Figure 5.76
Model showing the effect of noise on intercept and gradient - blue points represent shale/brine sand reflections, red
points represent shale/oil sand reflections; (a-c) ¼ noise free model data (three single interface models representing different porosities
and fluid fill), (d-f) ¼ noise added to the models; (g) and (h) are projections at χ ¼ 27° and χ ¼ 11° respectively from the noisy data (data
from Roy White, personal communication).
