Geophysical data acquisition - OGS

Therefore, having beside a high elevation spread and a datum plane quite deeper,
a lot of effort has gone into studying and designing the survey, first of all using the
already existing informations (seismic lines, up-hole survey, stacking chart,
dromochrones and thematic maps) and then the foreseen stratigraphy. After the
ray-tracing, this set of elements allowed to plan the data recording geometries,
fitting the basis extension with high channel number (48), using the Summit
telemetric system and a Hydrapulse as source.
Moreover, together with this new approach using short refraction for a while
drilling survey, data are dynamically correct with Seisbit ® information until the
datum plane depth.
The ASTI group worked in collaboration with more crews up to 24 people, most of
them OGS senior technicians and engineers and some people from the contractors
companies.
After the testing phases of the Seisbit ® 2, innovation studying and designing are
pursued, to improve the automation capabilities and the data storage and
elaboration features in field.
