Garbage
Most of the formulas don’t work, kind of disappointed as it would be a handy app for displacements or spotting lcm but like I said, formulas don’t work on my phone.
Please update
Needs to be updated. Not enough casing sizes.
Save your money
Inaccurate and difficult to use. Don't try and contact developer from app, my second wife is more helpful and responsive.
Weight
Should add KG/M3 for fluid weights.
Waste of money
I want my money back. Payed $12 for this app and the displacement calculations aren't even right. Says 5 1/2 23 ppf casing bbls/ft is 0.00820. Way off. C'mon man
Soooo not worth it
It's fun to play with while watching the guys pull pipe or when logging but not allot of things I can use on a day to day basis. My free well control data book and a calculator are WAY more useful
Essential
Not worth it. App does simple calculations that can be done on calculator and has no value tables.
wrong!!
the bottoms up calculations are completely WRONG!!!!
