSP Survey in Central Australia

“…The focus of this paper is the Rig Source and the Offset VSPs, acquired in the Bauer appraisal well (annotated in by the black rhomb). The choice to acquire data with both hDVS and conventional downhole seismic tools was governed by the requirement for finely sampled shallow imaging which is a forte of the hDVS system and can be acquired at a much faster rate than a conventional tool (Kimura and Galybin, 2017;Kimura et al, 2016). Nevertheless, presence of the conventional sensor was crucial in validating the hDVS response and deriving the image of the subsurface.…”
