We developed high-performance low-solid benetonite-water-based drilling fluids using cellulose nanomaterials (CNs) from wood as multifunctional additives (i.e., rheological modifier, filtration control agent and thermal/salt tolerant agent) for commercial drilling operations in a wide range of formations, especially in gypsum layers and salt rocks. Work also incluced the use of modified CNs in polymer composites. The approaching era of sustainable development and rapid increase in global energy demand necessitate the development of high-performance drilling fluids with low-toxicity, sustainability, and in-situ rheology controllability for complicated formation excavation. Herein, smart waterbased drilling fluids (WDFs) with thermo-controllable rheological properties are developed using bentonite (BT) and dual-functionalized cellulose nanocrystals (fCNCs). The fCNCs are synthesized by surface grafting of poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) and poly (N-isopropylacrylamide) (PNIPAM) through free radical graft polymerization. The presence of PAMPS grafts with abundant amide and negatively charged sulfonate groups not only enable fCNCs to attach on the surface of BT platelets, creating BT/fCNC clusters; but also ensure the created BT/fCNC clusters to uniformly disperse through electrostatic repulsion. On the other hand, the introduction of thermo-responsive PNIPAM grafts induce the association of BT/fCNC clusters at elevated temperatures through enhanced hydrophobic attraction, resulting in promising thermo-thickening rheological performance of BT/fCNC-WDFs. Furthermore, the thermo-thickening rheological behavior can be maintained even after 10 heating/cooling cycles, albeit with a slight increase in the critical transition temperature. The developed BT/fCNC-WDFs with sustainability, in-situ rheology controllability, and good cyclability have great potential in smart drilling industry, making the exploration and production of oil and gas more safe, efficient and environmentally friendly. We have successfully developed a rapid and efficient method to isolate cellulose fibers from energy cane bagasse (ECB) using microwave-assisted NaOH / NaClO2 treatments. After microwave treatments, 88.9% delignification of ECB was achieved and the mean diameter of cellulose fibers with a yield of 34.2% decreased from 82 ± 24 μm (raw bagasse) to 9 ± 2 μm. Based on the XRD, FTIR, and NMR results, microwave irradiation and higher NaOH concentrations were conducive to the transformation of cellulose crystal structure from cellulose I to II, caused by the swelling of cellulose fibers and the rearrangement of cellulose chains. CNFs prepared by mechanical treatment from MD20 had much reduced diameter compared with that from MD10 (i.e., 8.05 nm vs 16.36 nm). The obtained CNF suspensions demonstrated solid-like viscoelastic properties owing to the formation of entangled networks. A small amount of CNF (0.5 wt%) can replace half of BT in WDFs, and their rheological properties were improved (exhibiting more significant shear-thinning and higher values in both viscosity and yield point) and filtration properties were maintained by the formation of three-dimensional network structure by CNFs.

Performance of hardened oil well cement (OWC) is largely determined by the rheologicalproperties of the cement slurries. This work was carried out to investigate the effect of water-to-cement ratio (WCR) and cellulose nanoparticles (CNPs), including cellulose nanofibers (CNFs) and cellulose nanocrystals (CNCs), on rheology performance of OWC-based slurries using a Couette rotational viscometer coupled with rheological models. The yield stress and viscosity of neat OWC slurries showed a decreasing trend with the increase of WCRs. The suspension became increasingly unstable with the increase of WCRs. The properties of CNPs, including rheological behaviors, surface properties and morphology, determine the rheological performance of CNP-OWC slurries. In comparison with CNC-OWC slurries, the gel strength, yield stress and viscosity of CNF-OWC slurries were higher as CNFs were more likely to form an entangled network. The gel strength, yield stress and viscosity of CNP-OWC slurries increased with reduced CNF size through regrinding and the proportion of CNFs in the mixture of CNFs and CNCs, respectively. High performance nanocomposites with good interfacial miscibility and phase separated morphologyhave received a lot of attention. In this work, cellulose nanocrystals (CNCs) were first grafted with hydrophobic poly(methyl methacrylate) (PMMA) chains to produce modified CNCs (PMCNCs) with increased thermal stability. Such surface-tailored CNCs effectively influenced the phase morphology and improved the mechanical properties of poly(butyl acrylate-co-MMA) (PBA-co-PMMA) nanocomposites. Morphological analysis indicated the presence of microphase separation in PMCNCs/PBA-co-PMMA nanocomposites with PBA as the soft domain and PMMA as well as CNCs as the hard domain. The nanocomposites with 10 wt% PMCNCs/PBA-co-PMMA showed increases in Young's modulus of more than 20-fold and in tensile strength of about 3-fold compared to those of the unmodified PBA-co-PMMA copolymer. Therefore, the PMCNCs played a crucial role in controlling the interfacial miscibility and tuning the phase morphology of the nanocomposites. It is also essential to understand the role played by microphase separation in achieving nano-scaled morphological control and in fine-tuning the resultant composite properties.

The forthcoming era of sustainable development demands the utilization of naturally abundant, sustainable, biodegradable, and environmentally friendly resources for a wide variety of applications. Herein, we report the isolation of chitin nanocrystals (ChNCs) from speckled swimming crab shell waste and their novel utilization as rheology modifiers in bentonitewater-based drilling fluids (BT-WDFs). The positively charged functional groups on the surface of ChNCs enable them to attach to the negatively charged face surfaces of BT by electrostatic attraction, leading to a notable improvement in the rheological property that is responsible for the ability of drilling fluids to carry away drill cuttings. Moreover, owing to the reversible protonation and deprotonation of ChNCs and BT platelets, ChNC/BT-WDFs can form distinctive dispersion states and nanostructured surface interactions under different pH conditions. As a result, ChNC/BT-WDFs exhibit interesting pH responsive rheological and filtration performance, especially when the pH is changed from neutral to acidic. Finally, the combined use of ChNCs with a conventional filtration control agent - polyanionic cellulose (PAC) leads to remarkable improvement in both rheological and filtration performance of BT-WDFs. It is expected that these observations not only enrich the high-value utilization of crab shell waste but also advance the development of smart nanofluids with pH-responsiveness for various applications. Super-fine grinding and homogenization treatments were carried out to produce lignocellulosic nanomaterial (LCNM) from biomass of pine bark (BLCNM) and tobacco leaf stem (TLCNM) in thiswork. Basic material characterizations and thermal analysis were done to establish morphology, surfacechemical structure, and thermal decomposition kinetic behavior of the materials. Both BLCNMand TLCNM showed a mixture of nanosized fibers and free lignin nanoparticles. The diametersof nanofibers and free lignin particles are, respectively, 12±6 nm and 13±4 nm from bark; and4±1 nm and 8±4 nm from tobacco leaf stems. TLCNM had a relatively lower onset degradation temperature, higher thermal degradation degree, lower temperature interval and lower residueweight compared with those of BLCNM. The apparent activation energy (AAE) values varied from229 to 239 KJ/mol for BLCNM and from 229 to 233 KJ/mol for TLCNM in the conversion range of0.1-0.6 via the model-free kinetic methods. Two LCNMs showed a similar overall AAE values. The materials are being used for future fluid formulations.
