This study successfully developed a novel water-based completion fluid with enhanced properties. The system, incorporating nano clay (1.0%–3.0%) along additives like polyanionic cellulose, pre-gelatinized starch, polyethylene glycol 200, sodium formate, and chloride, was compared to conventional hydroxyethyl cellulose-based fluid. Viscosity filtration properties were analyzed using viscometer filter press. core flooding test Berea sandstone at an overburden pressure of 1000 psi conducted understand the formation damage potential optimized system. zeta analysis indicated better PAC-based colloidal system stability (−22.2 mV) HEC-based (−4.7 mV). HPHT 90 °C 500 demonstrated lower loss (9 ml), highlighting clay's effectiveness in control. higher surface area volume ratio & its capability fit between other particles, obstructing flow through them, assist return permeability value 97.3% for tests on revealed good control property Moreover, it also observed that enhances geomechanical rock samples, indicating borehole
