Offshore seismic and electromagnetic (EM) imaging for hydrocarbons can require up to tens
of millions of parameters to describe the 3D distribution of complex seabed geology and …

Land seismic velocity modeling is a difficult task largely related to the description of the near-
surface complexities. Full-waveform inversion (FWI) is the method of choice for achieving …

Structural joint inversion of several data sets on an irregular mesh requires appropriate
coupling operators. To date, joint inversion algorithms are primarily designed for the use on …

We discuss the use of helicopter-borne transient electromagnetic (HTEM) for a high-
resolution spatial and vertical characterization of the near surface in a structure-controlled …

Geophysical joint inversion requires the setting of a few parameters for optimum
performance of the process. However, there are yet no known detailed procedures for …

摘要重震联合反演是多地球物理数据联合反演的重要分支. 通过调研国内外重震联合方面经典和
最新文献, 从模型参数化, 联合数据类型, 反演的实现和结果评价, 优势及应用等多个角度对重震 …

A new algorithm for spatially constrained inversion (SCI) of transient electromagnetic (TEM)
data is presented. The 1D inversion of TEM soundings is regularized in a 3D sense by …

Cross-gradient joint inversion of gravity and seismic data can more accurately provide the
characteristics of subsurface density and velocity structure. The subsurface is usually …

The linear traveltime interpolation (LTI) method, one of the common methods to calculate the
wavefront traveltimes and the raypaths in complex media, is based on the assumption that …

We propose here a methodology to build near-surface velocity models by joint inversion of
traveltime and high-resolution airborne EM (AEM) data. The resulting velocity and resistivity …
