This type of flow has been investigated in Walton and Bittleston [1991], Szabo and Hassager [1992], Nouri, Umur and Whitelaw [1993], Nouri and Whitelaw [1994], Hussain and Sharif [2000], for either Bingham or Herschel-Bulkley viscoplastic fluids. The two main objectives of these investigations were as follows: (1) The description of the unyielded regions.…”

“…Analytical solutions for power-law and yield-pseudoplastic fluids, but not for Herschel-Bulkley fluids, in concentric annuli have been presented by Gucuyener and Mehmetoglu (1992), David and Filip (1995) and Filip and David (2003). Analytical and numerical codes covering laminar flow of non-Newtonian fluids in both concentric and eccentric annuli have been presented by Haciislamoglu and Langlinais (1990), Walton and Bittleston (1991), Szabo and Hassager (1992), Yang and Chukwu (1995), Hussain and Sharif (1997), Siginer and Bakhtiyarov (1998), Meuric et al (1998), Fang et al (1999 and Hussain and Sharif (2000), while Round and Yu (1993) have studied numerically laminar nonNewtonian flows in the entrance of a concentric annuli. Fordham et al (1991) provided an analysis leading to a numerical code for solving the annulus situation as well as the case of slot approximation for laminar flow, together with some experimental data.…”

An integrated approach is presented for the flow of Herschel-Bulkley fluids in a concentric annulus, modelled as a slot, covering the full range of flow types, laminar, transitional, and turbulent flows. Prior analytical solutions for laminar flow are utilized. Turbulent flow solutions are developed using the Metzner-Reed Reynolds number after determining the local power law parameters as functions of flow geometry and the Herschel-Bulkley rheological parameters. The friction factor is estimated by modifying the pipe flow equation. Transitional flow is solved introducing transitional Reynolds numbers which are functions of the local power law index. Thus, an integrated, complete and consistent set, combining analytical, semi-analytical and empirical equations, is provided which describe fully the flow of Herschel-Bulkley fluids in concentric annuli, modelled as a slot. The comparison with experimental and simulator data from various sources shows very good agreement over the entire range of flow types.On présente une méthode intégrée pour l'écoulement des fluides d'Herschel-Bulkley dans un espace annulaire concentrique représenté par une fente, couvrant la gamme complète des types d'écoulement,à savoir laminaire, en transition et turbulent. Des solutions analytiques antérieures sont utilisées pour l'écoulement laminaire. Des solutions d'écoulement turbulent sontélaboréesà l'aide du nombre de Reynolds de Metzner-Reed après avoir déterminé les paramètres de loi de puissance locaux en fonction de la géométrie de l'écoulement et des paramètres rhéologiques d'Herschel-Bulkley. Le facteur de friction est estimé en modifiant l'équation d'écoulement dans un tube. L'écoulement en transition est résolu en introduisant les nombres de Reynolds exprimés en fonction de l'indice de loi de puissance local. Ainsi, un ensemble intégré, complet et consistant, combinant deséquations analytiques, semi-analytiques et empiriques, est fourni, qui décrit entièrement l'écoulement des fluides d'Herschel-Bulkley dans des espaces annulaires concentriques représentés par des fentes. La comparaison avec les données expérimentales et les données de simulateurs de diverses sources montre un très bon accord pour la gamme complète des types d'écoulement.

“…He solved semianalytically the governing fluid flow differential equations. Later on, other investigators [11,14,15] improved the laminar fluid flow with the help of analytical, semi-analytical and numerical methods in addition to the laboratory experiments. No analytical solution for turbulent flow exist as unlike laminar flow it does not follow any specific streamlines and therefore analytical solutions cannot be developed for a turbulent flow.…”

Coil tubing (CT) technology has been in use in the oil and gas industry since the 1990s. Since then, the applications of CT have expanded rapidly. Coiled tube drilling can offer more efficient and faster drilling operations resulting in lower operational costs.Micro-borehole CT drilling (CTD) has been used in oil and gas applications and is very attractive as a method for minerals exploration drilling due to the faster drilling i.e. high rate of penetration (ROP) that can be achieved resulting in reduced drilling costs. Due to the narrow annulus space there is a certain degree of uncertainty with regards to cuttings transport.In this paper we review the fluid flow and cutting transport models available for conventional drilling. Different aspects of fluid flow in micro-borehole CT will be addressed and discussed. The discussion illustrates the important parameters, including fluid properties, cuttings properties, fluid hydraulics and annular geometry affecting cutting transports in micro-borehole CT drilling in oil and gas as well as mineral exploration.
