Annular Integrity Checks

Essential for Safety on Oil and Gas Facilities Annular integrity checks are crucial for ensuring the safety of oil and gas production facilities. These tests verify the integrity of well barriers and focus on assessing risk factors that could lead to severe incidents.

ScanWell conducts over 1,500 integrity checks annually, leveraging more than 15 years of experience in this specialized service. Our approach allows for a comprehensive assessment of annular integrity without intervention in the wellbore, ensuring no loss of production.

Key Risk Factors Evaluated During Annular Integrity Checks:

Pressure: A fully functional barrier should exhibit no pressure in the annular volumes. Any positive or negative pressure indicates potential degradation of the barrier and necessitates further assessment. Mitigating action should be taken to reduce the overall risk.

Gas Volume: The presence of compressed gas in the annular space introduces a risk factor that requires careful evaluation and mitigation where possible.

Leak Rate: The preferred method for accurate and dynamic leak rate measurements is by Direct Leak Metering. ScanWell utilizes custom equipment and a patented method to accurately measure the leak rate of gas, liquid, or mixed fluids.

Toxic and Corrosive Components: The presence of these components introduces a risk factor that should be included in any risk assessment. Corrosive components may affect current and future Maximum Allowable Surface Pressure (MASP) and Minimum Operating Pressure (MOP). Toxic components introduce a safety hazard. Both are likely to have an impact on the future testing frequency.

Leak Depth and Path: Understanding the depth and path of any leaks is vital for evaluating potential risks. This assessment is required before implementing any mitigation strategies and for understanding the possible risks of escalation.
