“…The laponite crystals are disk-shaped nanoparticles with a diameter of about 20 nm (Jatav and Joshi 2014;Mongondry et al 2005) and a thickness of about 1 nm. According to literature research, the laponite is used to enhance the rheological performance (Liu et al 2017;Xiong et al 2019) and thermal stability of the drilling fluid (Huang et al 2019), and to inhibit the shale swelling (Huang et al 2018).…”

High-performance water-based drilling fluids (HPWBFs) are essential to wellbore stability in shale gas exploration and development. Laponite is a synthetic hectorite clay composed of disk-shaped nanoparticles. This paper analyzed the application potential of laponite in HPWBFs by evaluating its shale inhibition, plugging and lubrication performances. Shale inhibition performance was studied by linear swelling test and shale recovery test. Plugging performance was analyzed by nitrogen adsorption experiment and scanning electron microscope (SEM) observation. Extreme pressure lubricity test was used to evaluate the lubrication property. Experimental results show that laponite has good shale inhibition property, which is better than commonly used shale inhibitors, such as polyamine and KCl. Laponite can effectively plug shale pores. It considerably decreases the surface area and pore volume of shale, and SEM results show that it can reduce the porosity of shale and form a seamless nanofilm. Laponite is beneficial to increase lubricating property of drilling fluid by enhancing the drill pipes/wellbore interface smoothness and isolating the direct contact between wellbore and drill string. Besides, laponite can reduce the fluid loss volume. According to mechanism analysis, the good performance of laponite nanoparticles is mainly attributed to the disk-like nanostructure and the charged surfaces.

“…The static shear force was also enough, although the shear force decreased a little at 150 °C. Nanoscale laponite was an excellent pattern adjusting agent and could decrease the fluid loss and improve the high-temperature resistance of drilling fluids. , These nanoparticles could enhance the shear dilution performance of drilling fluids, beneficial for carrying cuttings and increasing the drilling rate.…”

With increasing intensified environmental pressure and a complex drilling environment, developing high-performance fluid loss additives with environmental acceptability is becoming a research focus. Through chemical cross-linking between starch, polyphenols, and lignosulfonate, a polymer SPL was facilely synthesized and it showed good filtration performance in bentonite–water-based drilling fluids (BT-WBDFs). The BT-WBDFs containing 2.0 wt % SPL polymer had a filtration volume of 7.0 mL/30 min at 150 °C. Moreover, SPL can resist the effect of 0.75 wt % CaCl2 and 7.5 wt % NaCl at 150 °C. The polymer SPL contributed to stable bentonite dispersion and kept enough viscosity of BT-WBDFs at high temperatures. The well-dispersed bentonite and SPL formed a thin and compact filter cake, providing effective plugging and shielding effects during the filtration process. Furthermore, a WBDF based on SPL as the main fluid loss additive was prepared and it displayed excellent high-temperature resistance, rheological property, inhibition, and environmentally friendly performance. This set WBDF has promising guidance on the design of high-performance drilling fluids with excellent environmental protection property.

Fluid homogeneity and stability are of high importance as they greatly affect the fluid performance in drilling operations. Solid settlement or solid sag is a severe issue that occurs in weighted drilling muds, especially at elevated temperatures, where the weight material tends to settle down causing well control problems. This study evaluates the effectiveness of a synthetic clay (laponite) to prevent the static and dynamic sag tendency of barite-weighted drilling fluid for elevatedtemperature drilling applications. Several high-density mud samples were prepared by varying the concentration of the synthetic clay. The sag tendency of the fluid samples was evaluated in the lab using dynamic and static sag tests, and the optimal concentration was determined. The impact of synthetic clay on the density, pH, and rheological properties was also studied. Moreover, the filtration properties of the developed formulation were measured using high-pressure high-temperature filtration experiments. The synthetic clay was found to be effective in reducing the static and dynamic sag tendency of barite-weighted water-based drilling fluids. 0.75 lb/bbl of laponite was adequate to eliminate solid sag at a temperature up to 250 F. This amount of laponite slightly increased the plastic viscosity by 8%, while an increase of 42% and 43−115% in the yield point and gel strength, respectively, was observed. A significant enhancement in the filtration performance was observed; the filter cake thickness and the filtrate volume were decreased by 15−20%. Additionally, the synthetic clay had an insignificant effect on the fluid density and pH.
