Lateral Constrained Prestack Seismic Inversion Based on Difference Angle Gathers
IEEE Geoscience and Remote Sensing Letters, 2021 Prestack amplitude variation with offset (AVO) inversion can provide abundant reservoir information underground, which is always implemented trace-by-trace. However, it cannot guarantee the lateral accuracy of the inversion results. To utilize the lateral difference of the angle gathers and improve the lateral resolution, the difference angle gathers ...

Phase Variance as a Seismic Quality-Control Attribute [PDF]
SensorsSeismic sensors deployed in land acquisition record wavefields that are strongly distorted by near-surface heterogeneity, which introduces trace-specific, frequency-dependent phase perturbations that persist even after advanced time processing.

Time-lapse seismic attenuation as a tool for monitoring hydrocarbons and CO2 in geological materials [PDF]
, 2011 Both laboratory experiments and theoretical models have shown seismic attenuation to be sensitive to various petrophysical properties of rock and pore fluids, making attenuation a potentially useful time-lapse attribute to measure and interpret through ...

Design &implementation of complex-valued FIR digital filters with application to migration of seismic data [PDF]
, 2006 One-dimensional (I-D) and two-dimensional (2-D) frequency-space seismic migration FIR digital filter coefficients are of complex values when such filters require special space domain as well as wavenumber domain characteristics. In this thesis, such FIR

Multiple Scenario Inversion of Reflection Seismic Prestack Data [PDF]
Proceedings, 2012 Inversion of prestack seismic data is a highly non-unique inverse problem. Many elastic models exists that fit seismic data observations equally well within the data uncertainty. In a probabilistic formulation of the inverse problem, a full description of such variability is described by the a posteriori probability distribution.

Viscoelastic Fluid Factor Inversion and Application in Luojia Oilfield Based on Broadband Impedance
Geofluids, 2021 Based on the physical quantity of log data, the accurate identification of oil- and gas-bearing properties may be caused by the prestack inversion of fluid prediction, which will affect the success rate of exploration and development.
