Abstract
Abstract This paper described an investigation into the properties of water-in-heavy oil emulsion and its role in enhanced oil recovery (EOR). Effect of pH and salinity on emulsion stability, droplet size and distribution as well as rheological behavior were researched. Core flooding experiments were conducted to study the role of emulsion on EOR. Results indicated that stability of emulsions decreased as salinity increased. The presence of salt leads to a rise in droplet size and a drop in uniformity of distribution. Besides, emulsion formed at pH of 7 was characterized by the least stability, largest droplet size and unevenest droplet size distribution. An increase or decrease in pH both improved emulsion stability and reduced droplet size. Equally, rheological property of emulsion was greatly affected by salinity and pH. In relatively low shear rate region (
