You can find the production at the OK tax site. It is also on your run tickets. It is a rollup for the whole field. The wells in your tract are just a small part of the whole. https://otcportal.tax.ok.gov/gpx/gp_displayPublicPUNListSearchDownload.php
You can find the unitization and how that changed your percentage. You are part of a large secondary recovery project so are now receiving your portion of the whole field’s production based upon your acreage in sec 4.

As the Mach activities progress, you will receive the relevant OCC paperwork. (if your name and address are properly filed in the Kingfisher courthouse).
Your lease did not change, but the decimal interest has been changed and overridden by the secondary recovery documents and rulings by the OCC regarding them. Secondary recovery units do charge post production charges, but the offsetting benefit is that instead of only getting paid on your wells on your tract, you now get paid on all of the wells in the field! If all the wells on your tract cease production, you still get paid on the rest of the remaining producing wells. Secondary recovery can extend field life for decades!
