Wavefield decomposition of seabed node marine recordings

摘要

We test two methods for 3D wavefield decomposition of marine seismic data recorded on multicomponent sensors in a seabed node. The methods work on traces from one single shot into the node. Here, multicomponent refers to a combination of sensors that includes two or more closely spaced sensors such as a hydrophone, a geophone, an accelerometer, a rotational seismometer, a pressure derivative configuration of hydrophones, or a vertical particle velocity derivative configuration of hydrophones or geophones. The derivative can be a first-order derivative, a second-order derivative, or a higher-order derivative.
