60. To aid in performing an NMO correction to the noisy seismic data on the left, the semblance plot on the right was generated. a. Describe what a semblance analysis does (you may want to use a sketch on the CMP gather to explain)? b. Using theses plots, approximately what intercept time and stacking velocity would you use to perform the NMO correction? CMP Gather Semblance Semblance Contour 0.1 0.1 0.11 0.2 02 0.2 0.3 0.3 0.3 04 04 04 ime (5) 0.5 Interceptime (5) 0.5 Intercept time (5) 0.5 06 0.6 0.6 0.7 0.7 0.7 0.8 0.8 0.81 0.9 0.9 0.9 0 600 500 200 400 Offset (m) 500 1000 1500 2000 2500 3000 Velocity (m/s) 1000 1500 2000 2500 3000 Velocity (m/s)
