“…The Rheological models estimation is crucial to feature drilling mud in dynamic conditions. The rheology models include Newtonian, Bingham plastic, Power law, Herschel-Bulkley, Sisko, Ellis, Casson, and Hyperbolic models [12,13]. The main objectives of the current work focus on formulation of smart water-based drilling fluids incorporated with green magnetite NPs and an industrial alkali waste (spent caustic) as pH controller.…”

Drilling fluids are one of the most significant components of drilling operations for proper functions including fluid loss reduction into the formation and outstanding rheological properties. The drilling fluids according to environmental regulations and governmental rules have to be friendly to the environment to lessen the negative effects on the environment and improve safety. In the current study, a cost-effective industrial alkali waste (spent caustic) was used as a pH controller along with the environmentally friendly uncoated and Chitosan-coated green magnetite nanoparticles (MNPs) in water-based drilling fluid systems. The study focuses on exploring the impact of the alkali waste compared to the conventional alkali (NaOH) on rheology and filtration loss properties. The flow models of the drilling fluid systems were examined. The results proved that the drilling fluid formulated with polymer-coated green MNPs and waste alkali exhibited higher rheological properties and lower mud cake thickness and filtration volume compared to the reference fluid, thus, the waste alkali could replace NaOH as a pH controller. The flow behavior of new fluids could be described precisely using the Herschel-Bulkley flow model. Whereas, the Bingham plastic flow model described the fluid systems incorporated with uncoated and polymer-coated green NPs and NaOH.

“…Some scholars have studied the effect of drilling fluid rheology on drill string vibration. Rashidi et al[10] developed the MATLAB optimization program, and used five classical rheological models and two four parameter models (Cross and Carreau models) extracted from Herschel Bulkley Extended (HBE) model to fit the experimental measured values. It is found that the Bingham, Cross, and HBE models have precisely matched the measurements in the viscometer and could be used to study the effect of drilling fluid rheology on drill string vibration.…”

The drilling mud shows strong non-Newtonian rheology due to mixing a large number of cuttings at well bottom during drilling, which has great influences on the vibration behavior of the drill string. To investigate this phenomenon, an axial-lateral-torsion coupling (ALTC) nonlinear dynamic model based on Hamilton's principle was established, taking into account the effect of drilling fluid viscous damping, Herschel-Bulkley non-Newtonian rheological (HBNR) damping, bit-rock interaction and drillstring-borehole contact. In the model, a Rayleigh damping matrix calculation method was proposed to describe the influence of drilling fluid on the damping of ALTC vibration, and the Newmark-β method was used to solved the nonlinear discrete equations of the system. The validity of the model was verified through the simulation data and the field measurement data. Using the nonlinear model, the effect of drilling fluid rheology on ALTC vibration response of rotary drill string was investigated. It was found that compared with viscous damping, HBNR damping can significantly suppress the axial, lateral and torsional vibration of drill string, maintain the stability of wellbore diameter and improve ROP. Both damping models indicate that lateral vibration signals are difficult to transmit to the wellhead, while axial vibration and torsional vibration signals can be observed near the wellhead. The results can provide a theoretically guidance for suppressing the drill string vibration and reducing the risk of premature failure of drill string.
