“…However, we retain a system that exhibits both delayed gel collapse and double-yield behaviour. 5 Our formulation comprises a 3 M (CaCl 2 ) brine emulsion in Clairsol 370 mineral oil with VG69 hydrophobically modified clay (amine treated bentonite) 17 together with sufficient Versamul™ emulsifier and Versacoat™ HF dispersant to ensure a stable system. The emulsion is 50% by volume internal (brine) phase generated by high-shear mixing at 6000 rpm using a Silverson mixer (L4RT) fitted with a square hole high shear screen.…”

“…Several rheological studies conducted show that, at elevated temperature and pressure, the Herschel–Bulkley and Casson models fit the flow behavior of OBDFs fairly well. 19 , 72 − 75 The Casson rheological model accurately predicts the drilling fluid behavior across low and high shear rates. In addition, it is preferred to the Herschel–Bulkley rheological model due to the correction factor that is introduced to the yield stress and PV.…”

Organoclays (OCs), formed by surface modification of clay minerals using organic compounds, are typical additives for providing rheology for oil-based drilling fluids (OBDFs). There are different studies on the effect of OCs on the rheological properties of oil-based systems under high-pressure, high-temperature (HPHT) conditions, but finding new OCs as rheology control agents is attractive for drilling fluid engineers. This work reviews different OCs used in OBDFs, namely, organo-montmorillonite (OMMT), organo-sepiolite (OSEP), and organo-palygorskite (OPAL). Furthermore, the structure of OCs in OBDFs, their rheological properties, and the thermal stability of OCs were investigated. Besides, the role of fibrous and layered OCs in enhancing the rheological properties of OBDFs is illustrated. Finally, the synergistic use of different OCs to enhance the thermal stability and rheological properties of the OBDFs is presented. The study highlights research gaps and recommendations for research approaches and potential areas that need further investigation. The application of OCs in OBDFs is a wide field and has huge potential to be developed. The use of OCs in OBDFs will promote development in the oil and gas industry.

“…The variation of the shear stress 𝜏𝜏 as a function of the shear rate 𝛾𝛾̇ at different Aloe Vera concentrations from 2 wt% to 10 wt% added in sediments 40 wt% and 45 wt% is clearly made two behaviors separated by a critical shear rate: a Non-Newtonian behavior after a yield stress followed by a plastic behavior (Fig. 3) The experimental data was fitted by Casson model presented by the following equation [21,22]:…”

The phenomenon of siltation represents an enormous risk for the lifespan and safety of dams, and there are several methods for evacuating sediments, of which the hydraulic dredging technique is the most widely used. But during this operation there are load loss exists so it is necessary to find solutions to reduce it. The purpose of this work is to use the Aloe Vera gel as a load loss reducer during hydraulic dredging of dams. To carry out this study, a rheumatic characterization of dams sediments and dams sediments - Aloe Vera gel mixtures was carried out using a torque controlled rheometer (Discovery Hybrid Rheometer DHR2 from TA instrument) and a hydraulic study carried out on a closed-circuit installation comprising three pipes of different diameters and lengths, supplied by a centrifugal pump driven by a variable speed Diesel engine. The experimental work was carried in pipe of diameter D1=36.16 mm and length L1 = 12.24 m with the quantity of Aloe Vera 2 to 10 wt% and different speed of rotation of pump. The flow curves as a function of dose of Aloe Vera added to dam sediments were analysed by the Casson model. The calibration of installation has been fitted by the Blasius equation. The addition of Aloe Vera gel with a quantity range between 2 and 10 wt% to dams sediments of 40 wt% and 45 wt% induces an decrease in the yield stress and the viscosity infinite of dams sediments. The study also demonstrated that adding of 6 wt% of sodium tripolyphosphate to 40 wt% and 45 wt% dam sediments decreased the friction factor by 75% and 85% respectively
