  4. Abstract:
  5. During the drilling operation in high-permeability, natural and artificial fractured formations, the lost circulation of drilling mud is a common problem. Various methods have been applied to control lost circulation and among these methods, using Lost Circulation Materials (LCM) is the most common method that blocks the fluid loss channels in the formation by creating structures. In this project, the aim is to develop and use natural fiber-reinforced composites as LCM can be an innovative and technical solution. Natural fiber-reinforced composites have excellent properties such as high specific strength, non-abrasive, eco-friendly, and biodegradability. It seems to be possible that manufacturing composite can provide more desirable properties by changing its formulation. In this work, the Bagasse Fiber Reinforced Polymer (BFRP) composites were prepared with a twin-screw extruder and tested in Bridging Material Tester (BMT) with a slotted disk based on API standard. Finally, the obtained results were compared with those obtained using some conventional LCM's. In addition, the effect of the fiber content on the mechanical properties has also been evaluated. At 30% Bagasse fiber loadings, BFRP composite shows better mechanical properties compared to those of 40% fiber content BFRP composite. Also, fractured surface and Fiber-PP interaction have been studied by Scanning Electron Microscopy (SEM). The results show that the BFRP composite creates a suitable and persistent bridge inside the fractures and was able to seal slotted disks up to 0.12-in. Moreover, a reasonable combination of BFRP composite and Bagasse fiber increase plug breaking pressure contributing to reduce fluid loss can cause less fluid invasion upon the establishment of an effective seal. Optimal selection of size distribution leads to building a network for opening of fractured formations by Bagasse fiber. Also, BFRP granular particles can fill the empty space as well as reducing the amount of leakage. This study proposes new insights into the design of engineered loss control material with more effective loss formation control ability. © 2022 Elsevier B.V
