A low frequency deghosting method: Analysis and numerical tests
Wang, Ying; Ramirez, Adriana Citlali; Osen, Are (Journal article; Peer reviewed, 2017)The low-frequency component of seismic data can be beneficial for several reasons: improved signal penetration into the earth, enhanced resolution, and better constrained inversion results. We have developed a detailed ... -
Decay estimation in nonlinear hyperbolic system of conservation laws
Zaihong, Jiang; Wang, Ying (Journal article; Peer reviewed, 2011)In this paper we study some decay estimates in nonlinear hyperbolic system of conservation laws. This research is not only interesting in itself but also crucial in studying the large time behavior problem. By introducing ... -
Estimating Horizontal Resistivity Trends in Sedimentary Rocks: A Case Example from the Northern North Sea
Duffaut, Kenneth; Wang, Ying; Nordskag, Janniche Iren (Journal article; Peer reviewed, 2018)Understanding the major controlling factors on the horizontal resistivity-depth trends of sedimentary rocks in any given basin around the world are interesting from both scientific and commercial perspectives. Hence, we ... -
Global existence and decay estimates of the Boltzmann equation with frictional force
Zaihong, Jiang; Wang, Ying (Journal article; Peer reviewed, 2014)In this paper, we give the existence theory and the optimal time convergence rates of the solutions to the Boltzmann equation with frictional force near a global Maxwellian. We generalize our previous results on the same ... -
Non-orthogonal beam coordinate system wave propagation and reverse time migration
Zhu, Zhaolin; Cao, Danping; Wu, Bangyu; Yin, Xingyao; Wang, Ying (Peer reviewed; Journal article, 2019)Grid size has a significant influence on the computation efficiency and accuracy of finite-difference seismic modeling and can change the workload of reverse time migration (RTM) remarkably. This paper proposes a non-orthogonal ... -
Optimal time decay of the Boltzmann equation with frictional force
Wang, Ying; Zaihong, Jiang (Journal article; Peer reviewed, 2011)In this paper, we use the combination of energy method and Fourier analysis to obtain the optimal time decay of the Boltzmann equation with frictional force towards equilibrium. Precisely speaking, we decompose the equation ... -
Predicting horizontal resistivity trends: An example from the Barents Sea
Wang, Ying; Duffaut, Kenneth; Nordskag, Janniche Iren (Chapter, 2018)Exploring the major controlling factors on resistivity depth trends in sedimentary basins is an interesting subject from both scientific and commercial perspectives. We propose a rock-physics based workflow for predicting ... -
The specular reflective boundary problem for the Boltzmann equation with soft potentials
Wang, Ying; Jiang, Zaihong (Journal article; Peer reviewed, 2012)In this paper, we consider the specular reflective boundary problem for the onedimensional Boltzmann equation with soft potentials. It is shown that the solution converges to a global Maxwellian M+ under certain initial ...
