Formulas and Calculations for Drilling, Production, and Workover: All the Formulas You Need to Solve Drilling and Production Problems 4th Edition

Easy to use and a large range of formulas very useful!

I always have with me offshore...

Excellent organization of material. A "MUST HAVE" book for all oil & gas workers.

Great book but it is a little more for Engineers, I was expecting it to be more for the man on the rig.

This is a drilling consultant / engineer book period. Don't waste your money like I did on a book that I thought would be helpful for workover/production.
