If you are a Drilling Supervisor or a Well Site Drilling Engineer, you have, no doubt, made several spreadsheets over the years to calculate various tasks, such as casing cement jobs, hydraulics, balanced cement plugs, liner cementation, etc, etc.

And then suddenly, your company changes Cementing Contractor, and here you are, you can start all over, because none of the chemicals in the new recipes have the same units as your program has, rendering your formulas for mix-water calculations useless.

Or, you change rig, and now you find yourself using 4" DP, running 10-3/8" casing, drilling 8-3/4" hole using Duplex mud pumps, instead of the good ol' 5" DP, 9-5/8" casing, 8-1/2" hole and triplex pumps, which all your spreadsheets formulas are based on. Oh shit! What do you do then? Call the Mud Loggers?

Consequently, I decided to make a program which would make ALL my calculations REGARDLESS OF which rig I was on, and who was the cementing contractor, etc, etc. And... "Sargent's Drilling Utilities" is it.
