Capturing the Value of Source-Over-Streamer Acquisition for Velocity Model Building at Barents Sea

The source-over-streamer configuration has been designed to improve pre-processing of the seismic data leading to high-resolution imaging. It also leads to new residual moveout information, unique in its high quality and density. By adding a front source to the original design, long offset information is now available for full waveform inversion velocity update. The combination the reflection information from the clean common imaged gather and the diving wave from the long offset allows a high-resolution anisotropic model to be obtained.
