Any improvement in drilling technology is critical for developing the oil and gas industry. The success of operations largely depends on fluid characteristics. Drilling fluids require enough viscosity to suspend particles transport them surface capability control loss into formation. Rheology filtration characteristics are crucial factors consider while ensuring effectiveness a operation. Graphene oxide (GO), xanthan gum (XG), low-viscosity carboxymethyl cellulose (CMC LV) being utilized this research produce high-performance, low-solid water-based (WDFs). Rheological behaviors GO/XG/CMC LV-WDF were investigated as function GO, XG, CMC LV at low concentrations (0.0–0.3% w/w) atmospheric conditions. According findings, GO improved rheological capabilities WDF. By adding 0.15 wt % shear stress could be doubled, especially high rate 1022 s–1. plastic expanded from 6 13 centipoise, 8.7 mL over 30 min was observed during API test, which would lower than suggested value (15.0 mL) mud. At same concentration XG LV, had more significant influence presence GO. Adding 0.3 increase 20.21 30.21 Pa In contrast, impact properties, acting agent by decreasing 21.4 14.2 min. addition solution may microstructure filter cake, resulting tree-root morphology. Indeed, GO/CMC solution, individual platelets bind together, form jellyfish shape, block micropores. incorporation helped develop compact cakes, excellent filtration. Five models employed match parameters quantitatively. Herschel–Bulkley model outperformed other simulating behavior. findings study can utilize provide low-cost, stable, environmentally compatible additives low-pressure, depleted, fractured reservoirs.
