Global demand for crude oil has grown significantly over the past two decades. However, conventional light crude oil production is declining, and more and more deposits of heavy and waxy oil, including high waxy ones, are being developed, creating new technological challenges at every level of the process, from production to transportation and refining. Among the various problems, the main one is wax deposition. Since the costs of maintenance, repair, and achieving the required low-temperature properties of commercial oil products are very high, solving this problem becomes critical. The paper discusses the existing problems of production, transportation, and refining of waxy crude oil and analyzes the methods of their solution.
