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 achieved and the optimum PHPA concentration for drag reduction purposes was estimated as 0.0020 (v/v). A friction factor is developed as a function of PHPA concentration and Reynolds number, and the results show that the pressure losses can be estimated with an error less than 15% by using the proposed friction factor.

Sensitivity Analysis of Major Drilling Parameters on Cuttings Transport during Drilling Highly-inclined Wells Ozbayoglu, E. M.; Miska, S. Z.; Takach, N.; Reed, T. (Informa UK Limited, 2009-01-01) 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,...
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...
Thermal Analysis of Crude oil lignite mixtures by Differential Scanning Calorimetry Kök, Mustafa Verşan (Elsevier BV, 1994-04-01) Thermal characterization of lignite, crude oils and their 10 and 20% mixtures were investigated by differential scanning calorimetry (d.s.c.). The calorific value of the lignite increased in mixtures depending on the crude oil type. In pyrolysis runs, temperature ranges where distillation and visbreaking occur were identified for the crude oils studied. The effect of heating rate was also studied, and higher reaction temperatures and higher heat flow rates were observed at d.s.c. peak thermograms with incre...
3-d model studies of alkaline flooding using horizontal wells Bağcı, Ali Suat (Informa UK Limited, 2004-07-02) In this study, the effect of sodium hydroxide (NaOH) solution for the improved oil recovery of Garzan (26degreesAP1) crude oil was investigated using two different laboratory models. The effect of injection rate on oil recovery was investigated using a one-dimensional unconsolidated limestone reservoir model. The effect of horizontal and vertical well configurations on oil recovery was also studied using a 3-D physical model and various well configurations. As previously studied, the interfacial tension mea...
