摘要：

The Bright Spots of the September-October 2015 issue of Geophysics informs readers about topics ranging from joint inversion of resistivity and gravity data to improved edge enhancement in magnetic data, and to from improved finite-difference elastic modeling with topography to Marchenko imaging with both internal and free-surface multiples. Zhang and Revil present a '2D joint inversion of geophysical data using petrophysical clustering and facies deformation'. The authors pose the geophysical inverse problem in terms of Gaussian random fields with mean functions, which are controlled by petrophysical relationship and covariance functions controlled by a prior geologic cross section, including the definition of spatial boundaries for the geophysical facies.
