DOI: 10.1007/s10553-019-01047-z
Abstract: The methods of extracting viscous oil from oil leg reservoir (oil rims) of the Cenomanian horizon are experimentally investigated (PK layers). It was found that steam contributes to the swelling and dispersion of clay components… read more here.

DOI: 10.1016/j.ijmultiphaseflow.2021.103892
Abstract: Abstract Eccentric core-annular flow is encountered in water-lubricated transport of highly viscous oil in horizontal pipes. The core eccentricity results from the tendency of the phases to stratify due to a buoyant force that results… read more here.

DOI: 10.1021/acs.energyfuels.7b00790
Abstract: Waterflood in a viscous oil reservoir is not very efficient because the water fingers through the oil due to adverse viscosity. Typically, thermal methods are used to recover viscous (and heavy) oil. However, thermal methods… read more here.
