A computer model of water-in-oil emulsion coagulation
In this thesis, a stochastic computer model of water-in-oil emulsion coagulation, a two stage process of aggregation and coalescence, is presented. The theoretical basis of the model, including equations for the van der Waals, electrostatic and steric energy barriers between dissimilar droplets, is …

Investigation of water-in-oil emulsion on CSI solvent dissolution and ex-solution performance for heavy oil
… phase behavior studies of solvent and heavy oil systems were studied with cleaned tank oil samples only without considering the natural emulsion state of heavy oils, which does not fully reflect the proper fluid flow mechanisms at actual reservoir conditions. Therefore, in this study, the …

Equilibrium Conditions of Hydrate-Forming Pickering Emulsions
A key factor in hydrate risk management for an oil-governing system is the stability of the emulsified water with gas hydrate formation. The kinetics of formation of cyclopentane hydrates is investigated in a water-in-oil emulsion using differential scanning calorimetry with the effect of …

A Comprehensive Study and Mechanism Investigation for Alkaline-Heavy Oil Recovery Process
Alkaline flooding is an important branch of chemical enhanced oil recovery (EOR). The complexity of alkaline flooding study is mainly embodied by its chemical reaction required by alkalis to react with oil acids. Consequently, in-situ surfactants are generated for various emulsification phenomenon. …
