Accurate estimation of the frictional pressure losses for non-Newtonian drilling fluids inside annulus is quite important to determine pump rates and select mud pump systems during drilling operations. The purpose of this study is to estimate frictional pressure loss and velocity profile of non-Newtonian drilling fluids in both concentric and eccentric annuli using an Eulerian-Eulerian computational fluid dynamics (CFD) model. An extensive experimental program was performed in METU-PETE Flow Loop using two non-Newtonian drilling fluids including different concentrations of xanthan biopolimer, starch, KCl and soda ash, weighted with barite for different flow rates and frictional pressure losses were recorded during each test. This study aims to simulate non-Newtonian fluids flow through both horizontal concentric and eccentric annulus and to predict frictional pressure losses using an Eulerian-Eulerian computational fluid dynamics (CFD) model. Computational fluid dynamic simulations were performed to compare with experimental data gathered at the METU-PETE flow loop and previous studies as well as slot flow approximation for the annulus. Results show that the computational fluid dynamic model simulations are capable of estimating frictional pressure drop with an error of less than 10% in most cases, more accurately than the slot equation.

Computational Fluid Dynamics Modeling of Pipe Eccentricity Effect on Flow Characteristics of Newtonian and Non-Newtonian Fluids SORGUN, MEHMET (Informa UK Limited, 2011-01-01) The prediction of accurate drilling fluids behavior inside an annulus is especially important in drilling engineering during hydraulic program design. The flow characteristics of Newtonian and non-Newtonian fluids drastically change in the annuli when the inner pipe is eccentric. In this study, the fluid flow inside concentric, partially eccentric, and fully eccentric annuli are modeled using computational fluid dynamics. Computational fluid dynamics simulations are performed to investigate the effect of pi...
Estimation of Filter Cake Thickness for Water-based Drilling Fluids Kök, Mustafa Verşan (Informa UK Limited, 2010-01-01) It is obvious that estimation of filter cake thickness is one of the important parameters in drilling operations. In this study, dynamic filtration data was used to determine the filter cake thickness. Predictions were made through linear filtration cake model by using dynamic filtration experimental data. Linear filtration model can be used to approximate radial filtration model; only the thickness of the filter and filter cake is sufficiently smaller than the radius of the filter surface exposed to slurry...
Trajectory Estimation in Directional Drilling Using Bottom Hole Assembly Analysis Dogay, S.; Ozbayoglu, E.; Kök, Mustafa Verşan (Informa UK Limited, 2009-01-01) The aim of this study is to put together the basic concepts of mechanics on drill string which are related to directional drilling, thus finding a less complicated and more economical way for drilling directional wells. Slick bottom hole assembly, which has no stabilizers attached, and single stabilizer bottom hole assembly are analyzed through previously derived formulas gathered from the literature that are rearranged for this study. An actual directional well is re-drilled theoretically with a slick asse...
Modeling of CO2 storage in an oil reservoir Gumrah, F.; Dulger, M.; Gunaydin, D.; Senel, O. (Informa UK Limited, 2008-01-01) This study provides an overview for the carbon dioxide sequestration process in an oil reservoir by using the software CMG's GEM. Different scenarios are applied for the oil reservoir description. Firstly, a single layered reservoir is considered and simulation studies are performed, as this reservoir is homogeneous, heterogeneous and fractured. Secondly, a multi-layered reservoir is examined. In the second case, a heterogeneous system and a heterogeneous system composed of homogenous layers are selected. F...
The Application of Water-flood Technology for Different Oil Fields Kök, Mustafa Verşan (Informa UK Limited, 2011-01-01) Water-flooding is perhaps the most common method of secondary recovery, in which water is injected into the reservoir formation to displace residual oil. The water from injection wells physically sweeps the displaced oil to adjacent production wells. In this study, three different fields from different locations were studied for a possible water-flooding operation using software. Through the results obtained from the application, certain predictions were obtained about the water-flood performance of the oil...
