If they are calling NGL's "oil" then that sounds about right. OIl and NGL's are priced separately based on supply/demand at that current sales location. Take a look at your dry gas price....I bet it is very very low.
Marcellus NGL do not have a hub price. Word on the street is that NGL in the Marcellus go for 60-70% maybe up to 80% of the current WTI crude oil price. 60% of $50.00 is $30.00.
What was the royalty for oil before?
Oil prices haven't changed that much recently. They dipped below $50 for a little while at the beginning of the year but have stayed between $50 and $60 the rest of the year.
