The Resolution Disconnect: Legacy OGI vs Modern Orbital EnforcementThe “Blind Spot” of Early OGI When OOOOa was drafted, the imaging requirements were broad and did not specify strict thermal sensitivity benchmarks (NETD). As a result, many LDAR teams deployed first-generation infrared cameras with NETD around 25 mK to 30 mK. ...

Technologies referenced by the IEA include LDAR systems, vapor recovery systems, flare gas recovery, and ventilation air methane (VAM) oxidation technologies. ...
Transitioning from OOOOa to a Space-Aware Strategy LDAR workflows built for earlier regulatory regimes must evolve. Key elements include: Hardware Maturity: Ensure every methane detection camera in the fleet meets NETD under 10 mK to detect small leaks that satellites may aggregate. ...

It targeted affected facilities constructed after September 2015, including well completions, centrifugal compressors, reciprocating compressors, and pneumatic controllers. For LDAR, it mandated semi-annual OGI surveys for well sites and quarterly surveys for compressor stations. Why OOOOa is No Longer Sufficient The Existing Source Loophole: legacy assets built before 2015 ...

In the high-stakes methane mitigation environment, the effectiveness of LDAR hinges on skilled operators and certified procedures. As regulatory enforcement under EPA Appendix K intensifies, the industry is transitioning from point-and-shoot detection to standardized, high-precision practice. This overview emphasizes OGI certification, CH4 plume science, and camera technology as ...

EPA OOOOb/c standards for new sources and OOOOc for existing sources, alongside stringent European methane regulations, drive a shift from voluntary leak detection to mandatory, quantitative LDAR. Operators and field engineers must determine the required level of OGI sensitivity to comply and preserve profitability.The Regulatory Perfect Storm: From OOOOa to the OOOOb/c EraFor ...

ByOPGAL
The EPA continues to accelerate its methane reduction strategy by tightening performance standards across the petroleum and natural gas sector. Two major components of this regulatory shift are OOOOb and OOOOc, each addressing different stages of industry activity. While operators are becoming familiar with the OOOOb summary that outlines requirements for new, modified, and reconstructed sources, ...

Introduction: Why Camera Leak Detection Matters Gas leaks pose significant safety, environmental, and financial risks. Methane and other volatile compounds are invisible to the naked eye, but even small leaks can lead to catastrophic accidents, regulatory fines, and lost revenue. For decades, industries relied on handheld sensors that could only measure one point at a time. Today, a camera leak ...
