Formulas and Calculations

Formulas and associated calculations are important for design, drilling engineering and drilling operations. Few equations and related calculations are given in the following pages.

The intent is to provide basic equations and formulas for downhole drilling operations. The readers may find it as a tutorial guide. It is known that it will be very difficult to cover all the aspects and areas of drilling and it is hoped that the page will be updated with additional topics.
