70/350 = .2000
2.333/5 (20%) = .04 x total of production
Production is based on the amount of oil or gas and the dollar amount on what it was sold for times the production.
That only gives you an approximate amount, as you can’t always pin down what it was sold for, etc. Gives only an idea. Once you know your division factor you can get closer.
We just went through that whole process. It has been a blessing for all of us. God bless.
