... The total reduction in fluid transfer ability due to suspended solids and oil emulsions consists of two parts. (a) Internal in-situ damage in the porous medium due to deep filtration of solid particles and/or oil emulsions. The pressure increase due to internal damage will be referred to as build...

... polyimine. Commercial product 2 provided some performance but the phase separation observed for the emulsions tested varied between 60-80% of Formulation 1. Commercial product 3 gave the poorest performance, with almost no separation for the 3 crude oils used, under the specified testing conditions. Case...

... was used as an emulsifier. The emulsified polymer gel system was characterized by dilution test, microscopic analysis and gel strength code. The developed emulsified polymer gel was found to be water-in-oil emulsion system, which formed rigid gel (gel strength grade-I) under reservoir temperature...

... Abstract A novel approach to exploit thermal energy released from the exothermic reactions of aqueous solution of thermochemical reactants (ammonium chloride and sodium nitrite), in controlling formation damage induced by water-in-oil emulsion have been investigated. Essentially, the technology...

... In general, emulsions consist of droplets formed as a result of combining two immiscible liquids, e.g. oil and water ( Bibette and Leal-Calderon 1996 ). They are ubiquitous in our daily lives ranging from food to cosmetics to industrial and consumer products such as paints and pharmaceuticals...

Tests included compatibility with formation brine, emulsion tendency, recovery factors from spontaneous imbibition with crude oil and formation brine, and compatibility with proposed fracturing fluids. These results show that more than one...

... Abstract Formation damage caused by water-in-crude oil emulsions can have a big impact on oil production. Chemical treatment is often applied by injecting surfactants known as demulsifiers to break the water-in-crude oil emulsions. Common demulsifiers used in the oilfield industry often contain...
