Huge oil reserves in southern England, report to say Huge oil reserves in southern England, report to say

A government report estimating that there are several billion barrels of oil in shale rocks under large parts of southern England is to be published on Friday, the BBC understands. A report published on Friday is expected to say that there are several billion barrels of oil in shale rocks under large parts of southern England.
The report, by the British Geological Survey (BGS), covers parts of Sussex, Hampshire and Kent. But getting the oil out of the ground will involve the controversial process known as fracking.
Getting it out of the ground will involve the controversial process known as fracking. The study by the British Geological Survey (BGS) covers areas including Sussex, Hampshire, Surrey and Kent.
Only a fraction of the total is thought likely to be ultimately recovered. The government is planning to offer more compensation for towns affected by fracking, according to press reports.
It is understood the report will say that there are several billions barrels of oil in place. The BBC's John Moylan said that although the BGS study will say that there are several billion barrels of oil in place, is not clear how much would be economically recoverable.
But he said the report's estimates could still have implications for the UK's long-term energy security and kick-off a drive to start fracking for oil in the region.
By way of comparison, the equivalent of around 45 billion barrels of oil has been extracted from the North Sea over the past 40 years.By way of comparison, the equivalent of around 45 billion barrels of oil has been extracted from the North Sea over the past 40 years.
The BBC's John Moylan said that although there are vast quantities of shale oil and gas in the UK, it is not clear how much would be economically recoverable.
But he said this new estimate could have implications for the UK's long-term energy security and kick-off a drive to start fracking for oil in the region.
Last year, a BGS study of the North of England suggested there could be as much as 1,300 trillion cubic feet of gas contained in shale rocks.Last year, a BGS study of the North of England suggested there could be as much as 1,300 trillion cubic feet of gas contained in shale rocks.
The fracking process involves pumping water, sand and chemicals into rock at high pressure, and it has sparked demonstrations by environmentalists. Some governments have banned the process.The fracking process involves pumping water, sand and chemicals into rock at high pressure, and it has sparked demonstrations by environmentalists.

Critics argue that the fracking process damages water supplies and can cause earthquakes. Critics argue that fracking damages water supplies and can cause earthquakes. There have been strong anti-fracking protests at Balcombe, West Sussex, against test-drilling.
In the US, fracking has created an energy boom and led to speculation that the country could overtake Saudi Arabia as the world's biggest oil producer by 2020 or even sooner. However, a government report published in June 2012 concluded that fracking was safe if adequately monitored.
Politically sensitive
Prime Minister David Cameron has insisted fracking will be "good for our country" and has blamed a "lack of understanding" of the process for some of the opposition.
There were media reports on Friday that the government will release details of additional compensation arrangements for communities affected by fracking, in order to stave off opposition. There have already been promises of one-off payments and a share in the profits.
The fracking issue is also politically sensitive. Tory peer Lord Howell of Guildford - who apologised last year after saying that fracking should take place in the North East because it was "desolate" - recently spoke about the issue again, and said the Conservative Party could lose votes by pursuing plans to frack.
The counties covered by the BGS survey are considered strong Tory territory.
For many years, there been more traditional exploration and development of oil and gas in the region.
Andrew Austin, chief executive of the onshore energy IGAS, said it had long been known that southern England had extensive resources.
He told the BBC: "We've known that there's a big potential for oil and gas explorations across the country but particularly in terms of oil in the Weald Basin which is the area that stretches roughly from Winchester across towards Gatwick, up to the M25 and down to the coast at Chichester.
"There's been a long history of oil and gas exploration in this area. We as a company produce oil and gas from around 20 sites across that area. Around 40 million barrels have been recovered from that area to date."
