“…Nevertheless, as Young & Iskander [12] concluded, these approaches have exhibited various limitations and remained somewhat unsuccessful with regard to the dehydration of clay minerals. A recent advance was the introduction of water-based drilling fluids containing low molar masses of polyether amine compounds, as proposed by Klein et al [13] , Patel et al [14] , and Qu et al [15] .…”

Polyamine (PA) is a novel inhibitor applied to water-based drilling fluid in order to reduce clay hydration. In this paper, water adsorption behavior on kaolinite and illite after PA adsorption (PA-kaolinite, PA-illite) was characterized by X-ray diffraction (XRD), diffuse reflectance infrared Fourier transform spectroscopy (DRIFT), and adsorption isotherms tests using water, benzene, and heptane. After PA adsorption, water adsorption on kaolinite was enhanced while water adsorption on illite was reduced. Water vapor adsorption affinity on kaolinite in an entire range was significantly increased due to H-bonds between the ammonium groups of PA and water molecules. As a result, kaolinite surface tension was increased. Water adsorption affinity on illite in the low relative humidity (RH) regimes was decreased after PA adsorption and illite surface tension decreased because fewer water molecules could adsorb on tetrahedral (SiO 4) of illite. Therefore, PA can be used as inhibitor while drilling shale formations mainly composed of illite, not kaolinite.

“…Numerous chemicals including inorganic salts, formates, organic amine compounds, polymers, silicates and polyglycerols have been used with different mechanisms such as hydration inhibition, reduction of pore pressure transmission, or cuttings encapsulation (Galindo et al, 2015;Patel et al, 2007;Reid et al, 1995;Van Oort, 2003;Xuan et al, 2013;Zhang et al, 2001). Based on these chemical inhibitors, several inhibitive water-based drilling fluids have been established and utilized in the field (Donham and Young, 2009;Patel and Gomez, 2013;Stamatakis et al, 1995;Young and Ramses, 2006). Nevertheless, it is not completely successful for these fluids to inhibit the hydration and dispersion of reactive shales with various performance limitations (Patel et al, 2002).…”

Dendrimers have been paid increasing attention in the area of drilling fluid recently due to their unique structure and properties. The inhibitive properties of amine terminated polyamidoamine (PAMAM) dendrimers ranging from G0 to G5 were evaluated by relative inhibition rate, shale cuttings hot-rolling dispersion test and particle size distribution measurement respectively. Meanwhile the inhibitive capacity of the polymers under various pH value conditions was studied. The interaction between sodium bentonite and PAMAM dendrimers was characterized by zeta potential measurement and X-ray diffraction (XRD). The results indicated that, G0 and G5 are superior to polyether diamine, while G1, G2, G3 and G4 perform better than KCl. PAMAM dendrimers from G0 to G5 can decrease the zeta potential of clay particles from-39 mV to about-22.6 mV at natural pH values and reverse the charge when the pH value is adjusted to 9. When intercalated into the clay interlayer in aqueous solution, the candidate PAMAM dendrimers can form monolayer arrangement at lower concentrations and reduce the interlayer spacing of hydrated clay from 1.95 nm to 1.38-1.63 nm, which is the direct evidence of inhibiting shale hydration.
