This is my book that I mostly use as my reference on the blog, drillingformulas.com and I still use it for my every job on the rig. This book is very useful for drilling and workover people, and I can say that this is the “must have” book on drilling rigs or workover sites.
There are several pros of this book as listed below.
There are a lot of useful formulas required on drilling rig as pressure gradient, specific gravity, pump output, annular velocity, hydraulic, buoyancy factor, drilling fluids, cementing, well control, stuck pipe, etc.
All formulas are clearly explained and easy to follow for everyone. Moreover, an author, Norton J. Lapeyrouse, explains everything in the book with simple language.
There are a lot of examples showing you how to use formulas correctly; therefore, you will be able to apply formulas for your job correctly.
Size of the book is quite small so you can carry it with you and sometimes bring it to the rig floor. With this book, you don’t carry a briefcase of books to the rig floor and waste your time in order to find the right solution.
There are a lot of essential oil field conversion factors which help me a lot when I try to convert a metric unit into an oilfield unit, and vice versa.
There is also section about well control consisting several well control methods as a driller’s method, wait & weight, lubricate & bleed, stripping, etc. Many times in my oilfield career, I open this book as a reference when I perform well control operation.
Not only are basic formulas added in the book, but also there are some essential engineering formulas as bit nozzle selections, hydraulic analysis, fracture gradient, cutting slip velocity, surge and swab pressure, directional drilling, etc. These formulas are also simply described, and you are able to follow step-by-step. The book is not like some big engineering books showing you how to derive formulas.
Nowadays, there are two forms of this book which are a paper copy and an electronic copy (kindle book) that you can buy. Personally, I prefer the paper copy because I can easily carry it to the rig floor. I don’t like to bring a computer, a tablet or a kindle e-book reader with me on the rig floor because it is not convenience for me.
Conclusion: This book is dedicated to oilfield personnel worldwide who have to use drilling formulas for their jobs. This book helps me many times while I am working on the rig, and I think it will help you out too.
