Automated Seismic Acquisition Geometry Design for Optimized Illumination at the Target: A Linearized Approach
Autor: Gerrit Blacquière, D.J. Verschuur, Sixue Wu
Publikováno v: IEEE Transactions on Geoscience and Remote Sensing, 60
In seismic exploration methods, imperfect spatial sampling at the surface causes a lack of illumination at the target in the subsurface. The hampered image quality at the target area of interest causes uncertainties in reservoir monitoring and produc

Localizing microseismic events on field data using a U-Net-based convolutional neural network trained on synthetic data
Autor: N. A. Vinard, Guy Drijkoningen, D.J. Verschuur
Publikováno v: Geophysics, 87(2)
Hydraulic fracturing plays an important role when it comes to the extraction of resources in unconventional reservoirs. The microseismic activity arising during hydraulic fracturing operations needs to be monitored to both improve productivity and to

Joint Inversion of Acoustic and Electromagnetic Wave fields
Autor: Eva M. L. Scherders, D.J. Verschuur, K.W.A. van Dongen
Publikováno v: 2022 IEEE International Ultrasonics Symposium (IUS).
Imaging by inversion of acoustic or electromagnetic wave fields have applications in a wide variety of areas, such as non-destructive testing, biomedical applications, and geophysical exploration. Unfortunately, each modality suffers from its own app

Closed-loop surface-related multiple estimation with full-wavefield migration-reconstructed near offsets for shallow water
Autor: D.J. Verschuur, Dong Zhang
Publikováno v: GEOPHYSICS. 86:WC21-WC30
Reliably separating primary and multiple reflections in a shallow-water environment (i.e., 50–200 m water depth) still remains a challenge. The success of previously published closed-loop surface-related multiple estimation (CL-SRME) depends heavil

Simultaneous joint migration inversion as a high‐resolution time‐lapse imaging method: Feasibility and robustness study
Autor: Shan Qu, D.J. Verschuur
Publikováno v: Geophysical Prospecting. 69:1455-1472
The conventional time‐lapse processing workflow is usually sensitive to the non‐repeatable uncertainties between different vintages caused by noise, acquisition designs and independent processing. Therefore, in order to reduce these non‐repeata

Fast local primary-and-multiple orthogonalization for surface-related multiple leakage estimation and extraction
Autor: Yangkang Chen, Dong Zhang, D.J. Verschuur
Publikováno v: GEOPHYSICS. 86:V353-V360
Surface-related multiple elimination (SRME) has proven to be a robust surface multiple and primary estimation tool for decades. However, surface-related multiple leakage is still commonly observed in SRME-processed results due to imperfect multiple p

Local primary-and-multiple orthogonalization for leaked internal multiple crosstalk estimation and attenuation on full-wavefield migrated images
Autor: Mikhail Davydenko, Ali M. Alfaraj, Yangkang Chen, Dong Zhang, D.J. Verschuur, Shan Qu
Publikováno v: GEOPHYSICS. 86:A7-A13
An important imaging challenge is creating reliable seismic images without internal multiple crosstalk, especially in cases with strong overburden reflectivity. Several data-driven methods have been proposed to attenuate the internal multiple crossta

Simultaneous joint migration inversion for high‐resolution imaging/inversion of time‐lapse seismic datasets
Autor: Shan Qu, D.J. Verschuur
Publikováno v: Geophysical Prospecting. 68:1167-1188
The current time‐lapse practice is to exactly repeat well‐sampled acquisition geometries to mitigate acquisition effects on the time‐lapse differences. In order to relax the rigid requirements on acquisition effects, we propose simultaneous joi
