Seismic While Drilling

Flavio Poletto worked from 1984 to 2019 at the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale – OGS (former Osservatorio Geofisico Sperimentale), Italy. In 1988 he received the degree “Dottore in Fisica” from the University of Trieste. Since 1988, he has worked as a geophysicist on seismic-while-drilling (SWD) research by using the drilling noise to obtain reverse VSPs. He is the author of many papers and a monography on SWD, drill-string acoustics, co-author of patents regarding the drill-bit-noise separation for RVSP and Tunnel SWD. He received Honorable Mentions for papers selected in the category of the Best Paper in GEOPHYSICS (2001 and 2003), ASCE Best paper (MOONBIT) (2010), and “Legends-of-SWD” (2016) awards. His research activity includes borehole geophysics, acoustic and SWD, with applications extended to drilling diagnostics, geosteering, seismic interferometry, DAS, CCS, and Geothermal. Francesco Miranda received a BSc degree in Geology in 1984 and a PhD degree in Geophysics 1989 from UC Swansea (UK) with a thesis on Travel-time and Amplitude Tomography. He worked at DMT (Bochum, Germany) where he was active in research in seismic tomography, borehole seismic data acquisition and processing, processing of in seam seismic for coal fields, and special processing and acquisition techniques for surface 2D seismic. Since 1990 he has worked in the exploration and production Division at Eni in Milan, in the borehole seismic department. He has been actively involved in research in the field of Seismic While Drilling on which he is the author of many papers and in the field of cross-hole seismic and geosteering
