Based in Nisku, Hilong Petropipe Company Ltd. provides a variety of pipe coating options designed to prevent the internal surfaces of drill pipes and oil tubing against downhole erosion and abrasion, as well as reduce the friction and turbulence, thus enhancing flow efficiency in oil wells. Despite the overall good feedback from the customers on the coating service, some customers have reported some difficulty for the coated oil tubing to meet the production requirements in Cold Heavy Oil Production with Sand (CHOPS) wells. Because Hilong's tubing coatings are designed to be used in conventional light-oil wells, it is questionable if they perform equally well in Canadian CHOPS wells. The overall objective of this study is to primarily evaluate the performance of Hilong' internal coatings in CHOPS wells through examining the flow efficiency of sand-laden heavy oil in these coated tubing. The research results from this project help Hilong to develop new coating products that perform better for CHOPS wells.

海隆石油管道有限公司总部位于尼斯库，提供各种管道涂层选项，旨在防止钻杆和油管的内表面受到井下侵蚀和磨损，并减少摩擦和湍流，从而提高威尔斯油井的流动效率。尽管客户对涂层服务的总体反馈良好，但一些客户报告说，涂层油管难以满足含砂冷采稠油（CHOPS）威尔斯井的生产要求。由于海隆的油管涂料设计用于传统的轻油威尔斯井，因此它们在加拿大CHOPS威尔斯井中是否表现同样出色值得怀疑。本研究的总体目标是通过检测含砂稠油在这些涂层油管中的流动效率来初步评价海隆公司的内涂层在CHOPS威尔斯井中的性能。该项目的研究成果有助于海隆开发新的涂层产品，更好地为CHOPS威尔斯井。
