Services / On-Site Testing / Fugitive Emissions / Optical Gas Imaging Optical Gas Imaging (OGI) See the Unseen Using Optical Precision OGI cameras are engineered to rapidly detect leaks with high-resolution imaging, enabling the visual identification of even the smallest gas leaks across many hundreds of components. EXPERIENCE Our certified OGI technicians, including licenced drone pilots and seasoned leaders, bring deep expertise and widespread coverage across the U.S. and Canada, with extensive field experience in optical gas imaging. EQUIPMENT We deploy a robust inventory of OGI cameras, drone-camera systems, and portable Method 21 VOC analyzers—supported by our cloud-based platform for efficient data reporting and management via web and mobile. PROJECTS & CLIENTS As a trusted LDAR partner, we serve oil and gas companies throughout North America, delivering proven results across a wide range of projects involving well pads, tanks, and pipeline infrastructure. OGI Services Optical Gas Imaging (OGI) is a game-changing technology that enables the visual detection of gas leaks in real time—quickly, safely, and with unparalleled accuracy. By identifying fugitive emissions at the source, OGI enhances operational safety, reduces environmental impact, and lowers compliance costs for industrial facilities. Alliance Technical Group offers industry-leading OGI services backed by a seasoned team, robust data systems, and a commitment to quality. Whether you operate upstream, midstream, or downstream, our nationwide team delivers high-performance leak detection where and when it matters most. Applications OGI is a flexible solution ideal for diverse industrial sectors and applications: Upstream: well pads, offshore rigs, crude storage Midstream: pipelines, gas terminals, compressor stations Downstream: refineries, above-ground storage tanks Other Sectors: gas utilities, biogas plants, landfills, mining, semiconductor manufacturing OGI is also effective for detecting emissions from compressor rod packing systems, which are a common source of methane leaks in reciprocating engines. By visualizing and pinpointing these leaks in real time, operators can take corrective action before emissions exceed regulatory thresholds or impact equipment performance. Learn More About Our Engine Testing Services What are the benefits of having an OGI camera program? Reduce product loss Increases safety for workers and operators Decreases hazardous exposure for the surrounding community Reduces or eliminates potential fees and fines Regulatory Coverage Our services are fully aligned with federal and state requirements, including: Subparts OOOOa, OOOOb, OOOOc Subpart W 40 CFR Part 60, Appendix K Alternative Work Practice (AWP) Regional standards like Rules 1173 & 1178 SkyBridge OGI Software SkyBridge is our proprietary, cloud-based platform designed to streamline leak detection workflows.

Learn More About the 6-3-1 Process Here's the rundown on our proven pre- to post-testing process that involves precise coordination and communication to ensure the best testing results. From start to finish, we stay in constant communication. Learn what happens at the major milestone stages of 6 weeks, 3 weeks and 1 week prior to testing. The 6-3-1 Process 6 Weeks Prior: Preparation Alliance will email test week details to pertinent parties to request information that is unknown and address questions about permit research that has been completed. We hold ourselves accountable to every last detail, because every detail matters. The following week we will prepare any testing notifications or protocols required by the regulatory agency(s) and continue our communication with pertinent parties. Expect our background work and 1:1 communications to continue until mid-way through the process when we will begin sharing details on how testing will be conducted. 3 Weeks Prior: Verification Successful stack testing takes a team approach. Getting the right information to the right people at the right time is our strength. Communicating what’s needed upfront saves time, improves quality and builds camaraderie, ensuring all parties feel connected and informed. At this stage, the full plan begins to come together - from the big picture to the small details. No guesses, no assumptions. We validate the facts and communicate them to ensure everyone involved understands exactly what’s needed, because no two stack tests are the same. 1 Week Prior: Confirmation One week prior to testing day, the Alliance Testing Technician will communicate directly with the customer site contact to confirm the meetup and kickoff schedule for the onsite testing. Additional emails with test week details will be sent to all pertinent parties to ensure there are no surprises. And, if there is a need to adjust to new information or emergent insights, we will adapt accordingly, keeping everyone informed along the way.
