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 کاملUniversal Capillary Pressure and Relative Permeability Model from Fractal Characterization of Rock
Capillary pressure and relative permeability are important parameters in geothermal reservoir engineering. It is essential to represent capillary pressure curves mathematically in an appropriate way. The Brooks-Corey capillary pressure model has been accepted widely, however it has been found that the Brooks-Corey model cannot represent capillary pressure curves of The Geysers rock samples. In ...
متن کاملAn Efficient Method for Determining Capillary Pressure and Relative Permeability Curves from Spontaneous Imbibition Data
In this paper, a very efficient method, called single matrix block analyzer (SMBA), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (SI) data. SMBA mimics realistically the SI tests by appropriate boundary conditions modeling. In the proposed method, a cuboid with an identical core plug height is considered. The equal dimensions of...
متن کاملEffects of heterogeneities on capillary pressure-saturation-relative permeability relationships.
In theories of multiphase flow through porous media, capillary pressure-saturation and relative permeability-saturation curves are assumed to be intrinsic properties of the medium. Moreover, relative permeability is assumed to be a scalar property. However, numerous theoretical and experimental works have shown that these basic assumptions may not be valid. For example, relative permeability is...
متن کاملDetermination of Resistivity Index, Capillary Pressure, and Relative Permeability
It is known that the three important parameters: resistivity, capillary pressure, and relative permeability, are all a function of fluid saturation in a porous medium. This implies that there may be a correlation among the three parameters. There have been many papers on the approach to inferring relative permeability from capillary pressure data. However the literature on the interrelationship...
