ECONOMICS REPORT - In the US, the New Look of Gas Exploration

2009 10 23 VOA 经济报道 美国天然气勘探新貌

This is the VOA Special English Economics Report.
这里是 VOA 特别英语的经济报道

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water. But it also leads to a fossil fuel. Natural gas is considered the cleanest of the fossil fuels, the fuels created by plant and animal remains over millions of years.

许多人认为清洁能源的探索仅仅是指可再生资源,如太阳能、风能和水能,但是也可以是化石燃料。天然气是最清洁的化石燃料,它是植物与动物残余经过数百万年后所产生的燃料。

Burning it releases fewer pollutants than oil or coal. The gas is mainly methane. It produces half the carbon dioxide of other fossil fuels. So it may help cut the production of carbon gases linked to climate change.

天然气的燃烧释放出的污染物比石油或煤少。天然气主要(组份)是甲烷,其(燃烧时)产生其它化石燃料的一半二氧化碳。因此,天然气有助于减少气候变化相关的二氧化碳排放。

Russia is first in what are called "proved reserves" of natural gas. The United States is sixth. Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America. They drilled straight down into formations where gas collects. As these supplies were used up, big drillers looked for similar formations in other countries.

俄罗斯位列“探明”天然气贮量第一,美国第六。多年来,大型油气公司开采了美国易开采的大部分天然气。他们直接向下钻到天然气聚集的构造之处。由于贮量已用尽,大型钻井设备在其它国家寻找类似的构造。

But now the industry is taking a new look. Companies are developing gas supplies trapped in shale rock two to three thousand meters underground. They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock.

但是,目前业界有了新貌。许多公司勘探地下 2 - 3 千米聚集天然气的页岩。他们钻到页岩,然后向侧面钻,并将高压水、砂或其它材料喷射入岩石。

This causes the rock to break, or fracture, releasing the gas. Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states.

这造成岩石破裂或开裂,释放出天然气。据称,大型天然气页岩位于阿巴拉契亚山脉、密歇根州以及中南各州。 

Gas shale exploration is being done mainly by small to medium sized companies.

天然气页岩勘探目前主要由小中型公司进行。

Eric Potter is a program director in the Bureau of Economic Geology at the University of Texas at Austin.

埃立克 . 波特 是 德克萨斯大学奥斯汀分校经济地质局的项目总监。

ERIC POTTER: "The types of opportunities that are left for natural gas exploration in the U.S. have changed. So it's a different class of resource -- not as easy to develop, and not even recognized as something worth pursuing, say, twenty years ago."

埃立克 . 波特:“美国天然气勘探的机会已经改变。因此,这是不同类型的资源,即不易勘探,甚至在 20 年前被认为不值得探寻的资源。”

He says more than half the gas in the United States is now coming from these new reserves.

他说,目前美国一半以上的天然气来自于这类贮量。

But hydraulic fracturing can also produce debate and anger over the risk of groundwater pollution. This method of drilling is not federally supervised under the Safe Drinking Water Act. Some in Congress want to end that exemption from the law.

但是,水力压裂也可导致对地下水污染风险的争议以及愤怒。这种钻井方法在安全饮水法案中未受到联邦监督。某些国会成员希望终止其法律豁免。

Natural gas provides Americans with about one-fourth of their energy. And, unlike oil, most of it is produced in America. Gas producers invested heavily in reaching new supplies when prices were high. But prices are down sharply now because the recession cut demand for energy. So energy expert Eric Potter says it is too early to know how the new gas shale reserves will affect the market.

天然气向美国人提供了大约四分之一的能源。另外,与石油不同,大部分天然气在美国开采。当价格高时,天然气开采公司大量投资,寻求新的天然气。但是,由于经济衰退减少了能源需求,价格急剧下降。因此,能源专家埃立克 . 波特说,想知道天然气新页岩贮量对市场的影响为时尚早。

经济报导 - 美国 , 天然气勘探新面目

Broadcast date: 10-23-2009 / Written by Mario Ritter

From http://www.unsv.com/voanews/specialenglish/

This is the VOA Special English Economics Report.

