Interface advance control in secondary recovery program by reshaping of the interface between driving and driven fluids
It is understood that the failure of the driving flood in secondary recovery operations to contact or sweep all of the hydrocarbon area is due to the development of a cusp at the interface between the driving and the driven fluids which advances toward the production well. If other portions of the interface could be made to keep up, or if the cusp formation were delayed, a more complete areal sweep would be possible. A secondary recovery procedure is provided which involves initially at least 2 production wells in line with a source of driving fluid (such as an injection well or active aquifer) for exploiting a hydrocarbon-bearing formation by reshaping the interface between a driving fluid and formation fluids, after development of a cusp, into a configuration favorable to greater sweep.
