Abstract
A method is disclosed for converting seismic data obtained at known points to synthesized seismic traces obtainable at arbitrarily selected points. Two dimensional seismic data are converted to dense three dimensional data with the aid of a programmed computer to permit generation of arbitrary views of a particular geologic structure as well as a mathematical representation of the structure. The data is used to locate potential drilling and mining locations for drilling oil or other minerals. In order to provide accurate interpolation from the sparse two dimensional data, both apparent and true dip characteristics are obtained for the surveyed structure, and seismic trace data for a desired point are synthesized as a function of the dip of the surveyed structure. The dip characteristics are obtained from partial derivatives of the two dimensional data in specified coordinate directions. A three dimensional surface corresponding to the dip characteristics is obtained by a least squares fitting technique. The data obtained at the known points are weighted both by distance from the desired point and the semblance coefficients associated with dip for these points to synthesize the desired data.