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water. But it also leads to a fossil fuel. Natural gas is considered the cleanest of the fossil fuels, the fuels created by plant and animal remains over millions of years.

谈到环保能源的开发时 , 多数人只想到可重复利用的能源 , 如太阳能 , 风能和水能 . 其实这也包括化石燃料 . 天然气被认为是最清洁的化石燃料 , 这种燃料是由植物和动物遗体经过上百万年的时间形成的 .

Burning it releases fewer pollutants than oil or coal. The gas is mainly methane. It produces half the carbon dioxide of other fossil fuels. So it may help cut the production of carbon gases linked to climate change.

它的燃烧释放的污染物质要比油或煤少 . 天然气的主要部分是甲烷 , 它产生的二氧化碳的量只有其它化学燃料的一半 , 所以这有助于减少导致气候变化的碳化气的产量 .

Russia is first in what are called "proved reserves" of natural gas. The United States is sixth. Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America.

在天然气的 ” 已探明矿藏量 ” 方面 , 俄罗斯位居第一 , 美国第六 . 多年来 , 大的油气公司恢复开采了大量容易开采的天然气源 .

They drilled straight down into formations where gas collects. As these supplies were used up, big drillers looked for similar formations in other countries.

他们直接打孔到有天然气的地层 , 这些资源用完时 , 大的施工队就去其他国家寻找相似的地层 .

But now the industry is taking a new look. Companies are developing gas supplies trapped in shale rock two to three thousand meters underground. They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock.

但是现在这个产业换了新面貌 . 众公司正在开发地下两三千米之遥的页岩中的天然气源 . 他们打孔到页岩地层 , 然后斜方向施工 , 并向岩石中注入高压水 , 沙 , 或者其他材质 .

This causes the rock to break, or fracture, releasing the gas. Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the southcentral states.

岩石会因此变碎或变脆 , 从而释放天然气 . 大面积的天然气页岩聚集在 阿巴拉契亚山脉 , 密西根州和中南部的各州 .

Gas shale exploration is be ing done mainly by small to medium sized companies.

Eric Potter is a program director in the Bureau of Economic Geology at the University of Texas at Austin.

一些中小规模的公司在做天然气页岩的勘探 . 埃里克 . 波特是奥斯汀德克萨斯州大学经济地质学机构的项目经理 .

ERIC POTTER: "The types of opportunities that are left for natural gas exploration in the U.S. have changed. So it's a different class of resource -- not as easy to develop, and not even recognized as something worth pursuing, say, twenty years ago."

埃里克 . 波特 :” 美国天然气开发的机会类型已经变了 , 所以这是个不同种类的资源 — 不容易开发 , 甚至被认为不值得开发 , 我是指 ,20 年以前 ”

He says more than half the gas in the United States is now coming from these new reserves. But hydraulic fracturing can also produce debate and anger over the risk of groundwater pollution.

他指出 , 现在的美国用气 , 一半以上都是出自这种新储备 . 但是由于存在地下水污染的风险 , 水力压裂仍然会引起争论和愤怒 .

This method of drilling is not federally supervised under the Safe Drinking Water Act. Some in Congress want to end that exemption from the law.

钻孔法在安全饮水法案中不受联邦监管 . 国会中有人提出想结束这种法律上的豁免权 .

Natural gas provides Americans with about one-fourth of their energy. And, unlike oil, most of it is produced in America. Gas producers invested heavily in reaching new supplies when prices were high. But prices are down sharply now because the recession cut demand for energy. So energy expert Eric Potter says it is too early to know how the new gas shale reserves will affect the market.

天然气为美国人提供将近 1/4 的能量 , 而且 , 和油不同 , 大部分天然气都产自美国 . 价格上涨时 , 生产者大力投资于新气源的勘探 . 但是现在价格大幅下降 , 因为经济大萧条减少了能量的需求 . 所以能源专家埃里克 . 波特说 , 现在想知道天然气页岩如何影响市场 , 还为时尚早 .

