要多产生多少利润才能弥补upstream利润的减少呢？
没留心过bp价格，不知道是不是合理。只是针对你提出的下游利润补上去，觉得不合理

得了两个Intern职位的offer，但因为是转行，所以对整个行业的把握并不是很充分。
所以如何取舍还希望大家给点意见！多谢多谢！
1. Shell downstream 做retail fuel的组，比如V power等等，和chemistry相关。在
Shell Global Solutions下面。虽然是downstream，但是和我PhD做的东西比较接近，
而且听说似乎更容易拿return offer。但是现在大环境下裁人不断，是否会停止招人？
还是边裁老人边招新人？油价下跌似乎downstream盈利空间还上涨了？
2. Exxon Mobil 的Upstream Research Company，做chemical corrosive相关的
project，和我PhD不是很相关，而且Exxon Mobil的return offer rate本身就很低，基
本拿return offer的可能性就很小很小了。但是Upstream毕竟是石油行业的核心部门，

How much does it cost to produce crude oil and natural gas?
A measure of the total cost to produce crude oil and natural gas is the
upstream costs. The upstream cost includes lifting and finding costs.
Lifting costs are the costs to operate and maintain oil and gas wells and
related equipment and facilities to bring oil and gas to the surface.
Finding costs are the costs of exploring for and developing reserves of oil

activates the proteins.[5][6][7][8] It was named furin because it was in
the upstream region of an oncogene known as FES. The gene was known as FUR (

发帖数: 1501 | 23 先看一下有没有其他的code， 如果没有，就只有P0420，这个code是说catalytic
converter不能有效的转化废气，车子是通过比较catalytic converter前面和后面的
oxygen sensor的信号来决定catalytic converter是不是有效，upstream的oxygen
sensor的信号应该是不断变化，上下摆动，downstream的要相对稳定，如果downstream
的信号和upstream的相比变化频率过高，车子就会认为catalytic converter不行了。
我觉得这个最有可能是catalytic converter的问题。也有可能是oxygen sensor的问题
，如果只是oxygen sensor的问题，那得是上游的oxygen损坏到信号转换频率比较低，
但是没有低到让车子显示oxygen sensor的code，或者是下游的oxygen sensor损坏使得
信号频率转换过快（oxygen sensor坏了一般不会增加switich的频率，所以这个得损坏
