Recovery of oil |
摘要 |
A method of recovering oil from a subterranean formation which includes an association production well involves contacting oil in the formation with a treatment fluid formulation which includes polyvinylalcohol and collecting oil which is being contacted with said treatment fluid formulation by said production well. Use of the polyvinylalcohol, optionally in combination with other materials, facilitates recovery of oil from subterranean formation, particularly those involving medium or high viscosity oils. |
