There are a lot of people who are interested in well control and we would like to help them learn and make their life easier by sharing the well control spread sheet. The image (Figure 1) below is the screen shot of the spread sheet.

**Version 1.3 updated on 28-Jan-19.**

In this version (1.3), the spreadsheet is updated into .xlxs file which is the newest Excel Version. Moreover, all formulas are unlocked so you can modify to suit for you needs too.

Buenas noches, los saludo cordialmente.

Dentro de sus amabilidades, fuera usted tan amable de indicarnos el calculo hidráulico de las barrenas?, o cual seria según cálculos el flujo de lodo para que su efectividad de perforar sea el optimo?

Sldos,

Julio Herman Blanco García.

Good evening, I greet you cordially.

Within their kindnesses you kindly indicate the hydraulic calculation bits out?, Or calculations which would flow according to their effectiveness mud drilling is optimal?

Sldos,

Herman Garcia Blanco in July.

It is in our drillingformula spread sheet.

Excellent.Keep it up guys.this side is very good regarding formulas.Appriciated
