Advanced optical gas imaging (OGI) services for leak detection. Real-time monitoring, regulatory compliance & improved operational safety solutions. 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 licensed 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.
