... Abstract This experimental study was designed to provide a detailed understanding of the blocking mechanism of heavy oil-in-water emulsions injected into a porous medium. The process in mind is one where a created emulsion will break near the well bore or at some pre-determined distance from...

...-surfactant flooding of heavy oil systems as well, and it has been observed that chemical injection can lead to improved oil recovery. The heavy oil recovery mechanism proposed in this work is the creation of oil-in-water emulsions, which may form under conditions of low interfacial tension and shear due...

... Abstract Many abandoned gas wells in western Canada leak gas to the surface. This paper presents the results of an experimental study to determine the possibility of using an asphalt-in-water emulsion as sealant for these abandoned leaky wells as a more efficient and cost-effective alternative...

The technology of aerated O/W emulsion for workover operations, is an alternative to solve these problems. The successful application of this technology begins with an adequate selection of the wells and a proper design...

Free-oil is defined as an oil droplet of 150 microns, which will float immediately to the surface due to its large size and high rise velocity. Emulsion is oil which is dispersed in the water in a stable fashion due to its small diameter and thus...

Data from successful field tests near Cold Lake, Alberta, Canada, shows that the instrument is capable of making water cut measurements over a wide range of fluid types and temperatures. The instrument is capable of functioning accurately where a wide range of emulsions and/or foams...

... Abstract Stable oil-in-water emulsions are very difficult to break and constitute one of the most difficult problems encountered during oil production. The emulsion viscosity is much higher than that of the segregated phases and, therefore, accounts of high pressure drop in the wellbore...
