Prismatic wave contains a lot of subsurface information that primary can not reach. In this paper, prismatic wave is used alone for imaging in order to improve the inversion speed of high and steep structure. Under the guidance of this idea, a prismatic waveform inversion (PWI) method is proposed.

Prismatic and full-waveform joint inversion
Applied Geophysics, 2016Prismatic wave is that it has three reflection paths and two reflection points, one of which is located at the reflection interface and the other is located at the steep dip angle reflection layer, so that contains a lot of the high and steep reflection interface information that primary cannot reach.

Joint Gaussian processes for inverse modeling
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017Solving inverse problems is central in geosciences and remote sensing. Very often a mechanistic physical model of the system exists that solves the forward problem. Inverting the implied radiative transfer model (RTM) equations numerically implies, however, challenging and computationally demanding problems.

Incorporating anisotropy in joint migration inversion
SEG Technical Program Expanded Abstracts 2014, 2014Summary Joint Migration Inversion (JMI) is a recently developed full wavefield inversion method that is used to simultaneously estimate reflectivities and velocities in an iterative manner. In its current implementation JMI assumes an isotropic medium.

Joint inversion for correlated models in linear inverse problems
2009Inverse problems arise in many fields. They are usually ill-posed since they often violate one or more of Hadmard's three conditions for well-posedness: existence, uniqueness and stability. In this thesis, we propose a new method for computing approximate solutions in certain linear inverse problems.

Joint facies and reservoir properties inversion
GEOPHYSICS, 2018I have developed a joint inversion of seismic data for the simultaneous estimation of facies and reservoir properties, such as porosity, mineralogy, and saturation. The inversion method is a Bayesian approach for the joint estimation of facies and reservoir rock/fluid properties based on the statistical assumption of mixtures of nonparametric ...

Inverse scattering problem: Back-projection, beamforming, and joint migration-inversion
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016There are three physical mechanisms in wave propagation (geometric spreading, absorption, and scattering) determining the energy and characteristics of the waveform. Understanding of wave scattering is definitely the hardest one and thereinafter bears the greatest potential to give rise the richest information about the internal structure of the target
