Help with missing NGL payments Logan County

I am a mineral owner in the NW Lawrie Oswego Unit in Logan County , OK. The unit is operated by OSO Resources. For 2 years we have attempted to get our NGL payments - OCC does not handle royalty issues - Attorney Generals office forwarded them a complaint in January and still nothing. Oil and gas attorneys protect the oil companies - (we have contacted several) I joined NARO in anticipation that they would have resources for mineral owners regarding this- or attorneys that represented mineral owners but they do not. Is the best option to find an out of state attorney, file a breach of contract??? File a lien? So so frustrated. Anyone have suggestions?

Have you used the preferred vendors list from NARO (part of your membership perks)?

What is the section, township and range so I can look up the unit to see if there is any NGLs to be tracked down.
