摘要:Full waveform inversion (FWI) aims to recover the most accurate velocity components with full wave information. FWI produces nearly perfect results when the input seismic data contains enough low-frequency information. We first analyze the relationship between the gradient and th...

摘要:This work presents an automation system for detecting the presence of bottom-simulating reflectors (BSRs) and other reflectors parallel to the sea bottom in real seismograms. The system uses automatic gain control to aid the thresholding method for edge detection and segmentation...

摘要:Free-surface related multiples exist widely in marine seismic data. Imaging with multiples rather than suppression has particular benefits because multiples have more information than primaries, such as wider illumination and higher vertical resolution. One-way wave-equation base...

摘要:We present systematic sensitivity analyses of logging-while-drilling azimuthal resistivity measurements (ARM). These analyses provide us the clear images of the sensitivities of the ARM to various formation parameters, such as bed boundary, current and shoulder layer formati...

摘要:In this paper, the occurrence characteristics of the weak and weathered overburden, and hydrogeological features, are first analyzed in a research coal field. The overburden failure law and the development of ‘Three Zones’ are studied through physical model tests, and the ru...

摘要:Formation evaluation of clastic reservoirs has always had some difficulties. This issue for a clastic gas reservoir from North-East Iran has already made some problems for petrophysicists. Therefore, this paper presents a basic and consequential strategy for (1) solving the probl...

摘要:Fractal dimension can effectively describe the microstructure of self-similar fractal porous media, and it is of great significance to predict their macroscopic mechanical properties by different fractal dimensions. Based on fractal theory and the Mori–Tanaka method, homogen...

摘要:In order to study the damage induced by rock blasting, a numerical simulation method based on the Johnson–Holmquist II (JH-2) damage model combined with the arbitrary Lagrangian–Eulerian (ALE) method is proposed. The process of dynamic breakage and damage evolution of Barre ...

摘要:In this paper the latest approaches to automated history matching were applied to a real brown field with multiple responses, located in the south part of Iran. A modified support vector machine was employed to create a proxy model in which 44 model parameters were incorporated b...

摘要:The Jiaodong Peninsula in North China is an important Chinese gold mining region, and deposits are mainly controlled by the northeast trending Sanshandao, Jiaojia, and Zhaoyuan–Pingdu faults. Most previous study results proposed the relationships of the known deposits, contr...
