This paper aims to design a less toxic drilling fluid by testing different organic waste materials. The drilling mud is a complex fluid consisting of several additives used in the drilling process. Environmental protection is a crucial issue, and several drilling fluids and additives can have negative impacts on people, marine organisms, and plants. The selection of organic additives depends on safety concerns and the effect on the environment. The paper focuses on testing coffee residue, date seeds, and rice husks as organic additives in drilling fluids. The selection of these organic wastes was based on several factors, including cost, availability, and positive environmental impact. The properties of the mud samples, including rheology, mud filtration, and pH, were measured to determine the effect of the organic waste additives. The results showed that coffee residue can improve the lubrication properties of the fluid, and date seeds can increase the density of the fluid. Rice husks did not significantly impact the properties of the drilling fluid. The use of these organic additives can reduce the environmental impact caused by conventional additives, promoting a more sustainable and circular economy.

Wellbore instability, particularly in shale formations, presents a great challenge to modern drilling operations. Although conventional chemical inhibitors are frequently employed in water-based drilling fluids, they may not always function in highly reactive or naturally fractured shale formations. In recent years, mechanical inhibitors have attracted attention as a complementary solution to chemical methods. These inhibitors, which include carbon-based, silicon-based, metal-based, and mineral-based particle materials, provide structural support to the wellbore by physically plugging fractures and sealing microfractures. This paper presents a comprehensive review of the mineral types associated with shale wellbore instability as well as a critical analysis of the mechanisms, categories, and effectiveness of mechanical inhibitors in enhancing wellbore stability. The development challenges and prospects of mechanical inhibitors in water-based drilling fluids are also discussed. This review emphasizes the potential of mechanical inhibitors in reducing fluid invasion, preventing wellbore collapse, and improving overall drilling efficiency, which will help facilitate the development and large-scale application of mechanical inhibitors in drilling fluids.
