CSG leaks "equal to that of cows"

Leaking methane from coal-seam gas wells was not as high as feared, with each well emitting about the same as four cows, a CSIRO study has found.

A review of 43 CSG well sites in Queensland and NSW undertaken for the federal environment department found leaking from the Australian industry was much lower than in the US.

All of the methane leaks were from equipment and none due to the release of gas from outside of the well casing. The worst leaks were from well sites that were under pressure after being put out of production.
