Permeability Predication by using Capillary Pressure data in Carbonate Reservoir from Southern Iraqi oil field
Permeability and capillary pressures are important petrophysical properties. Permeability is one of the most important parameters for reservoir management and development. Capillary pressure data have been widely used in evaluating reservoir rock, sealing capacity, transition zone thickness, pay versus non pay, and absolute and relative permeability. We are working in this study modification tw...
متن کاملEvaluating Different Approaches to Permeability Prediction in a Carbonate Reservoir
Permeability can be directly measured using cores taken from the reservoir in the laboratory. Due to high cost associated with coring, cores are available in a limited number of wells in a field. Many empirical models, statistical methods, and intelligent techniques were suggested to predict permeability in un-cored wells from easy-to-obtain and frequent data such as wireline logs. The main obj...
متن کاملXenon NMR measurements of permeability and tortuosity in reservoir rocks.
In this work we present measurements of permeability, effective porosity and tortuosity on a variety of rock samples using NMR/MRI of thermal and laser-polarized gas. Permeability and effective porosity are measured simultaneously using MRI to monitor the inflow of laser-polarized xenon into the rock core. Tortuosity is determined from measurements of the time-dependent diffusion coefficient us...
متن کاملCalculation of Steam-water Relative Permeability Using Capillary Pressure Data
Various capillary pressure approaches such as the Purcell, Burdine, Corey, and Brooks-Corey methods were used to calculate steam-water relative permeabilities using the measured data of steamwater capillary pressure in both drainage and imbibition processes. The calculated results were compared to the experimental data of steam-water relative permeability measured in Berea sandstone. The steam-...
متن کاملPermeability and Relative Permeability in Rocks
Important features of the topology of the pore space of rocks can be usefully quantiied by analyzing digitized images of rock cross sections. One approach computes statistical correlation functions using modern image processing techniques. These correlation functions contain information about porosity, speciic surface area, tortuosity, formation factor, and elastic constants, as well as the uid...
