Ratings and Reviews


Just equations

This is just a page of equations. Not very helpful to a mud engineer. Needs to have fields for entries, so equations could be calculated automatically.

Very good


This is a good little application for using in the oil industry, but not only there. It has some basic information and it has some professional one. I have to say it was useful for me at school, for example.

Nice hand calculations


The app got high quality graphics, illustrations are colorful and clear definitions as well as the most accurate hand calculations supports engineers, specialist who are involved in Oil and Gas exploration. The actions redirect streamlined and easy to understand.
