 Gas find under shire 

Gas find under shire

03 Dec, 2008 02:09 PM
SYDNEY Gas has found an estimated $10 billion worth of coal-seam methane gas under the Hunter Valley and some of that gas is under the Upper Hunter Shire between Scone and Merriwa.

Sydney Gas publicity officer Elizabeth Flaherty said Sydney Gas estimates they have found 25,000 petajoules (PJ) of coal methane gas under the Hunter Valley.

Ms Flaherty said they would continue to explore and assess the viability of the gas until 2011.

She said they may find they could only use 10,000 to 12,000 PJ.

But this was still a significant amount of gas considering the Sydney gas market has been supplied with 2000 PJ for 30 years.

Ms Flaherty was optimistic that Sydney Gas would find adequate gas reserves in the Upper Hunter and said the company was currently drilling a core hole near Gungal and another core hole had been approved for a site at Rossgole.

But Ms Flaherty said even if gas was found at these sites it would need to be tested for permeability as they could not use gas that had water in it.

The gas also could not be used if there was coal mining happening at the site of the gas reserves.

Ms Flaherty said because of this, some of the residents from the Upper Hunter who have been approached by Sydney Gas have welcomed the proposal because it would mean they would not have to contend with a coal mine should the gas well be built.

Gas wells are already in place and pumping gas at Camden and were about the size of a small shed and household water tank.

Controversial methane gas explorer, Sydney Gas Ltd., has failed to reveal that attempting to prove its yet unsupported claim of a $10bn methane gas reserve, will require drilling through water tables and aquifers which independent studies reveal would contaminate and diminish ground water, waterways and possibly the Hunter River. Sydney Gas, on behalf of itself and AGL, also proposes to drill for gas within 300 metres of the primary school in the Hunter vineyard Village of Broke and warns of the risk of explosion of this highly explosive gas. General Manager of Sydney Gas also warns of the risk of the migration of methane gas from its wells, which wouldn’t be detected for 2 years when vegetation, lawns and gardens, started to wither and die. Methane gas has already seeped from wells drilled in Stratford (Hunter Valley) in 2004 and was blowing off in water bores 300 metres away. The wells had to be shut down. Both Sydney Gas and the Director of Mineral Resources have independently stated: “that without community support there is no project”. Hunter Valley communities are as one in their vehement opposition to drilling through water tables, and drilling adjacent to towns and villages, so indeed there may well be no project to extract this gas, a gas in excess of 20 times more damaging as a greenhouse gas than CO2.

There is little Government regulation of the methane gas industry and this needs to be done before one more well is drilled.

Elizabeth, how do you test gas for permeability? Don't you test the coal for permeability? How is the permeability test related to the amount of water in the gas? Please provide evidence of your claims in this post in which you have clearly "drank the SGL kool-aid" of the Sydney Gas rhetoric but unfortunately put the words in the wrong order... just like your unfortunate claim of the eagles flying around the drill rigs. They were hunting the injured and distressed small mammals and reptiles that the drill vibration, noise and toxicity had disturbed! Is Hunter Valley Public Relations still engaged by Sydney gas following this huge strategic gaff?

Still no retraction or correction of the misleading and totally incorrect facts presented here by (NSW Labor Party contributor and 100% AGL Energy-owned) Sydney Gas "publicity officer Elizabeth Flaherty".
