I have run across several instances of a lessee releasing a lease for minerals in a producing unit.  I am interested in how often this is happening and if anyone may have received a notice or an explanation why this has happened.  For those members who may not be comfortable with posting in an open discussion thread, please post on my private page.  Just click on my name in blue.  My page is set to private so if you are not already my "friend", send me a request.
