Continuous LDAR Monitoring for Confident Compliance

LDAR stands for Leak Detection and Repair. It is a program used by oil and gas and industrial operators to find leaking components or fugitive emissions, document the findings, repair qualifying leaks, and verify the outcome. An LDAR program typically includes defined monitoring methods, inspection frequencies, repair timelines, records, and reporting procedures required by applicable regulations or company standards.

LDAR compliance means operating a leak detection and repair program in accordance with the rules that apply to a facility or asset. Requirements can address which equipment is monitored, approved detection methods, inspection frequency, repair deadlines, resurvey procedures, recordkeeping, and reporting. Continuous monitoring can supplement periodic surveys by creating time-stamped event records and supporting faster investigation of validated emissions events.

Periodic LDAR inspections provide a snapshot of site conditions on the day of the survey. Continuous LDAR monitoring observes conditions around the clock, allowing operators to identify events that occur between scheduled visits and understand their duration. Well Checked’s approach combines optical gas imaging, video, acoustic sensing, and AI validation to focus attention on likely fugitive anomalies rather than every normal operating event.

Yes. Long-wave infrared optical gas imaging is used to monitor methane and volatile organic compound emissions at applicable wellsite equipment. Detection performance depends on factors such as gas composition, release rate, distance, weather, equipment layout, and camera placement. A well-designed program should account for these site conditions while using additional sensor inputs and operational context to validate potential events.

False-alarm reduction begins with establishing normal site behavior. Zensory.ai™ uses an approximately two-day AI Site Learning cycle to recognize recurring visual, acoustic, and process-emissions patterns. Zentinal Core™ evaluates multiple sensor streams and can suppress known non-fugitive process events through site-specific tuning. This helps designated teams receive alerts for more meaningful anomalies instead of reacting to routine activity.

After Zentinal Core™ validates a potential fugitive event, the operator’s designated response team can receive a near-real-time notification through the Well Checked Dashboard, email, text, or SCADA. Dispatch runbooks can guide acknowledgement, field dispatch, mitigation, and documentation. The response process remains under the operator’s control, while the monitoring record provides context for investigation and repair decisions.

Yes. Well Checked offers SCADA integration services that deliver alerts, emissions data, and operational insights within existing control-room workflows. Integration planning should define the alert types, escalation rules, receiving systems, and responsible teams before deployment. This allows operators to use monitoring intelligence alongside familiar operational data rather than requiring personnel to manage an entirely separate response environment.

Well Checked structures emissions data to support EPA methane-rule alternative-monitoring compliance submissions under 40 CFR Part 60 Subpart OOOOb, where applicable. The data approach is also aligned with OGMP 2.0 Level 4/5 measurement-based reporting and can support SASB Oil & Gas E&P and TCFD disclosure frameworks. Operators remain responsible for determining the specific regulatory requirements that apply to their assets.
