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…

Abstract: Abstract This work aims at studying a new idea for cold transportation of high-viscosity oil by foam injection. Special attention is paid to the drag reduction achieved by introducing a non-Newtonian aqueous foam to Newtonian…

Abstract: Abstract Steam-based recovery methods are usually employed to recover heavy and viscous oils, but they are not efficient in deep and thin oil reservoirs. Chemical flooding is studied here to improve recovery of a viscous…

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…

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…

Abstract: The steam-assisted gravity-drainage (SAGD) method has emerged as among the leading methods of enhanced oil recovery and is predicated on the injection of steam within the wellbore followed by extraction of emulsions of viscous oil…
