Leases in 8N3W of McClain County, Ok

We own 100% of oil & gas in Section 17 Township 8N, 3W of McClain County. We have been approached to lease entire section and have no idea what is a good lease or what to be aware of before we sign. Also, we have been offered $200 per acre in Section 18 verbally. We were offered 1/5 in Section 17 and have received the written lease. Is that a good offer? Should we have an oil and gas attorney in Norman look at the leases and would he know what is a good offer? Who is best oil & gas attorney in Norman? Thank you.

If you are unfamiliar, have an attorney examine the lease. Make sure you attach an exhibit with depth, Pugh etc. clauses.
