Comparing Geostatistical Seismic Inversion Based on Spectral Simulation with Deterministic Inversion: A Case Study [PDF]

open access: yesIranian Journal of Oil & Gas Science and Technology, 2014
Seismic inversion is a method that extracts acoustic impedance data from the seismic traces. Source wavelets are band-limited, and thus seismic traces do not contain low and high frequency information.

Amplitude-Versus-Angle (AVA) Inversion for Pre-Stack Seismic Data with L0-Norm-Gradient Regularization

open access: yesMathematics, 2023
Amplitude-versus-angle (AVA) inversion for pre-stack seismic data is a key technology in oil and gas reservoir prediction. Conventional AVA inversion contains two main stages.

Propagator and wave-equation inversion for near-receiver material properties [PDF]

open access: yes, 2004
Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections.

Deep Convolutional Neural Network With Attention Module for Seismic Impedance Inversion

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Seismic inversion is an approach to obtain the physical properties of the Earth layers from the seismic data, which aids in reservoir characterization. In seismic inversion, spatially variable physical parameters, such as impedance ($Z$), wave velocities
