NE4,Sec 28, Block 37, T5N,T&P RR CO. Lease offer $450 per per acre royalty 22.50%???
Is there a block 37 in Dawson county?
No I don’t believe so. Assume its 34, 35, or 36 T5 but 
Ask for the bells and whistles on the addendum, 25% bonus. Your bonus consideration doesn’t mean as much
as others have shared, there is no Block 37 for sec 28 in T5N T&P RR CO survey. your options are Block 33, 34, 35, or 36. If you can clarify - someone might be able to assist.
that said, I’d typically focus on the royalty more than the bonus. having said that, I believe 25% is probably more standard, so 22.5% sounds a bit low to me.
welcome to the community Jen27!
Sorry it is 36. Bonus $450 royalty 22.50%. Decent offer? 13 acres
hello @Jen27
thanks for updating the block. I took a look on RRC. not a lot going on in that area - but for transparency - I’m not familiar with this area. as I said earlier - I believe 25% is probably more standard. I’ve attached a pic of the area for you.
one more observation - I don’t see any permitted wells in that NE section.
If you want to do a bit of market value research, the you can use TexasFile.com to check out recent OGL activity. Many companies today file OGL Memos which will not prove helpful; however, you can contact the lessors and ask for the terms of their OGL (hint: look to contact only the pros). As far as OGL addendums, that is a complex negotiation. To be effective, terms need to carefully crafted that in most cases require some level of professional involvement. Good luck.
