Patch & Seal Verifications
A patch in the wellbore is ofte used to seal off a section where there may be several leaks. A Plug in the wellbore is typically set to isolate the wellbore above the plug from the reservoir. Both components serve as barriers preventing hydrocarbons to unintentionally enter the wellbore, and consequently the integrity of these components becomes important to evaluate and assess.
Patch, Plug and Seal Checks
The integrity of patches, plugs, and seals is vital for maintaining safe and compliant well operations. ScanWell’s cutting-edge testing methods, including direct leak metering, acoustic diagnostics, and gas composition analysis, ensure accurate evaluations and reliable results. By maintaining these critical components, operators can confidently manage their wells, enhance safety, and prevent costly interventions.
Evaluating Patches, Plugs, and Seals: Ensuring Well Integrity
Patches and plugs are essential barriers in the wellbore that prevent the unintended flow of hydrocarbons, safeguarding well integrity and operational safety.
- Patches: Seal off sections of the wellbore with potential multiple leaks.
- Plugs: Isolate the wellbore above the plug from the reservoir, ensuring controlled operations.
- Critical Role: Both components act as barriers against hydrocarbon entry, making their integrity crucial for safe operations and compliance with regulations.
Maintaining Integrity for Safe Operations
Regular assessment of patches, plugs, and seals ensures:
- Safe Operations: Prevents uncontrolled hydrocarbon influx, minimizing risks to personnel and the environment.
- Regulatory Compliance: Meets industry standards for well integrity and leak prevention.
- Long-Term Reliability: Proactively identifies weaknesses, reducing unplanned interventions and downtime.
Integrity Testing with ScanWell Solutions
ScanWell employs advanced techniques to evaluate the condition of patches, plugs, and seals, ensuring they maintain their barrier function effectively.
- Inflow Leak Testing:
- Direct Leak Metering: Precisely measures any potential leak rates to identify weaknesses in barriers.
- Acoustic Instruments: Detect liquid influx by analyzing sound signatures within the wellbore, providing non-invasive diagnostics.
- Gas Composition Analysis:
- Examines vented gas for hydrocarbon content to detect early signs of reservoir communication or leaks.
- Helps pinpoint the source of a potential breach, enabling targeted repairs.
