Benefits of Using Gas Cloud Imaging Technology to Detect Leaks on Gas Pipelines

Abstract

Managing the integrity of pipeline system and gas process facilities is the primary goal of every gas field operator, particularly in sour gas operations. This document presents the benefits of utilizing Gas Cloud Imaging (GCI) technology to detect leaks on gas pipelines. It introduces the unique sequence of this sour gas operation and pipeline infrastructure layout that introduces challenges in achieving safe and reliable delivery of natural gas to their customers without adverse effects on the public, customers, employees, or the environment. It provides informative methodology and principles regarding infrared absorption spectroscopy and hyperspectral infrared imaging. The paper also shares how the detection capability and operational feasibility are proven through a field pilot implementation. It further introduces how the operator designs the GCI technology applicable to the entire pipeline route and combines with gas point detectors to achieve full detection coverage. Finally, it makes recommendations how to make the technology benefit a wider range of usage in oil and gas industry to improve safety and a reduction in the number of incidents.
