“…The combination of smart polymers and nanosilica is an effective method for preventing free water intrusion into shale micronanopores during drilling and therefore assuring wellbore stability. Nano-SiO 2 has a strong potential for increasing the performance of low water-in-oil drilling fluids and high thermal stability with a decomposition temperature of 370 °C. − Another research demonstrates that the use of hybrid silicate, both organic and inorganic, as a film-forming agent significantly improved well stability in water-based drilling fluids . Another study revealed that silica NPs significantly improved shale inhibition with 96% shale recovery after hot rolling. , In comparison to their bulk form, the carbon-based nanostructures exhibit exceptional chemical, mechanical, physical, and electrical properties. , The carbon nanoparticles (CNPs) are being addressed to solve the technological and environmental difficulties associated with drilling.…”

Drilling fluids are an essential component of drilling operations in the oil and gas industry. Nanotechnology is being used to develop advanced drilling fluid additives. This study looked at the viability of synthesizing SiO 2 /g-C 3 N 4 hybrid extending the Stober process followed by its addition in different concentrations to water-based drilling fluids and studying impact on the rheological and fluid loss properties of the fluids. The synthesized hybrid was analyzed using XRD, SEM, TGA, and FTIR. Subsequently, it was used to develop the water-based drilling mud formulations and subjected to measurements in accordance with API standard practices. The studies were carried out at various SiO 2 /g-C 3 N 4 nanoparticle concentrations under before hot rolling (BHR) and after hot rolling (AHR) conditions. The outcomes demonstrated that the rheological and fluid loss properties were enhanced by the addition of SiO 2 /g-C 3 N 4 nanoparticles, as it worked in synergy with other additives. Additionally, it was discovered that the nanoparticles improved the drilling fluid thermal stability. The experimental findings indicate a significant influence of SiO 2 /g-C 3 N 4 nanoparticles on base fluid properties including rheology and fluid loss as the most remarkable, especially at higher temperatures. The significant improvements in yield point and 10 s gel strength were 55 and 42.8% under BHR and 216 and 140% under AHR conditions, respectively. Permeability plugging test (PPT) fluid loss was reduced by 69.6 and 87.2% under BHR and AHR conditions, respectively, when 0.5 lb/bbl nanoparticles were used in formulations. As a result, SiO 2 /g-C 3 N 4 nanomaterial has the potential to be used as drilling fluid additive in water-based drilling fluids.

Water-based drilling fluids are prone to contamination by high temperatures and high salt, resulting in a deteriorated filtration performance of the drilling fluids, posing a significant threat to the safety of drilling operations. This study utilized N,N-dimethylacrylamide (DMAA), 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), dimethyldiallylammonium chloride (DMDAAC), N-vinylpyrrolidone (NVP), and nanomaterials (nano-SiO 2 and nanolaponite) to prepare a polymer nanocomposite NP-3 as a filtratef reducer for drilling fluids. The thermal stability evaluation of the polymer solution revealed that the thermal degradation temperature order of the different structural units of the polymer is DMAA < AMPS ≈ DMDAAC < NVP, and the temperature resistance of NP-3 in the solution is 220 °C. Evaluation of drilling fluid performance demonstrated that 3.5 wt % NP-3 enabled the drilling fluid to resist contamination from 15 wt % NaCl at 230 °C, with an American Petroleum Institute (API) filtration loss and high-temperature and high-pressure (HTHP) filtration loss after hot rolling of 4.2 and 22.0 mL, respectively. At high temperatures, the degradation of the polymer composite releases nanoparticles, which enhance the density of the filter cake, allowing for adjustable and enhanced control of filtration performance of drilling fluids under high-temperature and high-salty conditions.
