I have not received payment yet, but am I being paid on current prices after they sell the oil/gas or on the price at time it is put "in the barrel"?
Not exactly following your question but if you are referring to whether or not you are paying transportation charges on the oil, read your lease as this is where your answer will be found.
Royalty is based on sales, you royalty is calculated from how much they received when they sold it, not it's value when it was produced.
I am in Texas so I figure about $100.00 per barrel, minus 15 to 16% expenses, minus county tax. That is what you will receive. Then you have to deal with the taxman yourself. I put about 30% away for that.
