The method of this invention sequentially determines dips and corresponding estimated dip components of traces in a panel of data. The method can be applied to any data which can be represented as a function of two coordinates. In particular, the method of this invention can be applied to seismic data traces. The method of this invention in one embodiment sums data on traces along a preselected range of trial dips on a panel of data. The energy of the summed data with their corresponding trial dip are then displayed. The dip which has the peak of maximum energy on the display is then selected as a valid dip. An estimated dip component of the selected dip is then determined and subtracted from the traces along the selected dip. The process is then repeated, sequentially, determining a dip and an estimated dip component from the panel of data until the desired number of dips and estimated dip components are determined or the residual energy of the remaining data on the traces are below a preselected value. After the dips and estimated dip components are determined from the panel of data, the information can then be used to place an interpolated trace within the panel of data, to create a new panel of data having uniform spacing between the traces if the original panel of data had some non-uniform spacing, and/or to enhance the traces by creating a new panel of data having only the determined dips and estimated dip components thereby removing from the data panel randomly distributed noise. |
