Leak Point Identification

Critical for Effective Intervention and Repair Identifying and assessing leak points is crucial before planning any intervention or repair work. Understanding the leak depth and path allows for more efficient and reliable operations, ultimately saving time and increasing the likelihood of a successful remediation. ScanWell utilizes a variety of instruments and methods to locate leak points, tailored to the specific source and path of the leak. By combining these measurements, we can accurately determine leak depth and deliver reliable results to our clients, that are fully documented and traceable.

ScanWell’s interventionless downhole leak diagnostics combine surface pressure analysis, compositional evaluation, and advanced tracing techniques to accurately identify leak points. This tailored approach ensures efficient repairs, reduces downtime, and increases the success of remediation efforts. With comprehensive, traceable results, ScanWell empowers operators to manage the risk associated with potential downhole leaks.

Identifying and assessing downhole leaks is vital to evaluate the risk associated with the condition, evaluate mitigation measures, and ensure effective interventions and repairs. These leaks can occur in annular volumes, communicate with shallow formations, or connect to the main reservoir, posing significant operational risks. Key considerations include:

• Leak Depth: Understanding the depth of the leak is essential for selecting the appropriate tools and techniques for repair, especially in deep annular volumes.
• Leak Path: Pinpointing the leak’s trajectory helps evaluate its impact and design effective remediation strategies.
• Operational Efficiency: Accurate diagnostics reduce downtime, prevent unnecessary interventions, and improve repair success rates.

With precise identification of leak points, ScanWell enables operators to approach repairs confidently, minimizing disruptions and ensuring effective outcomes.

ScanWell’s Interventionless Approach to Downhole Leak Diagnostics

Traditionally, assessing deep downhole leaks required intrusive methods, such as deploying downhole noise tools with help of wireline and slickline. ScanWell has developed advanced, interventionless techniques that provide accurate leak diagnostics without disrupting operations. These include:

1. Surface Pressure Diagnostics:
   • Monitors pressure changes while bleeding and pressure build-up sequences.
   • Helps identify potential communication in annular volumes or well casings.
2. Compositional Analysis:
   • Analyses fluid samples to evaluate the source of the of the leak.
   • Typically differentiates between leaks from shallow formations or deeper zones.
3. Direct Leak Tracing:
   • Uses proprietary direct leak tracing method to confirm communication between adjacent cavities and calculate the depth of the leak.
   • Provides clear insights into the leak path and potential points of communication with formations.
4. Top and Displacing Techniques:
   • Unique in-house developed method Involving controlled displacement of wellbore fluids to measure pressure responses and locate leaks.
   • Effective for determining the source and depth of downhole leaks.

Accurate Depth and Path Determination

ScanWell’s combined methods provide:

• Leak Depth: Pinpoint measurements of the leak’s location within the wellbore or annular volumes, ensuring targeted repairs.
• Leak Path: Traces the fluid flow to assess the path of the leak between the annular volumes.

This data is crucial for designing efficient repair plans and understanding the potential risks associated with the leak.

Fully Documented, Traceable Results

• Accurate and Reliable Data: Ensures precision in identifying leak depth and path.
• Traceable Diagnostics: All measurements and methods are fully documented, ensuring compliance and transparency.
• Comprehensive Reports: Includes all relevant information—leak location, source, and path—providing quality data to make informed decisions.

These detailed results enhance planning and optimize ongoing maintenance.
