AI Technical Summary
Existing wellbore isolation tools used in multi-stage hydraulic fracturing operations face issues such as failure during high pressure, deformation, and incomplete dissolution, leading to operational challenges and costly debris removal processes, which affect the integrity and efficiency of fracturing operations.
A wellbore isolation apparatus with a valve assembly and actuator system that can be controllably activated using a modified wireline tool, allowing for secure isolation of wellbore segments, withstanding pressure testing, and dissolving at a predetermined time to restore the casing diameter, utilizing a flapper valve and telescopically movable tubulars actuated by fluid release mechanisms.
The apparatus enables reliable wellbore isolation and fluid communication control during fracturing, ensuring operational integrity and reducing the need for costly debris removal, while allowing for subsequent restoration of the casing for further operations.
