TITLE
Evaluation of Surfactants for Oil Recovery Potential in Shale Reservoirs

BRIEF
Most shale reservoirs have a low permeability, low porosity, oil-wet character with natural fractures that contributes to low oil recovery factors. In this study, various surfactants (non-ionic, cationic, anionic, and amphoteric) were studied for spontaneous imbibition into oil-wet shale cores in order to investigate the effect of salinity, surfactant concentration, electrolyte concentration and temperature on the wettability alteration and provide mechanisms.

TITLE
Interfacial Films and Stability of SAGD Emulsions: Effect of Reverse Emulsion Breakers

BRIEF
Reverse emulsion breakers (REBs) had three effects on film properties, which correlated well with lowering emulsion stability: (1) decreasing interfacial tension (IFT); (2) causing the film to be reversible, which destroyed the asphaltene cross-linked network and resulted in faster phase separation and (3) inducing drop detachment. Effective REBs formed complexes with natural anionic surfactants present in the oil phase that significantly lowered the IFT, replaced asphaltenes at the interface with a reversible film or weakened the irreversible film.

TITLE
The Potential of Chemical Additives to Increase Heavy Resid Processing Efficiency

BRIEF
The authors developed a versatile reactor unit for investigating relative fouling tendency of resid feedstock. In their investigation, thermal resistance measurements were sensitive to various feedstock compositions, feedstock blending and additive application. A multi-dimensional characterization revealed that certain feedstock compositions have greater preference for surface fouling over bulk coke formation, and this fouling tendency dictates design of chemical additive treatment programs.
