“…The crucial response of CFD modelling will be a validation for the experimental data collated from the Nazarbayev University drilling laboratory. This is accompanied by a fairer comparison of data from previous research conducted by other authors [38]. Table 1 showcases rheological data considering only two properties that are a determinant of the safe transporting of cuttings [39] from the wellbore to the surface.…”

Several technical factors contribute to the flow of cuttings from the wellbore to the surface of the well, some of which are fundamentally due to the speed and inclination of the drill pipe at different positions (concentric and eccentric), the efficacy of the drilling mud considers plastic viscosity (PV) and yield point (YP), the weight of the cuttings, and the deviation of the well. Moreover, these overlaying cutting beds breed destruction in the drilling operation, some of which cause stuck pipes, reducing the rate of rotation and penetration. This current study, while it addresses the apropos of artificial intelligence (AI) with symmetry, employs a three-dimensional computational fluid dynamic (CFD) simulation model to validate an effective synthetic-based mud-drilling and to investigate the potency of the muds’ flow behaviours for transporting cuttings. Furthermore, the study examines the ratio effects of YP/PV to attain the safe transport of cuttings based on the turbulence of solid-particle suspension from the drilling fluid and the cuttings, and its velocity–pressure influence in a vertical well under a concentric and eccentric position of the drilling pipe. The resulting CFD analysis explains that the YP/PV of SBM and OBM, which generated the required capacity to suspend the cuttings to the surface, are symmetric to the experimental results and hence, the position of the drill pipe at the concentric position in vertical wells required a lower rotational speed. A computational study of the synthetic-based mud and its potency of not damaging the wellbore under an eccentric drill pipe position can be further examined.

“…The capacity of the drilling fluid to transport cuttings to the surface of the well is defined as the Cutting Carrying Index (CCI), as expressed in Equation 13. When the CCI is more than or equal to 1, the hole has been cleaned properly; nevertheless, when it is equal to or lower than 0.5, the hole has not been cleaned properly [6]. The following equation represents the CCI, an empirical connection based on actual data:…”

Drilling mud is a necessary component of drilling operations. There have been notable attempts to enhance the filtration and rheological properties and increase the cutting carrying capacity of water-based mud (WBM) using nanoparticles (NPs). This study investigates how varying Al2O3 concentrations affect the rheological properties and cutting carrying capacity of drilling fluids. In this study, different drilling muds were produced using bentonite (2.8g) without nanoparticle, 50% bentonite (1.4g) and 50% Al2O3(1.4) and 0% bentonite(0g) and 100% Al2O3 (2.8g). Testing and comparisons were done on the formed mud samples' physiochemical properties, rheology, filtration properties, and cutting carry index (CCI). The Power Law Model was used to define the rheological behavior of the manufactured mud samples, and results showed that all the mud samples were pseudoplastic fluids and remain a preference for drilling fluids because their flow behavior index (n) was less than 1. It was observed that the addition of Al2O3 is directly proportional to the plastic viscosity, apparent viscosity and yield point and inversely proportional to the gel strength of the drilling fluid. The study also shows that the addition of Al2O3 nanoparticle influences the cutting carrying index CCI as the calculated cutting carrying index gives a high cutting carrying index CCI which means that the hole cleaning potential of the drilling mud is good. The study shows that Al2O3 nanoparticles are feasible for use in drilling fluid formulation.

Proper and optimal selection of processing conditions in the production of nanofluids for drilling muds is critical. In this study, grey relational analysis (GRA) was employed as the computation analysis assisted by mathematical and graphical modeling to determine some optimal processing parameters to produce highly efficient biodegradable-polymer-based nanofluids for drilling muds. The multiple performance characteristics analyzed are consistency index (K), flow behavior index (n), yield point (YP), and plastic viscosity (YP). The obtained results revealed that 0.6 wt% starch, 1 wt% nanoparticles and 45 min. ultrasonic time are the optimal settings to be considered in the production of highly efficient nanofluids for drilling muds. The graphical modeling and ANOVA results also revealed that the experimental setups were influenced by some significant and unconsidered external factors in drilling fluids formulation. It is recommended that deeper study should be conducted to identify and employ some other unconsidered factors that may be responsible on the performance of drilling muds.
