Most energy forecasts point to continued growth in the worldwide petroleum demand. However, new heavy- oil reservoirs are deep and located offshore, necessitating costly and complex infrastructure and operations. One serious challenge with deepwater petroleum production is the solids or wax deposition, which can cause plugging of pipelines and process equipment, requiring hundreds of millions of dollars for its control and remediation. Wax deposition involves liquid-to-solid phase transformation of paraffins, which is a complex process influenced by cooling or crystallization rates, thermal and shear histories, and the composition.

大多数能源预测指出，全球石油需求将继续增长。 然而，新的重油储藏很深，位于近海，需要昂贵和复杂的基础设施和作业。 深水石油生产的一个严重挑战是固体或蜡沉积，这可能导致管道和工艺设备堵塞，需要数亿美元的控制和补救。 蜡沉积涉及石蜡的液-固相转化，这是一个受冷却或结晶速率、热和剪切历史以及组成影响的复杂过程。
