sinden 4d

with a sparse OBN monitor (Figure 1). gatotkaca 4d After wavefield separation of OBN and 4D binning to create two realisations of TS and OBN data, regions of 4D noise are successfully attenuated in the weighted stack. lokasi 4d There is little 4D signal damage evident in the difference of the weighted stack against the average of the upgoing and downgoing 4D differences
