“…However, the increase of PVA percentage leads to a considerable increase of the viscosity (Fig 4). Such rheological behavior is explained by the different types of interactions susceptible to be established between PVA used as Binder and apatite particles which depend on the concentration of both of them [27]. In conclusion, a stirring time of 180 minutes is a medium duration that can be used when preparing the suspension to be used.…”

“…Foam with 2.0 wt% bentonite showed very good results of viscosity, that is, 245 mPa s, while foam without bentonite showed viscosity 190 mPa s at 90°C. The suspended bentonite clay particles showed a synergistic effect with guar, which enhanced the viscosity of base fluids by grafting on the polymer interface at higher temperature and strengthening the gas–liquid interface …”

Demand for foam fracturing fluids is ever‐increasing because of its nondamaging characteristics, less water requirement, combined with efficient proppant carrying capacity. The present study reported the synergistic effects of bentonite clay and polymer (guar) on rheology and stability of the foam prepared with surfactant (sodium dodecyl sulfate). Bentonite clay, which is never considered so far for improving quality of foam fracturing fluid, was found to provide improved foam rheology at reduced polymer concentration. Static and dynamic rheology with microscopic study showed the improvement of apparent viscosity, viscoelasticity, thermal stability, and morphology of foam on addition of bentonite clay. Addition of bentonite reduced the doses of polymer with similar proppant suspension capacity, which could be preferred over conventional gelled foam to reduce formation damage incurred by insoluble guar in the very low permeability unconventional reservoirs like shale gas, coal bed methane, or water‐sensitive formations. © 2017 Curtin University and John Wiley & Sons, Ltd.

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.
