Current growth for Canadian oil and gas exploration and production is taking place in extreme situations, namely in ultra-deep water, in Arctic environments, and in remote locations where cold (sub-zero) temperatures and long pipelines are common. At low temperatures, wax-like compounds present in crude oil may solidify and deposit on the inner wall of pipelines leading to a reduction in throughput and potentially outright blockage. Pipeline development for these harsh environments requires a high degree of certainty on the reliability of the pipeline system and preventative measures designed to avoid plugging. The present research focusses on novel means of preventing this problem, by using a fundamental scientific approach to understand how compounds in crude oil solidify within pipelines. With a greater focus on Arctic and Atlantic exploration, the results of this research will aid the Canadian petrochemical industry implement strategies minimising downtime associated with pipeline blockage.

目前加拿大油气勘探和生产的增长是在极端情况下进行的，即在超深水、北极环境、以及寒冷（零度以下）温度和长管道常见的偏远地区。在低温下，原油中存在的蜡状化合物可能会凝固并沉积在管道内壁上，导致产量降低，甚至可能完全堵塞。针对这些恶劣环境的管道开发，需要高度确定管道系统的可靠性和预防措施，以避免堵塞。目前的研究重点是通过使用基础科学方法来了解原油中的化合物如何在管道内固化，从而找到防止这一问题的新方法。随着对北极和大西洋勘探的更多关注，这项研究的结果将有助于加拿大石化行业实施战略，最大限度地减少与管道堵塞相关的停机时间。
