  • Static correction method for exploration seismic data using first arrivals of seismic waves
    Patent number: 6501703
    Abstract: A shorter spatial wavelength static correction method for exploration seismic data using first arrivals according to the invention includes the steps of: based on a quadratic curve fitting to the first arrivals, which are picked up from seismic wave records of receiver gathers after the field statics, obtaining the difference &Dgr;i,j between the observed first arrival time tij of the receiver point j with respect to the shot point i and the corresponding time value of the fitted quadratic curve; and forming the original matrix &Dgr; having m×n elements &Dgr;i,j, where n is the total number of shot points and m is the total number of receiver points of the line; substituting the elements of each row by the difference between the value of each element and the row average; and substituting the elements of each column by the difference between the value of each element and the column average; repeating the iteration until less than a predetermined error; the sum of the averages of the ith row for all itera