Drilling beneath the Bakken shale

formation in North Dakota

Russia is first in what are called "proved reserves" of natural gas. The United States is sixth. Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America. They drilled straight down into formations where gas collects. As these supplies were used up, big drillers looked for similar formations in other countries.

俄罗斯是已探明储量天然气最多的国家。美国列第六位。近些年来,美国大的石油和气体公司恢复方便开采的天然气的供应。他们直接向天然气聚集的岩石层钻井。当(该矿井内)气量用尽时,开采商便到其他地区寻找相似的岩土层。

But now the industry is taking a new look. Companies are developing gas supplies trapped in shale rock two to three thousand meters underground. They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock.

目前,该产业有了新的面貌。开采公司对地下2到3千米下的页岩石进行天然气开採。当钻到页岩时,从侧面将高压水、沙子和其它东西注入页岩内。

This causes the rock to break, or fracture, releasing the gas. Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states。

这会使页岩破碎而释放出气体。在阿巴拉奇亚山地区、密西根州和中南部几个州被认为有丰富的气页岩存在。

Gas shale exploration is being done mainly by small to medium sized companies.

气页岩开采目前主要由小型和中型公司进行。

Eric Potter is a program director in the Bureau of Economic Geology at the University of Texas at Austin.

Eric Potter是位于Austin特克萨斯大学经济地质学系的一个项目负责人。

ERIC POTTER: "The types of opportunities that are left for natural gas exploration in the U.S. have changed. So it's a different class of resource -- not as easy to develop, and not even recognized as something worth pursuing, say, twenty years ago."

Eric Potter:“这种被留下来的开采天然气的方式已经改变了。因为它是一种不同类的资源——不容易发展,也不容易被认识到有经营的价值,二十年前是这样”

He says more than half the gas in the United States is now coming from these new reserves.

他说美国超过一半的天然气来自新探明的储量。

But hydraulic fracturing can also produce debate and anger over the risk of groundwater pollution. This method of drilling is not federally supervised under the Safe Drinking Water Act. Some in Congress want to end that exemption from the law.

高压水沙破裂法会引发破坏地下水的争论和抱怨。根据安全饮用水法案,这种开采方法是不受联邦监管的。一些国会议员希望结束这种不受法律监管的状况。

Natural gas provides Americans with about one-fourth of their energy. And, unlike oil, most of it is produced in America. Gas producers invested heavily in reaching new supplies when prices were high. But prices are down sharply now because the recession cut demand for energy. So energy expert Eric Potter says it is too early to know how the new gas shale reserves will affect the market.

天然气供应占美国人能源消耗量的四分之一。不同于石油,其大部分是在美国生产。当价格上升时,天然气厂商提高产能。目前价格的下降是因为经济衰退引起的能源需求降低。因此,能源专家Eric Potter说这就很容易理解新的气页岩储量是如何影响市场的。

In the US, the New Look of Gas Exploration

美国天然气开发新貌

Transcript of Radio: 22 October 2009

This is the VOA Special English Economics Report.

这是美国之音特别英语的经济报道。

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water. But it also leads to a fossil fuel. Natural gas is considered the cleanest of the fossil fuels, the fuels created by plant and animal remains over millions of years.

很多人认为寻找清洁能源主要是像太阳能、风能、水能这样的可再生能源。但它同样也可是化石燃料。天然气被认为是最清洁的化石燃料,它是由植物和动物尸体经过数百万年转化而来的。

Burning it releases fewer pollutants than oil or coal. The gas is mainly methane. It produces half the carbon dioxide of other fossil fuels. So it may help cut the production of carbon gases linked to climate change. 

天然气点燃后释放出的污染物比石油或煤炭少的多。它的主要成分是甲烷。它产生的二氧化碳是其他化石燃料的一半。因此在气候变化上,它可帮助减少碳化气体的排放量。
