thanks for your efforts

How can i get metric versions of the calculations & formulas?

I don’t have the metric version right now. You may need to use the conversion program to help you.

Hi,

Would it be good the drilling formula above in spreadsheet using both imperical and metrix unit?. Or have an option that allow user to change the units?

Thanks,

Luis

There is only oilfield unit at the moment.

I downloaded the sheet but I think there are some pages where the input cells are not active, means I can not enter the values like the Reynolds number page, and may be there are others.

You need to download the lasted one, version 1.5.

Hellow there

i wonder wheather you have an idea on how to creat a spread sheet for hydraulics optimisation

using the two critera max HSI and Max FI

thankx in advance

I don’t have an idea to create this spreadsheet. I am sorry about this.

very good tool
