来自主题: Texas版 - Petrophysicist vs Petroleum engineer
个人理解:
公司最牛的应该是geologist,编故事忽悠找油的那群人。找到了油就是大功劳啊!
Petrophysicist 就是搞岩石物理的,给真正做地震波成像的数学大拿们(geophysicist
)提供数据给他们建model....
Reservoir engineer 是搞油田开采模拟的。油田开采乱搞的话一个油田可能没采几年
就大部分产的都是水了。要最大限度的实现快(单位时间产的多)和多(总的recovery
要optimize)
偶不属于以上任何一种,如果有出入专家请不要扔砖头。。。

google一下。感觉学费投入和工资产出比来说,职业排名如下:
Petrophysicist 》petroleum》geophysicist》geologist。
前2者硕士较多,后面的PhD比较多。

我是今年4月1号申请的H1B,我实际的job title 是Geologist, 但可能因为实际工资没
有达到标准,公司的律师用另一个title ‘GIS' 帮我伸的H1B (抽签抽到了)。 H1B
申请资料里的job description也都是关于‘GIS'的,和我实际的工作内容有出入。
1:我今年11月份要回国,在填DS-160表的时侯, 'Briefly describe your job
duties' 那一项是应该填我的实际工作description吗?还是应该按照H1B申请资料填成
‘GIS’?
2:回国面签的时候签证官如果问我的工作是什么我应该怎么说呢?
(如果你们有人认识我的话,这个不是我自己哈,帮没有mitbbs帐号的人问的。)

1) 凡是大于2:1的土坡,在水的存在的情况下,都有失稳的可能。局部滑坡和整体滑
坡都会出现。
2) 如果contractor真是说“geologist"而不是“geotechnical engineer",趁早找别
人评估好了。
3) 其实,应该首先联系一个geotechnical consulting company, 等分析完了,再找
contractor来施工。一般来说contractor自说自话,评估设计会有conflict of
interest.
4) 还有就是要看看附近的right of way,到底土坡顶和底部到底位于r
ight of way的什么部位。这对financial liability
的区分很重要。
5)可以考虑挖导水沟来利用重力减小土坡上部的重量。
以上不构成任何专业建议。
