SUMMARY:

Metal-Organic Frameworks (MOFs) are crystalline solids obtained through coordinated bonds between metal ions and organic ligands. Zeolitic-Imidazolate Frameworks (ZIFs) constitute a class of MOFs and are formed from a transition metal and imidazole-based ligands. Recently, this class of materials has gained prominence in various scientific and technological applications in the oil, natural gas, and renewable energy sectors. This demonstrates the versatility of MOFs and encourages the investigation of their applications in the energy sector. In petroleum engineering, drilling fluids are essential for the safety and efficiency of drilling any type of oil well. They are responsible for carrying and suspending drill cuttings, cooling the drill bit and drilling string, cleaning the interface between the bit and the drilled section, and stabilizing formation pressure, which increases with depth. Water-based fluids are generally easy to formulate, inexpensive to maintain, and can be easily modified to overcome most drilling problems. However, these fluids are not efficient in high pressure and high temperature (HPHT) fields due to their relatively poor shale inhibition, lubricity, and thermal stability. Therefore, it is necessary to develop new materials that can be applied in water-based drilling fluids and improve their performance under HPHT conditions, maintaining their rheological properties and filtrate parameters stable. Several MOFs are already well described in the literature and have desirable physical and chemical characteristics for this type of application in drilling fluids, such as high surface area, good adsorption capacity, and thermal and chemical stability. Thus, this work aims to obtain and characterize a ZIF structure and evaluate its potential application in water-based drilling fluid formulations for oil wells, studying its influence and performance under HPHT conditions.
