Foam is a frequently used compressible fluid in drilling applications. Cuttings transport with foam has been a focus of interest for years. Few studies have been conducted on vertical well configuration and successfully applied. However, less is known about the performance of foam in highly inclined and horizontal wells. In this study, a layered model is developed for describing cuttings transport in horizontal wells. Due to the presence of a cuttings bed, generalized rheological model parameters for foam are modified analytically as a function of fluid properties and complex conduit geometry. Using these parameters, friction between the fluid and the wellbore, between the layers and slip between the cuttings and the fluid are determined. Model performance is examined using experimental data established at The University of Tulsa's low pressure-ambient temperature flow loop. Results showed that, developed model can predict developed cuttings bed thickness and pressure loss in the wellbore with an error of less than 20%. It has been observed that very high foam flow velocities are required in order to prevent a thick bed development in the wellbore. Also, low-viscosity fluids show better performance on preventing bed development inside the wellbore than high-viscosity fluids at the same flow rates.

Pressure Loss at the Bit While Drilling with Foam Ozbayoglu, E. M. (Informa UK Limited, 2009-01-01) Foam is one of the most frequently used drilling fluids at underbalanced drilling operations. As foam flows, due to the pressure drop, a volumetric expansion is observed, which causes the foam quality to increase in the same direction with flow. Flow of foams through circular pipes and annular geometries are well studied. Interestingly, although one of the major sources of pressure drop is at the bit, there have been few studies of this subject for foams. Many drilling parameters including hole cleaning cap...
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...
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,...
Rheological evaluation of polymers as drilling fluids Kök, Mustafa Verşan (Informa UK Limited, 2003-01-01) Polymers are recently found and still developing materials to overcome some drilling problems where conventional drilling fluids are not satisfactory enough. Simply, they are the best materials to use since they are non-toxic and do not cause serious environmental problems. In addition, polymeric drilling fluids may have properties such as better carrying capacity, less fluid loss, and thinner filtration cake depending on their composition and concentration. In this research, rheological parameters of two d...
Estimating Flow Patterns and Frictional Pressure Losses of Two-Phase Fluids in Horizontal Wellbores Using Artificial Neural Networks Ozbayoglu, E. M.; Ozbayoglu, M. A. (Informa UK Limited, 2009-01-01) Underbalanced drilling achieved by gasified fluids is a very commonly used technique in many petroleum-engineering applications. This study estimates the flow patterns and frictional pressure losses of two-phase fluids flowing through horizontal annular geometries using artificial neural networks rather than using conventional mechanistic models. Experimental data is collected from experiments conducted at METU-PETE Flow Loop as well as data from literature in order to train the artificial neural networks. ...
