What is LDAR software?
LDAR software helps teams manage the field workflows and records involved in Leak Detection and Repair programs. Depending on the platform and program, it can support:
The software may also connect field activity with environmental, maintenance, asset, and enterprise systems.
The detection technology itself can vary. LDAR programs may use optical gas imaging (OGI), Method 21, audio-visual-olfactory (AVO) inspections, or other approved methods. Software helps teams manage the workflow and evidence around those activities.
Leak Detection and Repair (LDAR) programs help oil and gas operators identify, document, repair, and verify fugitive emissions.
The work starts in the field, where technicians inspect equipment and record their findings. It continues through repair assignments, follow-up checks, recordkeeping, and reporting.
LDAR software helps connect those steps.
A digital workflow can give technicians the right inspection process, equipment information, and documentation requirements at the point of work. It can also move completed records to the teams and systems responsible for repairs, environmental reporting, and program oversight.
This guide explains how LDAR programs work in the field, what current EPA rules mean for field operations, and what to evaluate in LDAR software.
What does LDAR stand for in oil and gas?
LDAR stands for Leak Detection and Repair.
In oil and gas operations, LDAR programs identify fugitive emissions from equipment and track responses.
Those emissions can include methane and volatile organic compounds (VOCs) released from valves, connectors, pumps, compressors, and other equipment.
An LDAR program typically connects monitoring with documentation, repair activity, follow-up checks, and required records.
How EPA OOOOb and OOOOc affect LDAR program management
Oil and gas LDAR programs may be subject to federal, state, and site-specific requirements.
As of September 2026, EPA is continuing a broader reconsideration of the OOOOb and OOOOc framework. The agency also finalized revisions to two narrow technical provisions in April 2026.
Organizations should confirm current requirements with their environmental, regulatory, or legal teams before changing an LDAR program.
What is OOOOb?
EPA’s NSPS OOOOb establishes New Source Performance Standards for applicable new, modified, and reconstructed oil and natural gas sources.
The rule includes requirements related to methane and VOC emissions, including fugitive-emissions monitoring for covered equipment and facilities.
Monitoring methods, schedules, repair requirements, and recordkeeping can vary by source and applicable provisions.
You can review the latest information on EPA’s oil and natural gas regulations.
What is OOOOc?
OOOOc establishes Emissions Guidelines for states to use when developing plans for covered existing oil and natural gas sources.
EPA explains that the guidelines provide the framework for state plans. Requirements for individual existing sources depend on the applicable approved plan and other governing rules.
That makes current regulatory review essential when designing or updating a field workflow.
What do these rules mean for field LDAR workflows?
Regulatory requirements can affect how technicians inspect equipment and what they need to record afterward. An LDAR workflow may need to account for:
- The monitoring method used
- Inspection frequency and scheduling
- Facility and component information
- Leak findings and supporting evidence
- Repair attempts and repair status
- Follow-up or verification checks
- Exceptions or delay-of-repair records, when applicable
- Technician and inspection details
- Recordkeeping and reporting data
Those requirements can change. A configurable field workflow gives operations teams more control when inspection steps, documentation requirements, or reporting needs change.
How an LDAR program works in the field
Leak detection is one stage of a larger process.
A complete LDAR workflow needs to carry the finding through repair, verification, and final documentation.

Where manual LDAR workflows create problems
Paper forms and spreadsheets can work for individual inspections. Problems grow as facilities, components, technicians, and repair records accumulate.
Field teams may deal with damaged forms, difficult handwriting, and repeated data entry.
Information can also sit in a truck, inbox, or spreadsheet before someone else sees it.
That delay becomes more important after a leak is identified.
Someone needs to know what was found, where it occurred, who owns the repair, and whether verification is still required.
Manual handoffs make that history harder to follow.
They can also create extra administrative work when teams need to prepare records for internal reviews, reporting, or audits.
A digital workflow keeps inspection, repair, and verification information connected from the point of capture.
What to look for in LDAR software
The right software should fit how your LDAR program operates in the field. Use these criteria when evaluating your options.
| Capability | What to evaluate |
|---|---|
Mobile field use |
Can technicians complete monitoring and document findings while working at the asset? |
Offline capability |
Can required work continue at remote sites or facilities with unreliable connectivity? |
Configurable workflows |
Can your team update inspection steps, questions, validation rules, and follow-up processes as requirements change? |
Asset and component records |
Can technicians access the correct facility, equipment, and component context during the inspection? |
Repair tracking |
Can an identified leak move into assigned repair work and remain visible through verification? |
Evidence and audit history |
Can teams retain photos, timestamps, geolocation, technician identity, signatures, and record changes? |
Integrations |
Can LDAR records connect with EAM, FSM, ERP, environmental, or reporting systems? |
Reporting and analytics |
Can teams quickly find open findings, repair status, exceptions, trends, and supporting records? |
Key point
Also consider who owns the workflow.
Environmental requirements, inspection procedures, and internal standards can change. Operations teams should be able to update field processes without starting a lengthy development project.
How TrueContext supports LDAR workflows
We help oil and gas teams connect LDAR field work with the systems and people responsible for the next step.
Our guided field workflows can walk technicians through required inspection steps using conditional logic, validation, required fields, and field guidance.
You can load existing facility, asset, or component information into the workflow before technicians begin.
That gives the field team useful context without asking them to enter the same information again. Technicians can document findings with:
- Photos and sketches
- Barcode or QR scans
- GPS information
- Timestamps
- Digital signatures
- Measurements and field responses
- Supporting notes and documents
Work can also continue when connectivity is limited.
TrueContext’s mobile workflows support offline field execution. Completed records synchronize after a connection becomes available.
Once the technician submits the workflow, that information can move into other business systems.
Our enterprise integrations can exchange data with platforms used for field service, assets, customers, maintenance, and reporting.
LDAR records can also retain the supporting history needed for internal reviews and audit preparation.
TrueContext audit trails can capture information such as users, timestamps, geolocation, submission versions, and image metadata.
Teams can then use reporting and analytics to review field activity, open issues, trends, and completed work.
These capabilities support LDAR field execution and documentation. Regulatory requirements should still be reviewed with the appropriate environmental and compliance teams.
Outcomes of a connected LDAR workflow
Connecting the field finding with repair and verification gives teams a clearer record of the full process.
Improve asset uptime
Leak findings can reveal equipment conditions that also require maintenance attention.
Connecting inspection information with repair workflows helps maintenance teams respond earlier and build better asset histories.
That information can also support maintenance and repair workflows beyond the LDAR program.
Support worker and site safety
A documented field workflow gives operations teams faster visibility into identified conditions and required follow-up.
Technicians can also receive required instructions and capture supporting evidence while they are still at the site.
Reduce field and administrative work
Digital field records reduce the need to copy inspection information from paper into another system.
Automated reports and system connections can also reduce repeated handoffs between technicians, environmental teams, maintenance teams, and administrators.
Strengthen compliance records
Structured records make inspection, repair, and verification history easier to retrieve.
Photos, timestamps, technician attribution, signatures, and record histories can provide additional context when teams prepare documentation for review.
