Reservoir fracturing or fissuring is a natural phenomenon and a major factor in many Oil engineering studies. The factors that cause the Reservoir to fracture were analyzed in Tabnak Anticline, in Fars province of Iran using the borehole images information (EMI). A nonlinear simulation and assessment model of reservoir fracturing was established using the artificial neural network (ANN) technology to simulate the structure and function of the neural network (NN) of the human brain with engineering technology. The ...

Since the resistivity and induced polarization methods have an important role for exploration of concealed lead and zinc, in order to assess the Lead and Zinc layers in an ancient mine, Karongah of Kohbanan, four geoelectrics profiles designed and surveyed in shlumberger array, so that these directions were almost vertical in compare with layers direction and they were include 14, 10, 8 and 9 sounding stations respectively. After geological assessment and one dimensional and two dimensional inverse modeling, we dr...

This paper introduces two methods, one is the element Concentration-perimeter and the other is power spectrum- perimeter method, for separating geochemical anomalies from background based on fractal approach. The variability of the element concentration and power spectrum as a function of perimeter from sample sites reveals two different fractal distributional patterns acting within two scale ranges. Therefore, these methods can be used to effectively separate geochemical anomalous areas from background. We compar...

The North part of Kashmar is located about 250 Km Southwest of Mashhad, Northeast Iran. It is part of the structural Darouneh fault zone and contains rhyolitic, andesitic, pyroclastic and lava flows. Based on results obtained from AFM and Miyashiro diagrams the igneous rocks classified as a subalkaline and calcalkaline. From the data obtained the Kashmar strike-slip fault geometry (distribution of shear fractures such as R,RЛґ,P surfaces, Riedel structures) plays an important role in controlling the location and e...

Anomaly separation plays an important role in mineral exploration. The fractal based method presented in this study provides an anomaly separation method which accomplishes anomaly separation in frequency domain. It is based on the Fourier transformation, which can be compared to a glass prism. The prism separates light into various components, each depending on its wavelength (or frequency) content. Fourier transform can be viewed as a "mathematical prism" that separates a function into various components based o...
