“…Shale formations consist of consolidated clay minerals and contain native fractures and nano-pores. This results in their ultra-low permeability (van Oort 2003;Zhang et al 2013;Zhong et al 2011) and serious clay swelling when encountering water, a main factor causing hole collapse, wellbore weakening, and stuck pipes in drilling (Zhong et al 2015). The composition of clay minerals is a major factor contributing to swelling capability as some clay minerals are non-swelling.…”

Graphene oxide (GO) nano-sheets were synthesized using a modified Hummers' method from graphite powder. The Raman spectrum of GO displayed a D-band at 1359 cm -1 and a G-band at 1594 cm -1 . The I D /I G value of GO was calculated to be 0.97, suggesting the formation of new sp 2 clusters upon reduction. A method was designed to investigate the assembly of the GO/montmorillonite (MMT) composite. After the addition of GO, the typical peaks of montmorillonite in FT-IR spectra shifted, indicating the assembly between GO and MMT. The D-band and G-band reduced sharply in the GO/MMT composite. More importantly, the D-band (1344 cm -1 ) and G-band (1574 cm -1 ) shifted significantly and the I D / I G value of the GO/MMT composite was calculated to be 1.13, showing a change in the GO structure. In the addition of 0.04 wt% GO to MMT, the value of interlayer space (d) was up to 13.0 Å measured by XRD due to the insertion of GO into MMT. The evident increases in contents of carbon atoms (26.59%) and nitrogen atoms (3.44%) indicate that GO was successfully combined with MMT. The nano-pores and clay sheets were not observed in the SEM image of GO/clay, but obvious wrinkles, while flexible sheets were observed in the typical scanning electron microscopy images of GO. This further proves that GO was combining with clay. The TEM image shows that the GO nano-sheets were tiled on the surface of MMT sheets. This observation suggests that a stable assembly structure was formed between GO sheets and MMT sheets. The change in particle size of MMT with the addition of GO shows that interaction occurred between GO sheets and MMT sheets, which was further confirmed by the results of zeta potential. Adsorption and insertion were the main mechanisms to assemble GO and MMT.

“…The higher the absolute values of negative zeta potential, the bigger the double layer thickness of the shale particle. Higher negative zeta potential value is also indicative of swelling and dispersion of clay (Zhong et al 2011). The zeta potential values measured for the shale samples were *-24 mV for both Chattanooga and Pride Mountain shale.…”

Interaction of polymer-containing injected fluids with shale is a widely studied phenomenon, but much is still unknown about the interaction of charged polyacrylamides such as anionic and cationic polyacrylamides with shale. The nature of interaction of charged polyacrylamides with shale is not well understood, especially from the perspective of assessing the potential for polyacrylamides to cause formation damage. Zeta potential and rheological measurements were made for Chattanooga and Pride Mountain shales suspended in polyacrylamide solutions with and without inorganic salts and tetramethyl ammonium chloride (TMAC). The change in zeta potential and viscosity with time was recorded. The magnitude of decrease in the absolute value of zeta potential with time is indicative of adsorption of polymer on the surface of shale and serves as a measure of the extent of polymer interaction with shale. The salts that were used in this study are potassium chloride (KCl), sodium chloride (NaCl). This study quantified the interaction of anionic and cationic polyacrylamide with different North American shales. From the experimental results, it was determined that the polyacrylamides can interact strongly with shale, particularly the cationic polyacrylamide. The objective of this study was to determine the extent of interaction of anionic and cationic polyacrylamide with each shale sample in the presence of additives such as salts.

“…The other part was dried at 105 o C and ground to powder for XRD measurements, water adsorption test, SEM and TGA. The test procedure of zeta potential was reported previously and measured at room temperature using the Zetasizer 3000 electric potential and granularity meter (Malvern instrument, United Kingdom) [21]. The water adsorption test was as follows, modified MMT powders (1 g) was placed in a sealed glass desiccator with water in the bottom.…”

Abstract:In order to improve the inhibitive properties and high temperature resistance of shale inhibitor, cycloaliphatic amines were introduced as shale hydration inhibitors in water-based drilling fluids. Bulk hardness test, shale cuttings dispersion test, bentonite inhibition test and water adsorption test were carried out to characterize the inhibitive properties of the novel amines. Surface tension measurement, zeta potential measurement, XRD, contact angle test, SEM and TGA were performed to investigate the interaction between the cycloaliphatic amines and clay particles. The results indicated that cycloaliphatic amines exhibited superior inhibitive properties to the state of the art inhibitors. Moreover, the amines were high temperature resistant. The hydrophobic amine could intercalate into the clay gallery with monolayer orientation. The protonated ammonium ions neutralized the negatively charged surface. After adsorption, the hydrophobic segment covered the clay surface and provided a shell preventing the ingress of water.
