As part of the scientific activities of the Department of Chemical Engineering and Petroleum Industries, a scientific seminar entitled “Evaluating Rheological Properties and Thermal Stability of Reservoir Drilling Fluid (RDF) Using Nanoparticle Size Materials” was held and delivered by Lecturer Assistant Zaid Emad Mohsen. The seminar addressed the latest research on developing reservoir drilling fluids using nanomaterials. The seminar highlighted the importance of evaluating the rheological properties of drilling fluids and the impact of adding fine-sized nanoparticles in enhancing viscosity, flow behavior, and cuttings transport efficiency, as well as improving the thermal stability of the fluid under high-temperature and high-pressure reservoir conditions. This seminar aligns with Sustainable Development Goal 9 (Industry, Innovation, and Infrastructure) adopted by the United Nations through supporting scientific research and developing advanced technologies that enhance industrial process efficiency. It is also connected to Sustainable Development Goal 12 (Responsible Consumption and Production) by improving material utilization and reducing waste during drilling operations.
