Gas Industry Repeats Attack On Scientists Who Found Triple Methane Levels At Gas Fields

In August 2012, two Australian research scientists attached a highly sensitive spectrometer to a vehicle with a GPS tracker and took a 700 kilometre drive around gas fields in Queensland.

Starting at 3.30am in the morning, Dr Isaac Santos and Dr Damien Maher, of Southern Cross University, wanted to measure the levels of methane and carbon dioxide in the air around coal seam gas fields operated by BG Group, formerly known as British Gas.

Twelve hours of driving took them past fields with about 300 wells that tap coal seams to release gas, often with the help of hydraulic fracturing (fracking) technology.

They also drove past other areas where you might expect levels of methane to be high such as wetlands, fields of cows and sewage treatment plants.

The researchers found methane levels at the gas fields were triple the background levels.

The chemical fingerprints of the methane they detected near the gasfields — known as isotopic signatures — matched those from the gas produced from the wells.

Gas Industry Attacks Scientists After Research Finds Triple The Normal Levels Of Methane At Australian Gas Fields

LEVELS of the potent greenhouse gas methane have been recorded at more than three times their normal background levels at coal seam gas fields in Australia, raising questions about the true climate change impact of the booming industry.

The findings, which have been submitted both for peer review and to the Federal Department of Climate Change, also raise doubts about how much the export-driven coal seam gas (CSG) industry should pay under the country's carbon price laws.

Southern Cross University (SCU) researchers Dr Isaac Santos and Dr Damien Maher used a hi-tech measuring device attached to a vehicle to compare levels of methane in the air at different locations in southern Queensland and northern New South Wales. The gas industry was quick to attack their findings and the scientists themselves.

The Queensland government has already approved several major multi-billion dollar CSG projects worth more than $60 billion, all of which are focussed on converting the gas to export-friendly liquefied natural gas (LNG).

More than 30,000 gas wells will be drilled in the state in the coming decades and the industry has estimated between 10 per cent and 40 per cent of the wells will undergo hydraulic fracturing.
