“…XG is a common drilling fluid additive for controlling fluid loss, and viscosity improvement in the formulation of both oil-based and water-based drilling muds (Caenn and Chillingar, 1996;Navarrete et al, 2000). In response to environmental concerns, XG presents good properties for drilling muds application (Arabloo et al, 2012b). Brookey (1998) found XG biopolymer is the most effective viscosifier in stabilizing the aphrons in CGA based drilling fluids.…”

“…Therefore, selection of a suitable surfactant is important for the generation of aphrons with the desired rheological properties (Arabloo et al, 2012b). Natural surfactant used in this study successfully produced CGA-based drilling fluids like other commercial surfactants.…”

“…The high carrying capacity, the minimum amount of fluid placed in the formation, and the excellent fluid recovery after treatment are some of the advantages that CGA based fluids present when used during operations (Brookey, 1998;Growcock et al, 2006). The major implementation of rheological parameters for evaluating drilling fluid behavior are in solving problems of hydraulic calculations, suspension of cuttings and hole cleaning (Arabloo et al, 2012b). Shear rate and shear stress are the two basic measurements that are widely used in the petroleum industry and their relationship defines the type of fluid flow.…”

“…Thus, proper understanding and application of rheological principles is vital in evaluating drilling fluid behavior and in solving the problems of hole cleaning, hydraulic calculations, cutting transport (Arabloo and Pordel Shahri, 2014). In spite of the documented literature on the physico-chemical characteristics of CGA based drilling fluids (Arabloo and Pordel Shahri, 2014;Arabloo et al, 2012b;Bjorndalen and Kuru, 2008;Cardoso et al, 2010;Shivhare and Kuru, 2010;Spinelli et al, 2006Spinelli et al, , 2010, an interpretation of the rheological model of CGA based drilling fluids has not been fully addressed. While experimental work on the rheology of CGA based fluids is scant, there appears to be a virtual lack of thorough understanding of how the rheological properties are affected with system composition.…”

“…It has tolerance to changes of temperature, acidity, and alkalinity. From the viewpoint of environmental concerns, XG presents good properties for drilling mud applications [29]. Furthermore, a critical concentration of 1.25 to 1.5 lb/bbl must be present in the formulation of a drilling uid to provide adequate cutting transport capacity [26].…”

Abstract. Drilling uid is one of the most important and expensive aspects of any drilling process. Colloidal Gas Aphron (CGA) has been found e ective in controlling the ltration rate by bridging the pores of the reservoir rock; hence, reducing the formation damage. This work aims to synthesize the CGA in water based drilling uids to study the stability, rheology, ltration loss characteristics and formation damage properties of the resulting uid. Besides, an investigation on type of polymer, surfactant, and their concentration e ects on the characteristics of the uid, as well as optimum ratios of polymers in drilling uid was performed. Experimental results showed that Xanthan Gum (XG) provides more acceptable rheological properties (especially viscosity) in comparison to Guar Gum (GG) for preparing the base uid. Moreover, the Sodium Dodecyl Sulfate (SDS) produces more stable micro-bubbles than Hexadecyl Trimethyl Ammonium Bromide (HTAB) as a surfactant. Bubble size measurement to observe the e ect of polymer, surfactant type and concentration was performed. Through the experiments, the pH of the drilling uid was monitored which proved the CGA introduced the best performance around a pH of 9. Furthermore, a XG/GG ratio of 3:1 is suggested to reduce the cost while maintaining the uid properties.

Colloidal gas aphron (CGA) consists of spherical gas microbubbles with diameters ranging from 10–100 μm. Unlike regular foams, CGAs have a thin aqueous protective shell which makes them useful as a component of drilling fluid for practical applications. This paper reports on physicochemical properties of fluids containing CGAs. To this end, various laboratory tests of CGA generation, microscopic visualization, density measurement, API filtration loss, and rheological characterization with varying concentrations of biopolymer and surfactant were carried out. Three rheological models, namely the Bingham plastic, Casson, and Power‐law, were also employed to quantitatively describe the shear flow behaviour of CGA‐based fluids. Moreover, the CGAs performance as a filtrate‐reducing component was examined thorough a standard API filter press. The results of this study are helpful for better understanding the characteristics of CGA‐based fluids.
