LDAR services for methane emissions management
Detect, classify, and document fugitive emissions with LDAR surveys from SLB to meet regulations, cut methane, and verify repairs
Fugitive methane emissions add cost, risk, and regulatory exposure. SLB LDAR surveys combine optical gas imaging (OGI), structured workflows, and digital reporting to identify, quantify, and document leaks—so you can prioritize repairs, verify fixes, and demonstrate compliance.
Where LDAR surveys deliver value
- Onshore production facilities: Routine inspection routes to surface intermittent and small leaks; digital logs simplify audit readiness.
- Gas processing and compression: OGI and quantification at high-throughput sites to curb losses and verify maintenance outcomes.
- Refining and petrochemical complexes: Tagged component surveys aligned to LDAR regulations; rapid classification for work orders.
- Storage and loading terminals: Detection on valves, flanges, pumps, and seals to reduce product loss and odor complaints.
- Manufacturing sites: Programmatic monitoring to meet corporate methane-intensity targets.
Cut emissions, prove compliance, and lower total cost of leaks
Faster leak-to-repair cycle
Streamlined detection, notification, and work order workflows reduce time to repair.
Audit-ready documentation
Time-stamped images, component IDs, and classification notes support regulatory reporting.
Targeted maintenance spend
Quantification data helps prioritize high-impact repairs.
Sustainability impact
Reducing fugitive methane supports corporate ESG goals and local air quality commitments.
Operational assurance
Follow-up surveys verify fix effectiveness and prevent recurrence.
Comprehensive LDAR services from detection to verification
-
Optical gas imaging (OGI) surveys: Trained technicians use OGI to detect and visualize emissions, including sources invisible to the naked eye.
-
Leak classification: Categorization by size/severity with component tagging for clear routing to maintenance.
-
Quantification: Measurement of concentration/volume to inform severity and repair priority.
-
Digital documentation: On-image annotations, component metadata, and route logs for compliance and traceability.
-
Regulatory reporting: Findings packaged for local LDAR regulations and corporate reporting requirements.
-
Repair & re-survey: Verification after fixes; optional periodic follow-ups to validate sustained performance.
Our team brings extensive field expertise to help teams execute routine maintenance programs, navigate evolving regulations, and improve operational efficiency. Our LDAR approach includes:
- Scope and plan inspections safely based on your priorities and regulatory requirements.
- Detect leaks with advanced OGI technology
- Classify leak source and location
- Quantify emissions via Hi Flow meter
- Coordinate with site operations and maintenance on repairs
- Verify repairs with OGI
What standards do SLB LDAR surveys support?
Programs are configured to applicable LDAR regulations and site requirements.
How often should we survey?
Frequency depends on regulation, risk profile, and site changes; we recommend baseline + periodic follow-ups.
Do you provide quantification?
Yes—quantification supports prioritization and reporting.
Can you cover multi-site programs?
Yes—our team scales routes and reporting across facilities.
