Vallazza research well: 3D-RVSP seismic survey. – CEE Research Project. This
Project required a large amount of technical and human resource, to realize an
experimental survey, with a 500 station units spread configuration. The main goal
was the validation of the 3D Seismic While Drilling. The spread configuration is
surely unusual: it consists in 2 circles centred on the well and 2 branches crossed
on the well too. The units pattern follow a saw-teeth shape, each segment
orthogonal to the radius of the circles, of 1000 and 2000 m length respectively. The
operation scheduling, people, instrumentation, acquisitions and data management
followed the expected flow without problems. There was some difficulty solving the
data management problems, due to the huge amount of them: over 130 Gbyte.
