How is it determined that if I have an interest of 0.00204199 and my royalty was increased from 3/16 to 6/16. What would my new interest be?
The decimal is a combination of your net acres/actual spacing acres x royalty x % perforations in your section.
An example would be 7 net acres/640 spacing acres x .1875 x 1.0=0.00205078125. That is pretty close to what you have now. I assumed a horizontal one section well so 100% of the acres are in one section. Why do you think you have 6/16? That royalty would be very unusual. It could be that your net acres are different, the gross acres are different, the perfs percentage could be different. What document are you looking at?
