Methane Leak Detection for Oil & Gas Facilities
Locate suspected leak sources, verify CH4 in the field, and monitor high-risk gas wells, valve groups and pipeline stations with a combined handheld inspection and fixed acoustic monitoring solution.
One application, two working modes
Methane leaks are often small, intermittent and hard to confirm.
Methane leaks often happen around valves, flanges, wellheads, compressor areas and pipeline facilities. Some leaks are small, some are intermittent, and some are located in places where manual inspection is difficult or unsafe.
For most oil and gas facilities, one method is not enough. Inspection teams need a handheld tool to find and confirm suspected leaks, while high-risk locations need fixed monitoring for early warning and remote alarm workflows.
- Find suspected leak points during field inspection.
- Verify CH4 concentration when methane evidence is needed.
- Monitor gas wells, valve groups and pipeline stations continuously.
- Support LDAR, maintenance records and site safety workflows.
Turn methane detection into a practical LDAR and safety workflow.
A useful methane leak detection page should not only introduce devices. It should show how the devices help operators discover, confirm, document and respond.
LDAR inspection
Support routine leak detection and repair routes with field images, CH4 readings and inspection evidence.
Maintenance decisions
Help technicians prioritize valves, flanges, seals and fittings that need repair or follow-up inspection.
Fixed early warning
Monitor gas wells, valve groups and remote stations where manual inspection frequency is limited.
Data integration
Send alarm data through 4G, Ethernet, HTTP, WebSocket or Modbus TCP to platform and SCADA workflows.
Typical methane leak detection sites
The same site may need both manual inspection and fixed monitoring. HA3LX is used for inspection rounds. HZ-WL-15A is installed at risk points that need continuous warning.
Gas wells and wellheads
Monitor wellheads, Christmas trees, gas outlets and surrounding pressure equipment.
Valves and flanges
Check valve gaps, flange seals, fittings and pressure control components.
Pipeline stations
Use fixed monitoring around metering stations, valve groups and pressure regulation areas.
LDAR routes
Use HA3LX to support leak detection and repair inspection records.
LNG and gas handling
Inspect LNG/CNG facilities, compressor areas and gas handling equipment.
Remote field sites
Use HZ-WL-15A where manual inspection is limited by distance, staffing or safety conditions.
Handheld inspection and fixed monitoring work together.
Position the solution as a layered deployment: mobile confirmation for inspection teams, and continuous alarm coverage for high-risk fixed points.
HA3LX for inspection teams
Use HA3LX during LDAR routes, plant inspection, LNG site checks and oil and gas maintenance work. It helps users locate the acoustic source first, then verify CH4 concentration with TDLAS.
- Walk-around methane inspection
- Gas leak acoustic localization
- TDLAS methane verification
- Inspection images and records
HZ-WL-15A for high-risk points
Use HZ-WL-15A where continuous manual inspection is not practical. It listens for leak-related sound signatures around gas wells, wellhead valves and pipeline stations, then sends alarms to a platform.
- Fixed acoustic monitoring
- Gas well and valve monitoring
- Edge AI local recognition
- 4G, Ethernet and Modbus TCP
Detect, locate, verify, record and alarm.
This replaces the repeated Workflow and How It Works sections with one clearer site workflow for buyers and search engines.
Detect
Capture audible or ultrasonic leak-related sound from pressurized components.
Locate
Use HA3LX acoustic imaging to show the suspected leak source on screen.
Verify
Use TDLAS methane detection to confirm CH4 evidence along the measurement path.
Record
Save images, videos, readings and inspection notes for maintenance follow-up.
Alarm
Use HZ-WL-15A to monitor fixed points and transmit remote leak alarms.
HA3LX Acoustic & Methane Laser Camera
HA3LX is for inspection teams who need to walk the site, check suspected leak points and keep inspection evidence. The camera combines acoustic imaging with TDLAS methane detection, so users can locate the leak-related sound source and verify whether methane is present along the measurement path.
HZ-WL-15A Gas Well & Valve Leak Monitor
HZ-WL-15A is for locations that need continuous attention but cannot rely only on manual inspection. It captures leak-related acoustic signatures around gas wells, wellhead valves and pipeline stations, analyzes the signal locally, and sends alarms through wired or wireless communication.

Common questions
Do I need both HA3LX and HZ-WL-15A?
Not always. Use HA3LX if your main task is field inspection or LDAR. Use HZ-WL-15A if you need continuous monitoring at fixed points such as gas wells, valves or pipeline stations. For high-risk sites, the two products can be used together.
Is HA3LX a methane detector or an acoustic camera?
It is both. HA3LX combines acoustic imaging with TDLAS methane detection, so it can help locate the suspected leak source and verify CH4 concentration.
Where should HZ-WL-15A be installed?
Typical locations include gas wells, wellhead valves, valve groups, pipeline stations and other fixed points where continuous leak monitoring is needed.
How does the solution support LDAR workflows?
HA3LX can be used during LDAR routes to locate suspected leak points, verify CH4 with TDLAS and keep field evidence for maintenance follow-up. HZ-WL-15A can add fixed early warning at high-risk points that need continuous monitoring.
Does acoustic methane detection replace OGI?
It is better to present acoustic imaging, TDLAS methane verification and OGI as complementary methods. Acoustic imaging helps locate leak-related sound sources, TDLAS verifies methane evidence, and OGI can visualize gas plumes under suitable field conditions.
