Course Credit: 0.1 CEU, 1 PDH

Asphaltene deposition is a common cause of significant flow assurance problems in wellbores and production equipment as well as near-wellbore regions in oil reservoirs. Asphaltenes are surface-active and stabilize water-in-oil emulsions by flocculating and coagulating at interfaces. Commercial dispersants have been developed to mitigate asphaltene deposition, but their role on the interfacial properties of asphaltene films is unclear. The presenter’s lab has generated micromodels, which are combined with high-speed imaging to visualize asphaltene deposition and transport in microfluidic devices with permeability contrasts, fractures, and multiple phases. The surfaces can be altered to mimic the chemistry and wettability found in reservoir systems. The presenter will discuss how these devices can be utilized to advance our understanding of oil flow processes and design better strategies to address flow assurance problems.
