... the computed fault probability using DL architectures under different scenarios. The designed scenarios aim to highlight the leading factor that may affect the accuracy and resolution of seismic image segmentation. The proposed comparisons are applied to one marine seismic survey from New Zealand and one land...

... transverse isotropy (VTI) velocity model. The algorithm uses the travel time and polarization angle of the data and then minimizes the residual by updating the velocity model. The resolution of the velocity model update gradually increases during the iteration. The workflow provides intuitiveness...

... In the imaging process, ignoring the effects of attenuation and anisotropy will reduce the quality and resolution of the imaging profile. In this paper, we present a Q -compensated least-squares reverse time migration method in viscoacoustic VTI media ( Q -VTI-LSRTM) using the pure qP-wave...

... Structural and stratigraphic interpretations are often limited by seismic resolution. Reservoir characterization is also highly dependent on the quality and resolution of the seismic. Here we describe a post-imaging inversion method for broadening the seismic bandwidth. The method was inspired...

... terranes. However, the conventional muon detector is bulky and often requires a long observation time to accumulate a statistically significant number of muon events. This study presents a new concept of muon detector with smaller sensor arrays and adjustable angular resolutions for improved portability...

...., refraction tomography) is insufficient, as it does not provide the required lateral resolution. Using only reflection data is equally insufficient, as it does not provide the required vertical resolution. We present a tomographic approach for simultaneously resolving the shallow and deep subsurface...

... Seismic field data suffer from Low Resolution (LR) image quality. This is due to the limited number of sensors used in a given seismic survey, as well as physical and technological limitations of the sensors. To obtain high-resolution (HR) images, either higher density acquisitions are carried...

... The identification of deepwater fan systems as hierarchical has improved the predictability of rock property distributions from sparse (well log) and low resolution (seismic) datasets. Underlying the definition of geologic hierarchy is the assumption that units within a level of the hierarchy...
