Coming from a petroleum engineering POV, there is nothing special or super interesting about this book. The stats are recent enough, but the industry just moves so fast that they seem out of date with what I read on a daily basis. Sill, good for a beginner or someone looking to get more than a 'for idiots' summary of shale operations.
I did not give it full stars because it looks like the editor or publisher thought they could get by with copy and pasting the same thing about 3 or 4 times over. The introduction had the same sentences as the govt. report that directly followed it, which was then followed by comments from the authors or something that were also exactly the same. And the copy-pasted sentences weren't even very good grammatically. It sounded like someone rambled onto paper and then copied it down adding punctuation and random points. After the multiple intros were over though, it became informative and covered a lot, including the span of the formations and the legal atmosphere side of things. Not exactly what I was looking for (technical material on shale operations, but not quite technical papers), more of an unbiased introduction.
