中国石化新闻网讯 据路透社12月11日里斯本报道,澳大利亚石油天然气公司(Australis Oil & gas)的老板表示,在葡萄牙境内卢西塔尼亚盆地(Lusitanian basin)勘探碳氢化合物,可能会发现足够供应整个国家两年半的天然气。该公司拥有该地区两个特许权。
“葡萄牙的开发率相对较低,但成功率相对较高,”首席执行官Ian Lusted告诉路透社。“但迄今为止,没有相当大的发现,该国根本没有碳氢化合物生产。”
该公司在2015年获得了为期8年的勘探许可证。据该公司表示,迄今为止,该国共钻探了148口陆上油井,其中多数为不足500米的浅井。
然而,从该公司在葡萄牙中部Batalha和Pombal已钻探的油井来看-这两处油田为该公司所有,有迹象表明两套油气系统仍在工作。
“我们有独立的工程师,他们评估了整个葡萄牙的可采储量约为两年半,”Lusted说。2017年,葡萄牙的天然气消费量估计为61.5亿立方米(2172亿立方英尺)。
“这对该国可能非常有利,并且与政府政策紧密相关,”Lusted补充道。
政府在12月初表示,其目标是到2030年可再生能源占葡萄牙能源的80%,到2050年将达到100%。
环保主义者对天然气项目表示担忧,尽管它是一种比石油更清洁的能源,并且随着该国转向可再生能源,可以在过渡时期使用。
这两个地区的钻探工作可能会在2020年初开始,但仍需要由环保部门进行评估。
环保主义者还担心这家澳大利亚公司可能会使用一种称为水力压裂的提取工艺,这种方法在一些国家被批评为扰乱当地社区。Lusted否认了这一说法,称该公司只会被允许“钻井并按常规生产”。
当地非政府组织ASMAA在5000多人签署的请愿书中写道,“澳大利亚人将钻探的特许权包括人口密度高的地区,许多具有文化和历史意义的地区,以及许多自然保护区”。

Australian company targets 'under-explored' gas in Portugal
A search for hydrocarbons in Portugal’s onshore Lusitanian basin could reveal enough natural gas to supply the whole country for two-and-a-half years, according to the boss of Australis Oil & Gas, which has exclusive rights to two concessions in the area.
“Portugal is relatively under-explored but there is a relatively high success rate,” Chief Executive Ian Lusted told Reuters. “But to date there have been no sizeable findings and there is no hydrocarbon production at all in the country.”
According to the company, which won an eight-year- exploration licence in 2015, a total of 148 onshore wells have been drilled in the country so far, with the majority being shallow wells of less than 500 metres.
However, from the wells already drilled in Batalha and Pombal in central Portugal - the two concessions owned by the company - there are indications of two working hydrocarbon systems.
“We had independent engineers who assessed that the recoverable volume was about two-and-a-half years of supply for the whole of Portugal,” Lusted said. Portugal’s natural gas consumption was estimated at 6.15 billion cubic meters (217.2 billion cu ft) in 2017.
“This is potentially very beneficial for the country and it ties up with government policy,” Lusted added.
The government said early in December it was aiming for renewable energy sources to account for 80 percent of Portugal’s energy by 2030, rising to 100 percent in 2050.
Environmentalists have expressed concerns about the natural gas project, even though it is a cleaner energy source than oil and could be used in a transition period as the country turns to renewables.
The drilling in the two areas could start in early 2020 but it still has to be assessed by environmental authorities.
Environmentalists also fear the Australian company could use an extraction process known as fracking, which has been criticised in some countries for disrupting local communities. Lusted denied this, saying the company would only be allowed to “drill a well and produce it conventionally”.
In a petition signed by more than 5,000 people, local non-governmental organisation ASMAA wrote that “the concessions where Australis will drill include areas of high population density, and many areas of cultural and historical interest, as well as many nature reserves”.
