刚好看到这里,说说我的理解。
1.目前对于页岩气/页岩油的环境影响争论比较大,主要集中在以下3个:
a.压裂中使用化学添加剂,包括聚合物,表面活性剂,灭菌等是否会泄露并影响地下
水饮用水源。另外,在页岩气生产中大量的用水(75-85%)会反排,水中包含大量化学物
质,如何进行水处理和用水优化也是当前的大问题。
** 一般来说地下饮用水源在1000ft的深度不到,而页岩气压裂大部分是在6000ft深
度,不少在10,000ft以上,所以对于地下水源污染大众目前有误解。
** 另外,水处理在页岩气中也是非常大的一项,按照单口井1万方的用水压裂,反
排也是进1万方水要处理,一个区块上百口井那么就是上百万方的水要处理,这个对于
环境工程也是非常大的一块。目前页岩气田现场的水处理方法是传统的过滤-》絮凝-
》沉淀。如果有清楚油气田水处理的同学可以详细展开说说。
b.在页岩气生产过程中天然气是否会泄露到大气或者地表水/地下水中
** 如果钻井完井没有做好,确实会有泄露,不过这个跟页岩气关系并不大,主要是
工程质量问题。
c.在水利压裂过程中是否会引发地震
** 如果压裂打到断... 阅读全帖

另外,在石油领域而言,水力压裂已经很早就在运用了,刚开始是在传统的油气田做酸
化或者压裂,而且非常的普遍的。在页岩气领域压裂大范围推广应该是在90年代中开始
了,特别是到2000年初的时候普及。
按照能源展望Annual energy outlook的评估,天然气/页岩气做为清洁能源,在2015年
到2020年将占到化石能源发电的35%左右,超过煤炭和石油。其前景非常可观。由于页
岩气的近10年的发展使得美国气价一直不断走低,由天然气进口国慢慢转变成出口国。
所以美国根据页岩气发展提出页岩油将会改变世界格局。
如果大家注意国内形势也许会知道,国内政府大力推动页岩气,有想创业的或者找机遇
的,这将是下个发展的黄金时期。

标 题: 2015 April PE考试归来
发信站: BBS 未名空间站 (Mon Apr 20 11:53:02 2015, 美东)
一直关注别人写的关于PE考试的帖子,终于轮到我也来写点东西了,希望对后面的人有
用。如何报名就不讨论了,是个非常麻烦的事情,我去年十月份还因为忘记到national
board去注册而失去考试机会。有人说,PE考试报名比考试难,我看也不夸张。
我的背景:本科是hydrogeology,master是环境工程,phd是土木与环境工程系。名字
是不同,但是学的东西基本都是groundwater modeling方面的,所以都不敢说自己是
Civil Engineer。
报考科目: Civil – Water Resources and Environmental。 选择这个科目是因为对
环境也不懂,对土木也不懂,所以考环境工程未必有优势,加上我们的同事也考了这个
科目,于是我也选择了这个。

大家好,我是环境海归一周年的作者,借着现在韩国,在发一篇吧。原来不知道mitbbs
上还有我们环境人专门的板块,也感谢论坛里朋友的提醒,并把我的文章转载到了环境
版。感觉大家对我的信任,并且和我邮件联系,讨论关于国内环保的趋势,选了两个关
键性问题回答一下,希望对想回国的朋友有所帮助。
1.国内学术界就职
我在文中说到了的我的母校要招聘我回去当老师的事情。其实我的母校不是国内一类院
校,是辽宁的一所二本院校,排名在辽宁的高校里也就5到10名之间吧,不是大连理工
那个等次的。而且我回国也没联系过高校,只是一直跟母校的几个老师一直有联系,回
国的时候拜访了他们一下。几个朋友简单说了他们的情况,让我评估一下他们如果回学
校的话,能做到什么位置。
给大家两个参考吧(绝对真实的),考虑到他人的个人隐私,就不说姓名和去的学校了。
(1)在日本做博后大概3到4年吧,生物工程方向,发表很多高水平文章,很多都发表
在环境领域生物方面很不错的杂志,大概30-40篇左右,被中国一个很有名的学校聘为
正教授,给了“杰出青年专家”类似的头衔;

It is a very stupid question -_____-, but I still want to know how.
I have the DEM file, and now i just need a small piece of it. I have a
polygon(shapefile), which is the boundary of a watershed, and now I want to
cut the DEM file using this polygon. But Arc just does not allow me to do
that. I used the Analysis Tools--Extract--Clip. But I can not input the DEM
file...Why?
I am not a master of GIS, just need to use the DEM file to finish my
hydrologic analysis.....

老婆现在国内搞水资源的规划,数值模拟,工作也还出色,但是也没有什么发展前途,
还在北京某中科院研究所读part time 的phd(part time的水啊)。现在想F1过来(原
谅我这边钱少,非理工科)。重新在这边读PHD不现实,年纪大了;读master不知哪个
方向更好找工作。
1,申water resource方向的PHD,然后中途转硕,这样伤人品,但是能拿到钱啊。
2,申Master,方向:1)hydrology或environment engineering(水资源规划管理等)
,2),hydrogeology(劳工部网上说工作机会能增长26 percent,估计瞎扯)3),
GIS或者Remote sensing,主要是应用在环境如水,土等。
请问以上master方向哪个就业最好,老婆有国内五年相关经验,只要毕业能找个一般的
工作就行。
申Master需要有tutition waiver,自己掏学费是在有点吃不消。她gpa强,应该能拿到

来自主题: DataSciences版 - suggestion on geospatial data? (转载)
In GIS (geographic information science), spatial analysis to find best
location usually needs more than one data layer. For example, to find gold
mine in the mining industry, the GIS Specialist/scientist will consider the
geology data, hydrology data, soil data, vegetation data, elevation data (
slope, aspect, etc.), besides the existing location of gold mines.
