  • Frac plug setting tool with triggered ball release capability
    Patent number: 11326409
    Abstract: A downhole tool and process for introducing the downhole tool into a wellbore are provided wherein the downhole tool includes an occlusion-releasing tool. The occlusion-releasing tool contains an occlusion until such time as it is needed in a frac plug to prevent flow in one direction in the wellbore. The occlusion is released from the occlusion-releasing tool by fluid flow through the occlusion-releasing tool. The fluid flow acts directly on the occlusion to provide sufficient pressure to release the occlusion from a mechanical retainer.
    Type: Grant

    Date of Patent: May 10, 2022
    Assignee: Halliburton Energy Services, Inc.
