The introduction of the diesel base fluid (OBM) in Cuban oil drilling was the solution to enormous expenses due to loss of tools, damage to the reservoirs and other problems that occurred when only aqueous fluid was used during oil drilling in complex geological zones. However, both the initial costs and the risk of affecting the ecosystem are very high. It is therefore crucial to properly treat the cuttings that emerge to the surface impregnated with diesel and to guarantee a safe final destination for them. The introduction of the circular economy concept made it possible to demonstrate that it is possible to valorize drilling waste for the manufacture of asphalt concretes, as sub-bases in asphalt mixtures for roads. The results show that the production chain guarantees the safe final disposal of a polluting waste and economizes the production of asphalt concrete. The solution to the destination of the cuttings guarantees the continuity of Cuban oil drilling.
