OK, That makes sense. They are the operator of the Jewel 1003-2HX horizontal well. The well was drilled in 2018 and has been online since 2019. It is a horizontal gas well. The well has part of its length in section 3 but most of the length in section 10. You will not get a new lease agreement as the well is still in production. You just want a copy of the original lease. The decimal percentage that you get on the well is from an equation. Net acres/actual spacing acres x royalty x percentage of the well in your section. She likely had a low net acres and a low percentage of perforations in sec 3.
The 90 days does seem rather excessive, but you should get a bundled check with the back pay when they have completed their paperwork. The well is healthy and has many more years of life left to it unless something unusual happens.
You may be able to get a copy of the lease by looking on www.okcountyrecords.com. It is free to look. Use the advanced search option.
