Abstract
The present invention relates to methods for controlling the migration of unconsolidated particulates in a portion of a subterranean formation, and more particularly, to the using a pressure pulse to enhance the effectiveness of placement of a consolidation fluid in a portion of a subterranean formation. Some methods of the present invention provide methods of treating a subterranean formation comprising injecting a consolidation fluid into the subterranean formation while periodically applying a pressure pulse having a given amplitude and frequency to the consolidation fluid.
Claims48
A method of treating a subterranean formation penetrated by a well bore comprising:
- injecting a consolidation fluid thereby effecting a more uniform penetration of the consolidation fluid into the subterranean formation into the subterranean formation while periodically applying a pressure pulse having a given amplitude and frequency to the consolidation fluid.
A method of controlling the migration of unconsolidated particulates in a portion of a subterranean formation penetrated by a well bore comprising:
- injecting a consolidation fluid into the well bore and into the subterranean formation while periodically applying a pressure pulse having a given amplitude and frequency to the consolidation fluid thereby effecting a more uniform penetration of the consolidation fluid into the subterranean formation;
- and,
- allowing the consolidation fluid to control the migration of unconsolidated particulates.
A method of using a pressure pulse to enhance the effectiveness of placement of a consolidation fluid in a portion of a subterranean formation penetrated by a well bore, comprising injecting a consolidation fluid into the well bore and into the subterranean formation while periodically applying a pressure pulse having a given amplitude and frequency to the consolidation fluid so as to more uniformly place the consolidation fluid in the portion of the subterranean formation.
