摘要:ABSTRACT(#br)Improving the seismic time–frequency resolution is a crucial step for identifying thin reservoirs. In this paper, we propose a new high‐precision time–frequency analysis algorithm, synchroextracting generalized S‐transform, which exhibits superior performan...

摘要:ABSTRACT(#br)In this paper, we deduced the corresponding first‐order velocity–stress equation for curvilinear coordinates from the first‐order velocity–stress equation based on the modified Biot/squirt model for a two‐dimensional two‐phase medium. The equations are...

摘要:ABSTRACT(#br)Based on the fact that the Hankel matrix representing clean seismic data is low rank, low‐rank approximation methods have been widely utilized for removing noise from seismic data. A common strategy for real seismic data is to perform the low‐rank approximations...

摘要:ABSTRACT(#br)Differential compaction has long been used by seismic interpreters to infer subsurface geology using knowledge of the relative compaction of different types of sediments. We outline a method to infer the gross fraction of shale in an interval between two seismic...

摘要:ABSTRACT(#br)Reverse time migration of multiples can be used to construct subsurface structures where primaries cannot illuminate well. However, the images generated using multiples suffer from severe artefacts due to the cross‐talks created by interference among unrelated m...

摘要:ABSTRACT(#br)In mineral exploration, increased interest towards deeper mineralizations makes seismic methods attractive. One of the critical steps in seismic processing workflows is the static correction, which is applied to correct the effect of the shallow, highly heteroge...

摘要:ABSTRACT(#br)In an acoustic transversely isotropic medium, there are two waves that propagate. One is the P‐wave and another one is the S‐wave (also known as S‐wave artefact). This paper is devoted to analyse the S‐wave in two‐dimensional acoustic transversely isot...

摘要:ABSTRACT(#br)A challenge in microseismic monitoring is quantification of survey acquisition and processing errors, and how these errors jointly affect estimated locations. Quantifying acquisition and processing errors and uncertainty has multiple benefits, such as more accur...

摘要:ABSTRACT(#br)We derive a governing second‐order acoustic wave equation in the time domain with a perfectly matched layer absorbing boundary condition for general inhomogeneous media. Besides, a new scheme to solve the perfectly matched layer equation for absorbing reflection...
