Fast interval velocity estimation via NMO-based differential semblance
نویسنده
چکیده
Differential semblance velocity analysis flattens image gathers automatically by minimizing the mean square difference of neighboring traces in an image volume. Implementations based on normal moveout correction as “imaging” method are relatively fast, can accomodate arbitrary acquisition geometry, and can be organized to output 1D, 2D, or 3D interval velocity models. Within the limits of its imaging methodology (mild structure, data dominated by primary events), this approach to velocity analysis appears to be robust and effective.

متن کاملAutomatic Velocity Analysis via Shot Profile Migration
Shot profile migration provides a convenient framework for implementation of a differential semblance algorithm for estimation of complex, strongly refracting velocity fields. The objective function minimized in this algorithm may measure either focussing of the image in offset or flatness of the image in (scattering) angle. Velocity estimation based on this measure of data-model consistency us...

The differential semblance method employs an objective function, which measures the error in moveout between neighboring traces. Differential semblance velocity estimators have well-defined and smooth high frequency asymptotics compared to the conventional velocity analysis. Numerical experiments with CMP gathers and layered models illustrate theoretical properties of DS objectives. (reference ...

The quality of the migration/inversion in seismic re ̄ection is directly related to the quality of the velocity macro model. We present here an extension of the differential semblance optimization method (DSO) for 2-D velocity ®eld estimation. DSO evaluates via local measurements (horizontal derivatives) how ̄at events in common-image gathers are. Its major advantage with respect to the usual cos...
متن کاملSeismic data processing in vertically inhomogeneous Tl media
The first and most important step in processing data in transversely isotropic (TI) media for which velocities vary with depth is parameter estimation. The multilayer normal-moveout (NMO) equation for a dipping reflector provides the basis for extending the TI velocity analysis of Alkhalifah and Tsvankin to vertically inhomogeneous media. This NMO equation is based on a root-mean-square (rms) a...
