Abstract：Seismic curvature attribute analysis is a new method for fracture prediction based on the bend degree of seismic rellected events on the interface of compact and brittleness stratum.Curvature can be expressed in term of mathematics as dip and the derivation of dip, so seismic curvature cube can be obtained by two time derivations on original seismic cube.We put forward a new twice scan method respectively on plane and curve plane combining with multi-windows scan technology which possess the edge preservation characteristic, to obtain higher precision curvature cube.This method can extract the bend degree of seismic reflected events both continuity with little strain and discontinuity with faults.Example results of real data prove that our method shows better low relief structures from seismic reflections, and highlights details of fautt edges and fractures.
