“…There are generally two types of interaction designed to minimize clay hydration and dispersion. The first is preventing the water penetration between the clay layers and the second is hindering clay swelling as well as the migration of fines (Balaban et al, 2015). For G0, G1, G2 and G3 with low molecular mass, which behaved more like linear polymers, minimized the clay hydration by intercalating into the interlayer space and binding the adjacent layers together.…”

Abstract.1 In this work, stress-strain graphs of inverse emulsion fluids containing hydrophobically modified starch were plotted from measurements obtained with a coaxial rotating cylinder viscometer, and rheological models were applied. The Bingham model best fitted the experimental results. The correlations obtained by this model allowed calculating plastic viscosity values outside the shear rate sensitivity range of the viscometer and enabled better determination of the conditions for the fluid use.

“…This becomes the starting point for the evolution of some exotic salts (brines) as well as ammonium and aminebased chemistry for shale inhibition in high-performance water-based drilling fluids [7,8]. A vast number of amine and quaternary amine compounds have been introduced and applied in the field since the 1960s [9][10][11]. Based on the ''rule-based'' criteria for designing new and effective shale inhibitors, polyether amines have been introduced as shale inhibitors and believed to be the best available technology for shale inhibition in recent years [12,13].…”

In order to develop high-performance water-based drilling fluid with the aim of meeting the increasing requirement of drilling industry, highly inhibitive and high-temperature-resistant shale inhibitors are essential. In this study, 4, 4 0 -methylenebis-cyclohexanamine was introduced as a potential shale inhibitor. The inhibitive properties of the amine compound in comparison with currently available polyether diamine inhibitor were evaluated using bentonite inhibition test, shale cuttings hot-rolling dispersion test, linear swelling test, and pressure transmission test. The inhibitive mechanism was investigated with zeta potential measurement, X-ray diffraction analysis, and contact angle measurement. The results indicated that 4, 4 0 -methylenebis-cyclohexanamine can inhibit shale hydration and dispersion effectively, and prevent pressure transmission to a certain extent, performing better than that of polyether diamine. Furthermore, the new diamine provides reliable thermal stability as high as 220°C, preserving the benefits of high-temperature wells application. This novel diamine inhibits shale hydration and dispersion with the combination of chemical inhibition and physical plugging. The intercalation into the interlayer of clay with monolayer collapses the hydrated clay structure and expels the water molecules. After adsorption, clay surface became more hydrophobic, which prevents the imbibition of water. The variation of solubility separates the compound from the solution, which can plug the micro-pores of shale and prevent fluid invasion.
