Burke county activity

What new activity is there in Burke county? Who is actively exploring and leasing? I have 160 acres of mineral rights not leased in 163N 90W Section 6. We also have 640 acres leased in East Flaxton Madison unit. The operator was Cobra Oil but we haven’t received any checks the last few months. I am being told Cobra Oil sold the lease to Palo Alto. Anyone have contact info on them? I can’t find anything on ND site about them as the operator. Does this mean my original lease is void? Can I file a release or request one from Cobra? Thank you

6-163N-90W has an old dry hole in it. Last leases were in 2018.

What section, township and range for the East Flaxton Madison area? If production is low, you may not have enough royalties to meet your minimum check amounts. As long as there is production under the terms of your lease, you are still held by production.

Here is a screenshot from the NDIC site. Cobra is still listed. Looks like many of the wells are inactive or Plugged. GOFOROIL and EAGLE OPERATING were other operators. 23H has very low production at 14 bbls for July. 26H had 55 bbls for Sept. 22 5 bbls in July. The field is almost finished.
