Optimisation of Prestack Scaling Prior to Seismic Inversion
Proceedings, 2018Summary Prestack scaling is an essential step which is used to correct the amplitudes of seismic reflection data as part of quantitative interpretation workflows such that they honour the background AVO behaviour. The resulting scalers are fed into prestack seismic inversion algorithms to yield better results.

Azimuthal Prestack Seismic Inversion for Fracture Parameters Based on L1–2 Norm Regularization
IEEE Transactions on Geoscience and Remote SensingThe inversion of fracture parameters, using the variation in prestack seismic amplitude with incident angle and azimuth (AVAZ), is a primary method for predicting subsurface fractures. However, the inversion for fracture parameter is inherently ill-posed,

Simultaneous prediction of the geofluid and permeability of reservoirs in prestack seismic inversion
Geophysics, 2023ABSTRACT Geofluid discrimination and permeability prediction are indispensable steps in reservoir evaluation. From the perspective of prestack seismic inversion, predicting fluid indicators is an effective method for obtaining fluid properties directly from seismic data. In contrast, the direct prediction of permeability from observed
