Real-Time Depth Updating of Seismic Reflection Data during Drilling Using SeismicVISION

During IODP Expedition 314, we used Schlumberger’s seismicVISION tool to monitor drilling depth progress in real time and to produce post-drilling depth corrections to our regional 3D seismic reflection data set. We collected data at four drill sites, including one site in the Kumano forearc basin that reached TD of 1401 m below seafloor, which we use as an example in this report.
