values

• The definition of the initial distribution extracted from the analog-wells is crucial for the success of the inversion process

• It is very important to have a clear idea of what could be our geological model to infer the lithology/facies for better definition of the zoning model or properties distribution

• The proposed method achieved very good results


Broadband data recording

Land: • New generation of vibrators extending the frequency content to ultra low frequency side (down to 1.5 Hz) and to the

higher frequency side. • New generation of geophones (MEMS - Micro Electro-Mechanical System) capable of recording very low frequencies Marine: • New generation of streams, streams with variable depth, dual sensors streams and new techniques for deghosting


Seismic Inversion with Broadband acquisition

Broadband allows a higher-fidelity inversion of seismic back to the underlying rock properties and improve confidence in ability to predict and match well data


Full-azimuth 3D

Having a convenient set of subset cubes of different angles and azimuths it is possible to calculate anisotropic seismic attributes linked fracture density and

orientation

For better seismic imaging and fracture characterization, the acquisition with full range of azimuth is a key point, which

requires an orthogonal acquisition templates with a large number of source and receiver points
