Normal...but do not sign it. Demand "NO POST-PRODUCTION" EXPENSE... none, nada, never. I would give up some reasonable part of the check royalty first. If they can take any percent then 3/16th ends up being 1/8th or less
I just calculated several similar leases and the post-production expenses were from 21% to 32%... ONE - THIRD.
As wells decrease in volume and pressure, the compressor charges eat you alive. The "marketing" expense...OK, what's that????
Further, I would DEMAND some sort of price transparency.
Also make sure that the lease only covers one property in one drilling unit. The rest are not to be "Held by Production"
