Laboratory and Theoretical Determination of Asphaltene Precipitation/Deposition/Inhibition in Canadian Oil Reservoirs

沥青质是一种化学芳香族化合物，在一定的热力学条件和流体特性下可能会析出。沥青质沉淀/沉积可通过润湿性改变和堵塞机制影响石油生产和运输作业。这种不受欢迎的行为在加拿大各地的许多油藏中都存在，导致了巨大的资本/运营成本和环境问题。为了更好地设计、实施和控制石油生产作业，进一步了解和更准确地预测储集岩中的沥青质特征和沉淀/沉积过程是至关重要的。

Asphaltenes are chemical aromatic compounds that may precipitate at certain thermodynamic conditions and fluid characteristics. Oil production and transportation operations can be affected by asphaltene precipitation/deposition through wettability alteration and blockage mechanisms. This undesirable behavior is found in many oil reservoirs across Canada, resulting in significant capital / operating costs and environmental issues. Further understanding and more accurate prediction of asphaltene characteristics and precipitation/deposition processes in reservoir rocks are vital for better design, implementation, and control of oil production operations.
