FLIR Systems: Quantifying Methane Leaks & Flares from Oil & Gas Operations
hits:140     Date:01/29/19

FLIR Systems reports on how its GF-Series Optical Gas Imaging (OGI) cameras can be used by the oil and gas industry to quantitatively measure methane emissions and create a datum point for future methane reduction calculations.

Traditionally gas has been flared when it arrives as an unwanted part of an oil production stream. Where regulations permit, flaring gas has long been viewed the easiest way to handle this problem. However, gas flaring is damaging for environmental reasons resulting from emission of Carbon Dioxide and unburnt methane and also risk to health from hydrocarbon liquids and particulate matter entering the atmosphere. As a result, many oil companies are making efforts to get a better handle on both flares and emissions, to try to demonstrate that gas is a cleaner fuel than coal.

Over the last decade - OGI cameras have been widely used in the oil and gas industry to help find leaks. Traditionally their use was usually followed up with other methods, such as sniffers and ultrasonic devices, to assess the size of the leak. 

FLIR Systems, in partnership with Providence Photonics, has developed new Quantitative Optical Gas Imaging (qOGI) technology, which is designed to work exclusively with FLIR GF-Series OGI cameras. Quantitative OGI represents a critical step forward in the world of optical gas imaging because it eliminates the need for secondary sampling devices to quantify gas emissions.

This new quantification technology measures the 2D size of an emitted gas plume, and does a calculation to estimate the volume of the plume in space. Then it uses other data and modelling algorithms to estimate how fast the plume is dispersing into the atmosphere (and by inference how fast gas is going into the plume). By using Providence Photonics鈥 QL320™ in conjunction with a FLIR GFx320 or FLIR GF320 OGI camera, oil and gas producers can now measure mass leak rates or volumetric leak rates for most hydrocarbons including methane.

Methane leaks from oil production gas flaring can be visualized using the new FLIR qOGI technology at distances of up to 100 feet (33 meters) as long as you鈥檝e got line of sight. According to a recent study by CONCAWE (the European Oil Company Organization for Environment, Health and Safety), qOGI technology has a 6 per cent error rate on average, while a traditional sniffer had a 31 per cent error rate. This testing was done at the National Physical Laboratory (UK).
