To improve image resolution, we evaluated a methodology of compensating for attenuation (⁠ ∼ 1 q ⁠) effects in reverse time migration (⁠ q rtm). the q rtm approach worked by mitigating the amplitude attenuation and phase dispersion effects in source and receiver wavefields.

Pdf Q Compensated Reverse Time Migration Nevertheless, it includes coupled dissipation and dispersion terms, making it inappropriate for implementingq compensated reverse time migration (rtm). therefore, we derive an equivalent gsls viscoacoustic wave equation that decouples amplitude dissipation and phase dispersion effects, which can be solved using the fd method. To overcome this problem, we propose a novel explicit q compensation scheme. the main advantage of the proposed compensation operator is that its order is space invariant, making it more suitable for handling complex heterogeneous attenuation media. Purpose: this page introduces q compensated reverse time migration (q rtm), explaining the physical basis for q compensation, the constant q attenuation model, and the advantages of q rtm over standard acoustic rtm. To enhance the imaging quality for complicated structures, we develop several effective improvements for anisotropic attenuation effects in reverse time migration (q rtm) on surface and vertical seismic profiling (vsp) acquisition geometries.

Frequency domain q compensated reverse time migration (fq rtm). both the forward modeling and rtm are based on frequency domain finite difference algorithm. all the codes are written with matlab language. the codes were tested on windows 10, with matlab r2014a. The existing stable q rtm method costs twice as much computing time and memory compared to the traditional q rtm. in this letter, we propose a new q rtm method to address the above issues simultaneously. We present the cu rtm, a cuda based code package that implements rtm based on a set of stable and efficient strategies, such as streamed cufft, checkpointing assisted time reversal reconstruction (catrc) and adaptive stabilization. In this study, we propose a multi task learning (mtl) framework that leverages data driven concepts to address the issue of amplitude attenuation in seismic records, particularly when dealing with instability during the q rtm (reverse time migration with q attenuation) process.
