A mathematical model is introduced estimating the frictional pressure losses of Newtonian fluids flowing through a concentric annulus. A computer code is developed for the proposed model. Also, extensive experiments with water have been conducted at Middle East Technical University, Petroleum and Natural Gas Engineering Department Flow Loop and recorded pressure drop within the test section for various flow rates. The performance of the proposed model is compared with computational fluid dynamics (CFD) software simulated annulus flow section and various criteria such as crittendon, hydraulic diameter and slot flow approximation as well as experimental data. The results showed that the proposed model and experimental results are in good agreement for almost all cases when compared with the other criteria and CFD software. Also, the proposed model could estimate the frictional pressure losses for both laminar and turbulent flow regimes within an error range of +/- 10%.

Comparative study of yield-power law drilling fluids flowing through annulus
Ozbayoglu, M. E.; Omurlu, C. (Informa UK Limited, 2007-01-01)
An exact solution for calculating the frictional pressure losses of yield-power law (YPL) fluids flowing through concentric annulus is proposed. A solution methodology is presented for determining the friction factor for laminar and nonlaminar flow regimes. The performance of the proposed model is compared to widely used models as well as the experimental results of 10 different mud samples obtained from the literature. The results showed that the proposed model could estimate the frictional pressure losses...
A computational procedure for estimating residual stresses and secondary plastic flow limits in nonlinearly strain hardening rotating shafts
Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2005-03-01)
A computational procedure to estimate the residual stress distributions and the limit angular speeds for avoiding secondary plastic deformation in nonlinearly strain hardening rotating elastic-plastic shafts is given. The model is based on von Mises yield condition, J(2) deformation theory and a Swift-type hardening law. The boundary value problem for the governing nonlinear differential equation is solved by a shooting method using Newton iterations with numerically approximated tangent. Solid as well as h...
The effect of fractures on the steam-assisted gravity drainage process
Bağcı, Ali Suat (American Chemical Society (ACS), 2004-11-01)
This study presents an experimental investigation of the effect of fractures and well configurations on the steam-assisted gravity drainage (SAGD) process in a three-dimensional model, using 12.4degreesAPI gravity crude oil. A total of eight runs were conducted, using a 30 cm x 30 cm x 10 cm rectangular-shaped box model. Temperature distributions were observed using 25 thermocouples. Three different well configurations were investigated-a horizontal injection and production well pair, a vertical injection-v...
A stochastic approach in reserve estimation
Kök, Mustafa Verşan (Informa UK Limited, 2006-12-01)
Geostatistics and more especially stochastic modeling of reservoir heterogeneities are being increasingly considered by reservoir analysts and engineers for their potential in generating more accurate reservoir models together with usable measures of spatial uncertainty. Geostatistics provides a probabilistic framework and a toolbox for data analysis with an early integration of information. The uncertainty about the spatial distribution of critical reservoir parameters is modeled and transferred all the wa...
Modelling of two-phase flow through concentric annuli
Ozbayoglu, M. E.; Omurlu, C. (Informa UK Limited, 2007-01-01)
A mathematical model is introduced in order to predict the flow characteristics of multiphase flow through an annulus. Flow patterns and frictional pressure losses estimated using the proposed model are compared with the experimental data of a wide range of liquid and gas flow rates recorded at a flow loop consisting of numerous circular pipes and annulus. The results showed that the model predictions for flow patterns and frictional pressure losses are reasonably accurate. Moreover, it is observed that geo...
