Abstract
Several heavy oil fi elds in Oman are undergoing a rejuvenation using a variety of Improved and Enhanced Oil Recovery methods. The<br>sandstone reservoirs, generally at a depth around 1000 meters, contain heavy oils with API gravities of 18-22, viscosities between 90-<br>400 cp and exhibit variable reservoir properties of around 20% porosity and 500-2000 mD permeability. Mobility ratios are adverse and<br>all fi elds demonstrate early water breakthrough and high BSW under primary development.
