Drilling Data Handbook 9th Edition

All Arrived well, as expected.

Perfect

Excellent book! Quick access to basic information. More updates compare with previous version. Good quality print. Very helpfull in my daily work.

Is a awesome book

Thought it was a "Directional Drilling Handbook" Listing on line was and still is confusing. For what it is, it seems fine.

Expensive but well worth it.

I call it the oil feild bible
