Transforming Fracture Characterization with Novel Sonic Reflection Imaging

3D Far field sonic imaging, a novel sonic reflection imaging analysis that identifies dip, azimuth, and distance to reflector for acoustic impedance contrast events tens of meters deep into the formation was applied in a naturally fractured heterogenous brecciated reservoir. Integration of these events with borehole image enabled interpretation of structural bed boundaries, faults and open fractures, their extension and connectivity within the reservoir. The consistency in the integration identified the fracture network extending deep into formation. The results were used to update the static discrete fracture network resulting in a production history match that had not been possible before.
