The broad objective of this study is to determine the limitations of the three-phase relative permeability estimation technique by using the experimental approach. In order to achieve this goal, three-phase relative permeability experiments were conducted on a Berea sandstone core plug by using brine, hexane and nitrogen gas. An unsteady-state analytical technique and a numerical technique where a black oil simulator was coupled with a global optimization algorithm in a least squares manner was used to compute three-phase relative permeabilities. It has been found that basic assumptions of linear flow and monotonic saturation changes, required for three-phase extensions of two-phase Johnson-Bossler-Nauman (JBN) theory, are violated in the displacement experiments, leading to errors in computed relative permeabilites even at high rates.

Reservoir analysis by well log data Kök, Mustafa Verşan; Ersoy, Gizem (Informa UK Limited, 2005-04-01) The aim of this research is to describe and characterize the reservoir sections by well log data. Well logs are used to examine the porosity, water saturation and true resistivity properties of the reservoir. Throughout the project, the data is processed using geostatistical tests that are frequency, histograms, auto-correlation, cross-correlations, linear and multiple regression analysis to find the relations between the variables. Statistical analyses are performed using SPSS software. From the output of ...
Thermogravimetry of selected bentonites Kök, Mustafa Verşan (Informa UK Limited, 2002-10-01) In this research the application of thermal analysis techniques (TG-DTA) to the characterization of bentonite samples is presented. The thermal behavior of 4 bentonite samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) techniques. It was observed that all bentonite samples exhibit 2 weight loss events on heating. The first weight loss event corresponds to the loss of molecular water from the exchange layer, whereas the second weight loss event corre...
Improvements on combustion properties of asphaltite and correlation of activation energies with combustion results Hicyilmaz, C; Altun, Naci Emre (Elsevier BV, 2006-06-01) Processing of Sirnak Asphaltite sample by gravity and flotation concentration methods was investigated to decrease its ash content. Finely disseminated inorganic constituents of asphaltite revealed the difficulty of operation. Ash content of asphaltite was reduced from 44.86% to 31.44% by gravity concentration method with a 75% combustible recovery. On the other hand, it was possible to reduce ash content to 24% by flotation with almost same combustible recovery. Combustion characterization of raw and impro...
Forced Response Prediction of Constrained and Unconstrained Structures Coupled Through Frictional Contacts Ciğeroğlu, Ender; Menq, Chia-Hsiang (ASME International, 2009-03-01) In this paper, a forced response prediction method for the analysis of constrained and unconstrained structures coupled through frictional contacts is presented. This type of frictional contact problem arises in vibration damping of turbine blades, in which dampers and blades constitute the unconstrained and constrained structures, respectively. The model of the unconstrained/free structure includes six rigid body modes and several elastic modes, the number of which depends on the excitation frequency. In o...
Determination of two and three phase relative permeabilty values by using a pore network model Karaman, T; Demiral, BMR (Informa UK Limited, 2004-06-01) In this study, a Pore Network (PN) tool was developed in order to obtain two and three phase relative permeability values. It has been found that the observed results agree with published data. It has also been found that as contact angle increased, irreducible water saturation decreased, and oil relative permeability increased for two phase oil-water imbibition simulations. During the three phase displacement simulation by pore network simulation it was observed that water and gas relative permeabilities a...
