| dc.description.abstract | This master's thesis delves into the investigation of the influential factors that affect the lost circulation material’s bridging performance at a fracture gate. The study begins by examining the quartz particles bridging performance at different fracture widths, followed by the investigation of the drilling fluids' viscosity and lubricity impacts on the particles bridging stability behavior. Additionally, the study assesses the potential enhancement of quartz performance through fiber reinforcement.
The research findings reveal that the incorporation of fibers indeed improves the bridging performance of quartz particles. Moreover, an intriguing trend emerges when examining the effect of viscosity on bridging performance. The analysis considers the Bingham Plastic, Power Law, and Herschel-Buklkey's rheological parameter. Results exhibited that an increase in these parameters correlates with a rise in the average bridging pressure across different selected slot sizes.
Furthermore, the study investigates the impact of lubricity by comparing the coefficient of friction (COF) between two selected fluids. The test results showed that the fluid with a higher COF (less lubricity) demonstrates better particle bridging stability when compared with the fluid exhibiting a lower COF (high lubricity).
In summary, this research emphasizes the crucial role of fiber reinforcement in enhancing the bridging performance of quartz particles. Additionally, it highlights the notable effects of viscosity and lubricity on bridging behavior, providing valuable insights for optimizing and improving the performance of quartz-based systems. | |
