In this study, the effect of brine composition on oil recovery by waterflooding was experimentally studied. Different compositions of brine were injected in to packed one-dimensional unconsolidated limestone with Garzan crude oil (26 degrees API) and distilled water. Ten different brine compositions, three brine mixtures are prepared and distilled water was used for injection throughout the study. The highest recovery 18.8% higher than distilled water injection) considering all the experiments was obtained by the injection of 2% KCl + 2% NaCl brine mixture.


Effect of pressure on combustion kinetics of heavy oils
Bağcı, Ali Suat (Informa UK Limited, 2005-07-01)
In this study, 16 experiments were conducted to study the effects of pressure on crude oil oxidation in limestone medium. Karakus (29 degrees API), Beykan (32 degrees API), Bati Raman (12 degrees API), Camurlu ( 12 degrees API), Adiyaman (26 degrees API), Garzan (28 degrees API) and Raman (18 degrees API) crude oil from Turkish oil fields were used. The mixture of limestone and the crude oil was subjected to a controlled heating schedule under a constant flow rate of air. The produced gas was analyzed for i...
Effect of different clay concentrations on crude oil combustion kinetics by thermogravimetry
Kök, Mustafa Verşan (2010-03-01)
The objective of this research was to investigate the effect of different clay composition and concentrations on the thermal behaviour and kinetics of heavy crude oil in limestone matrix by thermogravimetry (TG/DTG). In TG/DTG experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixture known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Addition of clay to porous matrix significantly affected the react...
Effect of Polymers on the Rheological Properties of KCl Polymer Type Drilling Fluid
Kök, Mustafa Verşan (2005-05-01)
In the course of this research, the effect of two polymers (xanthan gum and polyanionic cellulose) on the rheological properties of KCl/polymer type drilling fluids was investigated. Non-Newtonian drilling fluids are conventionally characterized by rheological models (Bingham Plastic, Power Law, Casson, Herchel-Bulkley and Robertson-Stiff). In this research, forty-five KCl/polymer data sets of varying compositions are prepared. Polymer addition to the system has affected the model and caused a variation of ...
Effect of inlet pressure on crude oil combustion -laboratory approach-
Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2021-03-01)
In this research, the effect of inlet pressure on combustion behavior of medium and light crude oils was analyzed with TGA and DSC experiments. The ramped temperature combustion experiments were performed at constant heating rates under air atmosphere. TGA curves revealed three main reaction regions known as low temperature oxidation (LTO), fuel deposition (FD), and high temperature oxidation (HTO). In DSC curves, at the early stage of the heating, distillation region was also observed in addition to LTO an...
Effect of bentonite composition on the HP, HT rheological properties of water-based drilling fluids
Kuru, E; Demirci, S; Ozturk, MY (1998-12-01)
In this study, effects of six bentonites on the viscosity and filtration loss characteristics of water-based drilling fluids have been investigated. Rheological properties of the drilling fluids prepared by API standards were determined by using high temperature (0-100 degrees C) rotational viscometer. The filtration losses of these drilling fluids were measured using high temperature (0-232 degrees C) and high pressure (0-2000 psi) filtration loss measurement equipment.
