Effect of silica nano particles on the rheological and HTHP filtration properties of environment friendly additive in water-based drilling fluid

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