Secondary recovery method
Patent

OSTI ID:6620939
A method of secondary recovery of oil from subterranean reservoirs is described wherein a fluid is used to drive the oil in the reservoir to production wells. This driving fluid is a mixture of water and colloidal silica. The driving fluid has a mobility ratio relative to the oil in the reservoir such that the driving fluid will maintain a flat face against the oil being driven to production wells and thus a high sweep efficiency of the reservoir will result.
