Knowing the impact of technical solutions on the drilling process is a very important element in the process of the exploration of new fossil fuel deposits. Drilling equipment used during drilling operations is highly liable to all conditions which prevail in the well bore. The study of the impact of drilling fluid flow with various rheological properties on the strength and work of drill stem components will allow to search for the best solutions. The article describes the design and construction of two boreholes, fill up with 9 5/8" (244.5 mm) and 24" (609.6 mm) casings. The designed boreholes will be a joint part of the drilling laboratory in the S-1 building at AGH-UST in Krakow. Research The research described above can be done in openholes and implemented at the beginning of the design process for drilling works in new deposits. In addition, it will provide an opportunity for all engineers to get to know the behavior of components operating in an open hole.
