About
LongPath Technologies is an industrial emissions monitoring company built on more than a decade of R&D, specializing in continuous, site-wide methane monitoring for the oil and gas sector. Their platform is anchored by proprietary laser line sensor technology that provides superior accuracy and comprehensive spatial coverage across entire facilities — eliminating gaps common in point-sensor or periodic inspection approaches. The solution operates with 99% uptime, delivering real-time, actionable emissions data without noise or guesswork. LongPath handles installation, calibration, maintenance, and ongoing monitoring as a fully managed, white-glove service, freeing operator teams to focus on production. The platform is trusted by major Permian Basin operators and is formally approved under EPA OOOO as well as state regulatory programs in California, Colorado, New Mexico, and Texas. It supports OGMP reporting, Subpart W greenhouse gas reporting, Waste Emissions Charge (WEC) compliance, and LDAR programs. Using the DIME framework — Detect, Identify, Measure, Eliminate — LongPath helps operators reduce leak cycle times, capture lost gas revenue (one operator reported $3.5 million in recovered gas value), and build future-proofed methane management portfolios. The company has secured a $162 million U.S. Department of Energy loan to expand its continuous monitoring network across major oil and gas regions. Ideal for enterprise E&P operators, midstream companies, and any organization facing federal or state methane regulations, LongPath turns compliance obligations into operational value.
Key Features
- Patented Laser Line Sensor Technology: Proprietary laser-based sensors provide site-wide spatial coverage and superior measurement accuracy, outperforming traditional point sensors or periodic surveys.
- 99% Uptime Continuous Monitoring: Always-on emissions detection delivers reliable, real-time data 24/7 without gaps, downtime, or reliance on manual inspections.
- Regulator-Approved Compliance: Formally approved under EPA OOOO and state programs in California, Colorado, New Mexico, and Texas, supporting OGMP, GHGRP Subpart W, WEC, and LDAR obligations.
- Turnkey White-Glove Deployment: LongPath manages the full lifecycle — installation, calibration, maintenance, and monitoring — as a fully managed service so operators can focus on production.
- Actionable Emissions Intelligence: Quantified, high-integrity data supports the DIME framework (Detect, Identify, Measure, Eliminate) to reduce leak cycle times and capture lost gas revenue.
Use Cases
- Large E&P operators in the Permian Basin or other major basins needing asset-wide continuous methane monitoring to meet EPA OOOO requirements
- Oil and gas companies building OGMP Level 4/5 emissions inventories that require site-level quantification data
- Operators subject to state methane regulations in California, Colorado, New Mexico, or Texas seeking regulator-accepted monitoring solutions
- Midstream and upstream companies looking to reduce methane leak cycle times and recover lost gas revenue through early, continuous detection
- Environmental, health, and safety teams managing Greenhouse Gas Reporting Program (GHGRP) Subpart W and Waste Emissions Charge (WEC) compliance obligations
Pros
- Proven Regulatory Acceptance: Approved by federal and multiple state regulators, reducing compliance risk and simplifying reporting across EPA and state methane programs.
- Demonstrated ROI: Operators report millions in recovered gas value and reduced leak response times, turning a compliance cost into a revenue-positive outcome.
- Fully Managed Service: The turnkey deployment and white-glove support model eliminates the need for operators to build in-house monitoring expertise or manage hardware.
- Enterprise-Scale Coverage: Deployed across 1.5+ million acres and 1,600+ sites in the Permian Basin alone, demonstrating proven scalability for large asset portfolios.
Cons
- Enterprise-Only Scope: The platform is designed for large oil and gas operators; it is not suited for small producers or non-industrial use cases.
- Opaque Pricing: Pricing is not publicly disclosed and requires direct engagement, making it difficult to evaluate costs without a sales conversation.
- Physical Hardware Deployment Required: As a hardware-plus-software solution, deployment involves on-site sensor installation, which requires lead time and site coordination.
Frequently Asked Questions
What regulatory programs is LongPath approved for?
LongPath is approved under EPA OOOO and state-level programs in California, Colorado, New Mexico, and Texas. Their data also supports OGMP, GHGRP Subpart W, and Waste Emissions Charge (WEC) reporting.
How does LongPath's laser line sensor technology work?
LongPath uses patented laser line sensors that beam across a facility to measure methane concentrations along the entire line path, providing spatial coverage and quantification accuracy that point sensors or drone surveys cannot match.
Is LongPath a managed service or a software platform?
LongPath is a fully turnkey, managed service. They handle installation, calibration, maintenance, and ongoing monitoring so operators receive clean data without managing hardware or personnel.
What is the typical uptime and reliability of the system?
LongPath's platform achieves 99% uptime, providing continuous 24/7 methane monitoring with minimal gaps or downtime.
How has LongPath been funded and validated?
LongPath has received a $162 million U.S. Department of Energy loan to expand its monitoring network and has been deployed by multiple top-10 Permian Basin operators, validating both its technology and commercial scale.
