摘要:This paper analyses the details of a procedure for the numerical integration of Hankel transforms in the calculation of the electromagnetic fields generated by a large horizontal loop over a 1D earth. The method performs the integration by deforming the integration path into the ...

摘要:This part 2 companion paper derives several related methods to determine pole location for guided electromagnetic waves in a planarly layered medium in the quasi-static approximation. Such analysis can be useful for the numerical evaluation of field representation integrals of la...

摘要:We develop a two-stage method to invert induced polarization (IP) data. First, DC resistivity data are inverted to recover a background resistivity that is used to generate a sensitivity matrix for the IP inversion. The second stage accepts the background resistivity as the true ...

摘要:On the basis of geophysical imaging surveys, including geomagnetic and geoelectrical resistivity, possible archaeological remains and their spatial parameters (i.e., location, extension, depth and thickness) were explored to provide useful data for future excavations on the Upper...

摘要:We propose a new approach to update fault seal estimates in fluid flow simulation models by direct use of 4D seismic amplitudes calibrated by a well geological constraint. The method is suited to compartmentalized reservoirs and based on metrics created from differences in the 4D...

摘要:Diffractions of P and SV waves on irregular bathymetries are studied using the indirect boundary element method. This allows us to evaluate the complete displacement field by the superposition of a free field plus a diffracted one. Six elemental bathymetries are analyzed in the f...

摘要:This paper introduces the use of the ensemble smoother as a method to invert time-lapse seismic data into pressure and saturation fields. The proposed method uses engineering information described in terms of reservoir flow simulations to generate samples of the prior uncertainty...

摘要:Pore facies analysis is a useful method for the classification of reservoir rocks according to pore geometry characteristics. The importance of this method is related to the dependence of the dynamic behaviour of the reservoir rock on the pore geometry. In this study, pore facies...

摘要:We investigate the use of Tikhonov regularization with the minimum support stabilizer for underdetermined 2D inversion of gravity data. This stabilizer produces models with non-smooth properties which is useful for identifying geologic structures with sharp boundaries. A very imp...
