“…At high fluid loss, formation may be polluted and the drill pipe may be stuck. [33] The bentonite composite controls fluid loss well, which can reach at 9.3ml. This may due to the polar groups (amide groups, etc.)…”

Bentonite is the most important material used in oil and gas field drilling operations. However, the properties of natural bentonite cannot meet the requirements of bentonite for drilling. Therefore, researchers pay much attention to the modification of bentonite. The hydroxyethyl cellulose-acrylamide graft polymer was synthesized by microwave assisted, and the bentonite composite based on the graft polymer was prepared. FTIR, XRD and SEM results show that the polymer exists between the layers and the surface of the bentonite. Research on the bentonite composite showed that the yield point and filtration properties of bentonite composite are higher than natural bentonite at 90 to 150 celsius. The composite yield point / plastic viscosity ratio is more than 0.6 and the minimum fluid loss is only 9.3ml, which can meet the requirements of drilling-grade bentonite. This material has the potential to be a candidate for drilling applications.

Rheological and filtration properties of drilling fluid contribute a vital role in successful drilling operations. Rheological parameters such as apparent viscosity (AV), plastic viscosity (PV), yield point (YP) and gel strength of drilling fluids are very essential for hydraulic calculations and lifting of drill cuttings during the drilling operation. Control of filtration loss volume is also very important for cost effective and successful drilling operations. Therefore, the main goal of this research is to improve the rheological and filtration properties of Grewia Optiva fibre powder (GOFP) by using 30–50 nm size of silica nano particles (SNP) in water-based drilling fluid. The experimental outcomes revealed that after hot rolling of mud samples at 100 °C for 16 h, the low pressure-low temperature (LPLT) and high pressure-high temperature (HPHT) filtration loss of GOFP additives was improved, after the addition of SNP on it. The mixture of 5% GOFP + 4% SNP has reduced the LPLT and HPHT filtration loss of drilling fluid by 74.03 and 78.12%, respectively, as compared to base mud. Thus, it was concluded that after the addition of 0.4% SNP, the LPLT and HPHT filtration control ability of GOFP additive in WBM were increased by 17.6 and 15%, respectively. The rheological parameters such as AV, PV, YP and gelation of drilling fluids were also improved by the addition of GOFP + SNP mixture in the base mud. Therefore, the implementation of GOFP + SNP mixture in water-based mud showed auspicious results which reaffirm the feasibility of using them in the successful drilling operations.

“…Unfortunately, the average size of dispersed particles in that slurry was mainly over 1 micron, making the suspension poorly stable since the product began to separate after 2 weeks. More recently, several efforts have been done in order to develop and improve the properties of polymer slurries by reducing the particle size [16][17][18][19][20] , producing mostly submicron particle-based slurries. In the case of PS, Yamamoto and Takahashi synthesized a slurry made of polystyrene-silica core-shell particles and silica hollow particles, where the N-vinylacetamide acts as stabilizer for the polymer dispersion 17 .…”

“…Nevertheless, most of those procedures were focused on the production of nanoparticles, not paying attention to the final polymer suspension stability 21,22 . Furthermore, when the final liquid dispersions were obtained, they were prepared by drying and re-dispersing the polymer nanoparticles in another solvent, obtaining products with very low concentration 19 . Unlike microparticle slurries, nanoparticle-based ones can potentially keep much larger stability over time, since nanoparticle aggregation and deposition issues can be avoided or, at least, significantly reduced.…”

Slurries with low viscosity and polystyrene (PS) nanoparticles concentration up to 52 wt.% have been synthesized in one-step process with no waste generation, by suspension polymerization and optimizing the concentration of dispersants (sodium dodecylsulfate, SDS, and the cosurfactant, CS). The CS was manufactured in situ from tetraethyl orthosilicate (TEOS) and vinyltriethoxysilane (VTES). The incorporation of the CS on the PS polymer was confirmed by FT-IR, EDS and TGA; observing the functionalization of PS nanoparticles with SiOH. Morphology and particle size of the dispersed solid, together with viscosity and stability of the polystyrene slurries (PSSs) were analyzed, finding an abrupt reduction of the viscosity for PSSs by combining SDS and CS. Addition of SDS and CS (3.0 and 1.5 wt.%, respectively) allowed to produce PSSs with improved stability (ζ = -48.5 mV after one year), low viscosity (20.5 mPa•s at 25 ºC) and Newtonian behavior, containing up to 40.0 wt.% of single-spherical PS nanoparticles (< 100 nm).
