Drilling formula spread update will be distributed on 18-May-11

I just have time and I will add some drilling formulas in the drilling formulas spread sheet. It will be version 1.1.

I will distribute this sheet on 18-May-11.

The drilling formula is still FREE and I wish this sheet would help you understand more about drilling and use it for your work.
