  • Dissolvable bridge plug
    Patent number: 10316616
    Abstract: A dissolvable bridge plug configured with components for maintaining anchoring and structural integrity for high pressure applications. These components may substantially dissolve to allow for ease of plug removal following such applications. The plug may effectively provide isolation in a cased well for applications generating over about 8,000-10,000 psi. At the same time, by employment of a dissolve period for the noted components, such a plug may be drilled-out in less than about 30 minutes, even where disposed in a lateral leg of the well.
    Type: Grant

  • DISSOLVABLE BRIDGE PLUG
    Publication number: 20110048743
    Abstract: A dissolvable bridge plug configured with components for maintaining anchoring and structural integrity for high pressure applications. Embodiments of the plug are configured such that these components may substantially dissolve to allow for ease of plug removal following such applications. In one embodiment the plug may effectively provide isolation in a cased well for applications generating over about 8,000-10,000 psi. At the same time, by employment of a dissolve period for the noted components, such a plug may be drilled-out in less than about 30 minutes, even where disposed in a lateral leg of the well.
