OIL FIELD HYDRODYNAMIC MODEL REFINEMENT THROUGH RELATIVE PERMEABILITY CURVES RECONSTRUCTION BY REMOTE SENSING METHODS

Remote Sensing Methods by Compressive Sensing

Compressive Sensing is a recently developed technique that exploits the sparsity of naturally occurring signals and images to solve inverse problems when the number of samples is less than the size of the original signal. We apply this technique to solve underdetermined inverse problems that commonly occur in remote sensing, including superresolution, image fusion and deconvolution. We use l 1-...

Prediction of three-phase oil relative permeability through a sigmoid-based model

We present a novel methodology for the prediction of three-phase oil relative permeability, kro, through a sigmoid-based model. This modeling choice allows us to incorporate key effects of the pore-scale phase distributions into the proposed effective empirical model for kro. Our sigmoid-based model is able to reproduce: (i) oil remobilization induced by gas injection in water-wet media; (ii) a...

Flood hazard zones using 2d hydrodynamic modeling and remote sensing approaches

Increasing frequency and severity of flooding demands identification of flood hazard zones in Kalilangan, Bukidnon in response to the echoing need of better disaster preparedness via enhancing the understanding and awareness of the public on flood characteristics by integrating the use of two-dimensional hydrodynamic modeling and remote sensing. Flood simulation was carried out in a two-dimensi...

An 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...
