Rosemary,
I'm not sure I can answer your question. I would call Mr. Caldwell and if he can't help you possibly he knows of an oil/gas attorney he would recommend in the OK City area. Use this link for his phone #: http://www.beclaw.com/
Also you might want to call Gary L. Hutchinson-Minerals Management.
