Oil-spill partner wins Wellington prospect

One of the partners in the Deepwater Horizon oil-spill disaster hopes to be drilling south of Wellington in five to seven years.

But the Green Party and environmental groups warn that, if anything were to go wrong, it could be months before an oil spill could be stopped.

Two exploration permits for adjoining blocks in the Pegasus Basin off the Wellington and Wairarapa coasts have been awarded to United States oil exploration and production giant Anadarko, a 25 per cent partner in the Deepwater Horizon project in the Gulf of Mexico.

An explosion on the rig in April 2010 killed 11 crewmen, and caused the biggest offshore oil spill in US history.

"It's outrageous the Government awarded deepsea oil drilling permits to the very company that was partially responsible for the catastrophic Gulf of Mexico oil spill," Greens energy spokesman Gareth Hughes said yesterday.

He claimed all of Anadarko's profits would go overseas, and the New Zealand public would "pay dearly if anything goes wrong".

However, Anadarko said it was not the operator of the Gulf of Mexico well, and in 20 years of deepwater drilling it had never had a significant incident.

The Government awarded 10 exploration permits yesterday, mainly in onshore and offshore Taranaki, as well as the new Pegasus Basin.

Last week, Brazilian oil giant Petrobras walked away from New Zealand after spending millions on a fruitless search for oil and gas in deep water off East Cape.

Even if a well were to be sunk in the Pegasus Basin, it could be at least five years away, at a cost of up to $100 million.

If exploration was successful, the Government could take up to 45 per cent of the profit in royalties and taxes.

Anadarko is hoping to find about 150 million barrels of oil. Its drilling rigs could be as close as 25 kilometres from shore, or up to 100km away.

The Gulf of Mexico disaster cost the US economy more than US$40 billion (NZ$47.8b) and caused an area twice the size of the North Island to be closed to fishing for months, Greenpeace says.

"Such an impact on New Zealand's fishing and tourism industries would cripple the country and destroy [its] clean and green international reputation," said its NZ climate campaigner, Simon Boxer.

John Gordon, Anadarko exploration manager, Asia Pacific, said the company had been a passive investor in the BP well. "At no time did Anadarko have any input or say in the operation of the well in the planning or execution."

It settled with BP by paying it US$4b, though there was no legal ruling which forced that.

Asked what assurance it could give about drilling in deep water, Mr Gordon said: "Anadarko has been doing the same for 20 years. We have done so with a very successful safety record and without a major incident in that time."

Neither Wellington City Council nor Greater Wellington regional council was consulted about the exploration permit, but iwi groups were.

PEGASUS BASIN

 

Covers an unexplored area of 25,000 to 50,000 square kilometres, with water depths from less than 200m to 3000m.

Thought to be rich in gas and gas hydrates, but also oil.

GNS Science petroleum scientist Kyle Bland says there is good evidence of oil reserves, but seismic data was insufficient to give a meaningful indication.

The basin's rocks are thought to be similar to those of the neighbouring East Coast Basin, an area with known natural oil seeps and a history of exploration and offshore drilling.

What effect will a potential ban on booze at Rugby Sevens 2015 have on you?

I'd no longer go ... what's the point?

I'd buy a ticket, with rugby the priority again.

Ban or no ban, I'm still going.

I'd rather watch 'Wheel of Fortune' on a 24/7 loop than 7s.
