"按照手册里的Step by step,基本可以完成Petrel的自学"
That is incorrect, if you master the step by step without the modeling fundamental , you are at best a mouse clicking, buttons pushing monkey.
"Petrel2008与Petrel2002,在基本操作上没有区别"
Gee, you insulted all the hard working Petrel developers in one stroke. You also shows your poor understanding of the evolving modeling technology. Are you sure what Petrel is for? Anyway, you don't need to answer, you already answered my question with this statement "从来没人给我培训过。 ". As a mentor to many young professionals, I found those 从来没人给我培训过 are hard nuts to crack. They have their opinion (even it is 100% incorrect), and they are closed minded. Therefore it is not trainable.
Petrel is all about workflows, if you have solid understanding of modeling, eg, why we do model and what kind of model for certain project, what kind of data we needed and their uncertainty, then learning Petrel is easy. The step-by-step instructions will make sense and you don't waste a brain cell to memorize them.
So if you don't know what modeling is, I strongly advise you not to waste time reading a manual that you have no use. Use your resource wisely, learn GGRe fundamentals.
