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. 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.

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. It enables:
 

  • Real-time image capture and tagging

  • Synchronized data entry across sites

  • Secure mobile and web access

  • Simplified reporting and regulatory documentation
     

This all-in-one system eliminates manual processes and fragmented tools, giving clients a centralized, efficient solution for emissions management.
