Abstract Applied to Enhanced Oil Recovery, microemulsions are valuable systems for
extracting the crude oil trapped by capillary forces in the porous reservoir rocks. The …

Surfactant flooding is a chemical enhanced oil recovery (EOR) process which consists in
injecting optimized formulations of surfactants in the reservoir in order to remobilize the …

Surfactant formulations that give rise to ultra-low interfacial tensions are used to enhance the
recovery of crude oil by eliminating the trapping effects of capillary forces. The formulations …

Emulsions are colloidal systems which consist of discrete dispersions of droplets of one
liquid phase within another immiscible liquid phase. They occur naturally (eg milk and …

Hypotheses The performance of bicontinuous microemulsions is usually assessed on the
characteristics of the middle phase at equilibrium. However, applied to Enhanced Oil …

In enhanced oil recovery (EOR) surfactants are used to reduce the oil/brine interfacial
tension (IFT) by several orders of magnitude to mobilize and produce residual, capillary …

In situ formation of microemulsions is studied by co-injection of its individual phases:
surfactant solution and decane oil. The experiments were conducted in micro-channels …

Water-in-oil emulsions constitute a widespread issue for the oilfield industry. Indeed, the
phases of water-in-oil emulsions must be separated as soon as possible in the production …

In our previous report we suggested a new analytical tool, high accuracy NMR chemical shift
corrected for bulk magnetization as a supplementary tool to study structural transitions and …

In microemulsions, changes in droplet size and shape and possible transformations occur
under various conditions. They are difficult to characterize by most analytical tools because …
