Jackson county mineral interests

I own several deeds in T9N-R78W in Jackson county but have not received royalties on gas production there for quite some time. This used to be a good source of income for me; the wells did not seem to be declining significantly in output, but then the checks just suddenly stopped coming. I tried to contact the operators at the time to ask what happened, but never received replies. The specific leases were named Blevins A & Blevins B, and were located in Sections 3, 10 and 11. Just wondering if there's still production going on there, and if so, who the current operators are. Thanks in advance for any help or suggestions that members here might be able to offer. -Scott Shannon
