Statics

Some years ago, Shuki Ronen and I proposed a formalization of the statics corrections process as ``maximize the power in the stack''. With MOPLAN filters, a new formalization of the statics problem is possible, ``minimize the power in the mono-plane-annihilated stack''. Unlike the statics concept with Ronen, this new MOPLAN concept is an instance of ``geophysical inverse theory'' where the model covariance matrix is identified as a MOPLAN. Ronen and I discovered, when we dug inside the statics programs, that our principle implied techniques that were practically the same as the traditional ones. It will be interesting to see what is implied by MOPLAN statics. A data type that might validate MOPLAN statics would be where near-surface corrections and variable dip are important, but curvature is not (so migration is not also involved). Later we will see that an important MOPLAN simultaneously incorporates deconvolution.
