ABSTRACT

Detecting natural gas leaks from the worlds nearly 5 million kilometers of underground pipelines is a difficult and costly problem. Existing technologies are limited to ground deployment and have a number of limitations such as slow response, false leak readings and high costs. Various remote sensing solutions have been proposed in the past and a few are currently being developed. This paper starts by describing the remote sensing concept and then will focus on a new technology called realSensTM. This airborne instrument is a passive Gas Filter Correlation Radiometer that is tuned to measure ethane in the 3.3 microns near-infrared band. With its target natural gas column sensitivity of 50 0m, the instrument is capable of detecting very small leaks in the range of 5 – 10 cuft/hr in winds that exceed 6 miles/hr. The paper concludes with a description of the service which Synodon will be offering to the transmission and distribution pipeline operators using the realSensTM technology.
