... reported, and they show significant oil recovery at high water cut. However, the range of reported recovery is large – waterflood recoveries of ~ 1-2% to 20% OOIP have been reported for similar reservoirs. Higher viscosities result in lower recovery Mechanistic study using fine-scale simulations show...

... and/or butane) and a commercially available non-condensable gas (methane, natural gas) is injected into the reservoir to reduce the oil viscosity. Therefore, the cost of these injected gases per barrel of produced oil is critical for the economic viability of the process. With predicted increase in the gas...
