A Universal Capillary Pressure Model: Verification and Application
نویسندگان
چکیده
Abstract A universal capillary pressure model developed from fractal modeling of a porous medium was verified using the experimental data of capillary pressure curves of rock samples from The Geysers geothermal field. The capillary pressure curves were measured using a mercury intrusion technique. The results showed that the universal model could represent the capillary pressure curves of The Geysers rock satisfactorily while the frequently-used Brooks-Corey capillary pressure model could not. The values of fractal dimension, a representation of rock heterogeneity, were inferred from the match of the universal capillary pressure model to the experimental data.

A model for specification, composition and verification of access control policies and its application to web services
Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...
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 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 کاملApplication of the Phenomenological Model to Electrophoretic Mobility in Mixed Solvent Electrolyte Systems in Capillary Zone Electrophoresis
The phenomenological model of Khossravi and Connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. The accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (APMD). The obtained APMD for correlative and predictive studies ...
