GEOP - Borehole Geophysics

Competences of this group are the promotion, development and management of innovative projects of geophysical research, including drilling monitoring methods. The research activity of GEOP is focused on borehole geophysics, wavefield propagation, passive geophysical methods, seismic interferometry, acoustics, drilling diagnostics, in particular to methodological methods to obtain, in cooperation with industry, geophysical information by the drill-bit seismic source while drilling (seismic while drilling SWD - Seisbit), in oil and gas and geothermal wells, and tunneling. The activity includes the development of new data processing algorithms, procedures and codes, the industrialization of the data processing codes, the design and the development of acquisition systems and borehole instrumentation tools for the scopes of the research and demonstrative services. GEOP supervises and manages the Piana di Toppo (PN) OGS borehole geophysical-drilling instrumented test site.
