Abstract
Computing device, computer instructions and method for denoising seismic data recorded with seismic receivers. The method includes receiving the seismic data recorded with the seismic receivers, wherein the seismic data is recorded in a time-space domain; applying with a computing device a high resolution transform to the seismic data in the time-space domain to obtain transformed seismic data in a different domain than the time-space domain, such that the method is amplitude preserving; determining regions of noise and regions of true signal in the transformed seismic data; scaling down the regions of noise; and reverse transforming the transformed seismic data to the time-space domain.
