The determination of permeability in heterogeneous and anisotropic reservoirs is a complex problem, because core samples and well test data are usually only available for limited number of wells. This paper presents hydraulic flow units and flow zone indicator for predicting permeability of rock mass from core and well log-data. The concept is applied to some uncored wells/intervals to predict ...

The prediction of porosity is achieved by using available core and log data; however, the estimation of permeability is limited to the scare core data. Hence, porosity and saturation data through the framework of flow units can be used to make an estimation of reservoir permeability. The purpose of this study is to predict the permeability of a carbonate gas reservoir by using physical-based em...

Unit A of Kurra Chine Formation has been studied in the well Shaikan - 4 (SH-4) at Oilfield Northern Iraqi Kurdistan Region. The available conventional wireline log data and existed core test values have used to characterize reservoir properties unit determine flow efficiency reservoired fluids. dolomite anhydrite dominated lithology contains low percentages shale except upper most part which c...

Understanding the permeability-porosity relationships is key to improving reservoir prediction and exploitation especially in carbonate reservoirs, which are known for their complex textural diagenetic variation. Rock type classifications have long been proven be an effective technique establishing permeability- porosity relationships, enhance capability capture various flow behavior uncored zo...

The Oligo-miocene Asmari formation is one of the most important hydrocarbon reservoirs in the southwest of Iran. In order to evaluate reservoir quality and the factors controlling reservoir properties, detailed geological and petrophysical studies were carried out on 242 m of core samples from Asmari reservoir. This study is a part of a larger project that examines depositional history and rese...

Abstract This study has been accomplished by testing three different models to determine rocks type, pore throat radius, and flow units for Mishrif Formation in West Qurna oilfield Southern Iraq based on full diameter cores from 20 wells. The that were used this Lucia type classification, Winland plot was utilized the radius depending mercury injection test (r35), (FZI) concepts identify which ...

OBJECTIVE To compare mortality rates for individuals with diabetes with and without a history of foot ulcer (HFU) and with that for the nondiabetic population. RESEARCH DESIGN AND METHODS This population-based study included 155 diabetic individuals with an HFU, 1,339 diabetic individuals without an HFU, and 63,632 nondiabetic individuals who were all followed for 10 years with mortality as t...

Abstract The present work describes and evaluates the reservoir quality of sandstone Nubia Formation at Gebel Abu Hasswa outcrop in southwest Sinai, Egypt. Hydraulic flow unit (HFU) electrical (EFU) concepts are implied to achieve this purpose. Paleozoic section made up four formations has been studied. oldest is Araba followed by Naqus (Nubia C D) overlay Durba, Ahemir Qiseib B), where Lower C...
