Glad to hear you were able to get some positive results. This will help you in your negotiation with the Bison landman. Have your negotiations been with Bison personnel or a lease broker? Keep copies of the OGLs you were able to uncover. They will help you get to the next negotiation stage by saying Bison has already made the accommodation in the area. That will be a persuasive argument at the COGCC pooling. A good result for a small fractional mineral owner is when they can have an OGL on equal terms to larger mineral owners.
Most professional mineral owners will attempt to negotiate the highest royalty possible when you are talking about lower bonus offers such as you have in Weld. I do not have any properties in this area, but a 10,000’+ horizontal well can easily come in at a cost of $10 million. At six wells per unit that would be $60 million for drilling and completion. At $1000/ac for 1280 acres that will yield a OGL bonus cost of $1.28 million. Most of these wells will produce 50% of their reserves in less than 3 years with the balance over the next 12-15 years. Given all this, the economics for OGLs is fought much more in the royalty area than bonus. If Bison drills the wells, then the higher royalty is generally the better option. If they do not drill, then obviously the higher bonus is best. You should not be surprised if they cool the development a bit due to the current oil and gas prices.
