Patent
·
OSTI ID:6080309
In the described method, steam is injected into an aquifer underlying a heavy oil reservoir to heat the reservoir and increase production, primarily by decreasing viscosity. A single steam injection-oil production well may be used along with a number of surrounding water- producing wells. A well-to-well displacement with one steam injection well, a set of surrounding water-producing wells, and another set of surrounding oil-producing wells, may also be used, the 2 sets being respectively, at the corners of the 5-spot and at the midpoint of the border lines.
