Proceedings Papers

Paper presented at the SPE Heavy Oil Conference-Canada, June 10–12, 2014
Paper Number: SPE-170028-MS
... prepared systems analyzed using a variety of techniques, including dielectric spectroscopy, UV-Vis spectrophotometry, sedimentation analysis and adsorption isotherms. Dielectric measurements were undertaken on a range of artificially prepared samples analyzed at moderately low frequencies (10 -2 to 10 7...

...), thermal solvent, and steam-solvent) can be economically viable. In particular, CSI is a promising post-CHOPS follow-up process. Sources of solvent loss / retention include: Solvent trapped in the reservoir due to surface and interfacial forces including adsorption and capillary pressure Solvent...

Paper Number: SPE-165506-MS
... of asphaltene precipitation but the adsorption of asphaltene on rock surfaces and its impact on multiphase flow are not yet well understood. In this work, the effects of asphaltene adsorption on wettability, relative permeability, and displacement efficiency in porous media were evaluated using flow...

... reservoirs is of great concern in petroleum and environmental engineering. The objective of this work is to study mass transfer between the matrix and the fracture network in such complex formations. In this study, the impact of adsorption on mass transfer in a fractured medium with variable fracture spacing...
