“…The impact of changing hole eccentricity has also not been extensively studied by these experimental methods. Several one-dimensional (across the wellbore) and two-dimensional (across cross-sectional flow area) numerical studies on cuttings transport with a variety of drilling fluids have been conducted (Guckes, 1975;Nguyen and Rahman, 1996;Ozbayoglu et al, 2005;Osunde and Kuru, 2006;Zaisha et al, 2012). However, the use of CFD provides an unparalleled opportunity of analysing multiphase flows in three dimensions.…”

The increasing global energy demand has pushed the oil industry towards developing more innovative and advanced methods of enhancing oil recovery even under unfavourable technical and environmental conditions. The severity of many operational problems affecting the drilling and production of oil and gas wells is worsened by inaccessibility; hence, remedial efforts must be implemented from afar. One of these problems is ensuring efficient removal of formation rock cuttings with a suitable fluid, whose rheology is often complicated. Furthermore, pressure losses along the annular geometry involved, and decreased Rates of Penetration (ROP) due to accumulated drill cuttings downhole, constitute significant portions of the total energy to be supplied. Thus, the application of sophisticated modelling techniques with credible elucidation of the phase distributions (solids, liquids and gas) and prevalent flow regimes becomes essential, if adequate and economic design of a drilling program is desired. The advent of Computational Fluid Dynamics (CFD) and the growth in the available computational power to support it have provided an unprecedented opportunity to simulate and understand complex real flows, especially when experimental methods become extremely demanding. The present study employs the tool of Computational Fluid Dynamics to simulate a two-phase solid-liquid flow in an annulus based on the analysis of cuttings concentration, pressure drop profiles, axial fluid, and solid velocities as a function of several drilling parameters: drill pipe eccentricity, inclination, drill pipe rotation, ROP and fluid rheology. Special emphasis is however, placed on the impact of changing hole eccentricity on cuttings transport efficiency. The suitability of the Eulerian-Eulerian (EE) multiphase tracking scheme in modelling systems of high volume fractions is fully utilised in this work. A non-Newtonian (power law) fluid model with well-described flow parameters is implemented, considering a uniform cuttings size distribution (3 mm). A commercial CFD software (ANSYS FLUENT TM 17.1) has been used; the descriptive and predictive potential of the CFD software has been confirmed on account of the reasonable agreement with previously published experimental data (a relative error of less than 11% is achieved), as illustrated by the corresponding sensitivity plots. This multi-parametric CFD analysis study of multiphase cutting transport during drilling applications has confirmed that fluid velocity, hole inclination and annular eccentricity are the most influential factors governing the cuttings transport efficiency.2

“…Researchers have demonstrated that particle transport is affected by many factors, such as drill pipe diameter, drill pipe rotation, drill pipe eccentricity, well inclination, and drilling fluid rheological properties (Capo, Yu, Miska, Takach, & Ahmed, 2006;Chen et al, 2007;Clark & Bickham, 1994;Espinosa-Paredes, Salazar-Mendoza, & Cazarez-Candia, 2007;Kelessidis & Bandelis, 2004;Ozbayoglu, Miska, Reed, & Takach, 2005;Ozbayoglu, Saasen, Sorgun, & Svanes, 2010;Ramadan, Skalle, Johansen, Svein, & Saasen, 2001;Sanchez, Azar, Bassal, & Martins, 1999;Tomren, Iyoho, & Azar, 1986). However, there remains a dearth of information on the effects of particle shape on the hole cleaning process in directional well drilling.…”

“…It has also been observed that when aerated fluids are used as drilling fluids in horizontal wells, the liquid phase has the main impact on the cuttings carrying process, rather than the gas phase (Vieira et al, 2002, Naganawa et al, 2002. Also, for foams, as the gas ratio is increased, the cuttings bed development is increased (Ozbayoglu et al, 2005). Eccentricity, wellbore geometry, wellbore inclination, cuttings properties, etc., also have some influences on cuttings transport in horizontal drilling.…”

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.
