In this study, a layered cuttings transport model is developed for high-angle and horizontal wells, which can be used for incompressible non-Newtonian fluids as well as compressible non-Newtonian fluids (i.e., foams). The effects of major drilling parameters, such as flow rate, rate of penetration, fluid density, viscosity, gas ratio, cuttings size, cuttings density, wellbore inclination and eccentricity of the drillsting on cuttings transport efficiency are analyzed. The major findings from this study are, the dominating parameter on wellbore cleaning is the flow rate, and, as the viscosity of the fluid is increased, the thickness of the cuttings bed developed in the wellbore is significantly increasing. Also, cuttings properties, fluid density, wellbore inclination and eccentricity have some influence on cuttings transport.

Modeling of underground gas storage in a depleted gas field Gumrah, F; Izgec, O; Gokcesu, U; Bağcı, Ali Suat (Informa UK Limited, 2005-07-15) It is possible to predict the behavior of fluids in permeable and porous medium under different operating conditions by using reservoir models. Since geological data and reservoir properties can be defined most accurately by reservoir models, it has been accepted as a reliable prediction tool among reservoir engineers. In this study, a gas reservoir has been modeled with IMEX Module of CMG Reservoir Simulator. Rock properties, gas composition and certain production data were entered to the model as input da...
Empirical correlations for estimating filtrate volume of water based drilling fluids Ozbayoglu, Evren; Gunes, Cagri; Apak, Esat C.; Kök, Mustafa Verşan; Iscan, A. Gurkan (Informa UK Limited, 2005-03-01) Standard American Petroleum Institute (API) filter press is generally used for identifying the filtrate volume of drilling fluids and works only at very low pressures. In fact, during a drilling operation, at downhole conditions, the pressures encountered are significantly higher than what is used during standard API filter press tests. A relationship between the well-known fluid properties and the filtrate volume test is developed. In this study, experiments have been conducted for different water-clay mix...
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...
Determination of Rheological Models for Drilling Fluids (A Statistical Approach) Kök, Mustafa Verşan (Informa UK Limited, 2004-01-16) A rheological model conventionally characterizes non-Newtonian drilling fluids. Parameters of the rheological models are estimated by explicitly solving the required number of equations simultaneously. Rheological models are stochastic and this study considers only the deterministic part of the model. Observed data is accepted as arising from randomness due to the system. A nonlinear least squares method is applied to readings of 6 standard Fann viscometer speeds in order to estimate the models' parameters....
PHPA as a Frictional Pressure Loss Reducer and Its Pressure Loss Estimation Ozbayoglu, M. E.; Ercan, C. (Informa UK Limited, 2010-01-01) This article analyzes the performance of a liquid polymer emulsion containing partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer as a circulating system pressure loss (drag) reducer. Straight cylindrical pipe flow experiments were performed at different concentrations of solutions for measuring frictional pressure losses. Comparison of measured and theoretical frictional pressure loss values showed that as the PHPA concentration increased, considerable drag reduction (as high as 60%) was achi...
