... We have developed a method for synthesizing deep-domain seismic records, which is achieved by constructing deep-variable seismic wavelets at different depths. This method ensures that seismic records can be directly synthesized in the depth-domain. On this basis, we further constructed a post...

The conventional reflection coefficient inversion assumes that the seismic wavelet is time-invariant, but due to the influence of factors such as stratum absorption and attenuation, the actual seismic wavelet will change when it propagates in the underground medium. If the time-varying nature...

... ABSTRACT In this work, we propose a deep learning based data-driven method for high resolution inversion of seismic data. The method splits the inversion into two subproblems: one inverts the seismic wavelet and the other for reflectivity. Using a partially learned approach, the proposed...

... ABSTRACT There are few seismic wavelets that have an exact inverse filter for deconvolution, but one of these is an exponentially damped sinusoid. As shown by Lines and Treitel (1983) this wavelet has an exact 3-term inverse. Unlike most seismic wavelets, a Wiener deconvolution filter can...

However, the conventional seismic inversion methods in the time domain are not suitable in the depth domain due to the seismic wavelet in the depth domain is time-variant and depending on medium velocity. To address this issue, we proposed a pragmatic...
