Relative Permeability Measurement in Rock Fractures
The petroleum industry always requires precise measurement of relative permeability. When it comes to the fractures, the measurement becomes extremely difficult since the saturation in the fractures is hard to calculate. In this study, we are aiming to provide a machine learning approach to distinguish voxel-based water and gas in rock fractures based on Computed Tomography. This research is di...
متن کاملCoupled mechanical–geophysical monitoring of rock fractures and damage
The study of rock fractures is essential in evaluating stability of underground structures, understanding earthquakes, and assessing storage and transport of oil and gas in rock formations. Geophysical monitoring techniques, particularly compressional and shear wave propagation, can probe the internal structure of rock and fractures remotely and nondestructively and can provide insight into fra...
متن کاملWhole rock and tectonic setting of gneisses from the eastern Salmas (west of Urmia lake), NW Iran
The garnet calc-silicates at Baba-Nazar are located in the NE of Takab, Sanandaj- Sirjan zone. Anhedral to euhedral green colored garnets is a characteristic feature of these Calc-silicates. Mineral chemistry shows that garnets are Andradite- Grossular and contain more than 13% uvarovite. The high chromium content garnet, Cr-Spinel that have relatively Cr rich core than the rim, sulfide opaque ...
متن کاملSegmentation for rock fractures based on ARMA model
Rock fracture mapping is very important in many applications related to rock mechanics. The toughest task is the extraction of the fractures from the images of the rocks. Time series model has been used in this paper for segmentation of fractures from the rock images. The model is compared with orthodox edge detection algorithms. A first order autoregressive image model has been implemented. Th...
