چکیده
Abstract The oil-based mud is preferred to drill highly technical and challenging formations due its superior performance. However, the inadequate chemical thermal stability of conventional additives have greatly influenced performance at high-temperature conditions. Therefore, it critical design an with that withstand improve nanoparticles emerged as alternative can significantly enhance rheological filtration characteristics In this research study, a novel formulation OBM enhanced GNP formulated, conditions investigated. An extensive experimental study has been performed effect graphene nanoplatelets on properties along flow behaviour, viscoelastic properties, electrical barite sagging high temperatures. are characterised ascertain their purity morphology. result shows exhibited efficient improved mud. plastic viscosity yield point by 11% 42%, concentration 0.3 ppb. Similarly, gel strength tendency 14% 2%, respectively. loss also decreased up 62% 46%, 0.5 ppb 100 120 °C. addition results in formation thin cake compared base sample. modelling recommends shear-thinning behaviour ( n < 1), which correlated Herschel–Bulkley model. Artificial Neural Network model developed predict based four input parameters (concentration nanoparticles, temperature, shear rate stress). demonstrate favourable impact nanoplatelets, even small concatenation, high-temperature.
