Abstract
The paper discusses particulars of technological solutions for high-viscosity reservoirs with the underlying contact water zone developed by thermal recovery methods. Analytical methods were used to calculate temperature distribution in a reservoir once hot water and steam have been injected into the oil zone and the underlying contact water zone. The results of the calculations yielded analytical dependencies to determine the radius of the thermal front that is formed in the oil zone. These dependencies showed that the radius of the thermal front in the oil zone resulting from the injection of hot water into the underlying contact water zone below the WOC is 1.24 times the radius of the thermal front resulting from the hot water injection directly into the oil zone. However, when steam is used as a heat carrier, it makes little difference, as far as the steam chambers’ sizes are concerned, whether the steam is injected directly into the oil zone, or into the underlying contact water zone.
