Eog morris wells

I have intrest in morris a and morris b wells in Montague county. Production was steady until Nov. and Dec of 2013 when it seems all production may have ceased. Calls to EOG investor relations have not been answered. These wells have been producing a little over two years at a pretty steady rate. On the RR comission site production for one was zero in Nov. and Dec productions are not reported but it is reflected as zero in recent royalty check. What is happening here??? What are the logical explainations and where do you go for verification of possible answers?
