Method for improving fluid recoveries from earthen formations

摘要: This is a method for the in-situ placement of barrier to fluid flow in openings subterranean deposits. A number wells are drilled communication with deposit, and barrier-forming injected into deposit through on wells. driving introduced excluding from communicating between Other not being used introduction flows closed during this step, except monitoring suitable detect fluid. The other opened after detection circulate barrier- forming (9 claims)
