Breitburn bankruptcy

I live in North Dakota, have mineral rights in Martin and Howard counties operated by Breitburn, which is in federal bankruptcy proceedings. I have received 2 notices and continue to receive royalty payments. When I received the first bankruptcy notices I looked for information online and learned that in Texas courts, royalty owners generally have considerable protection when lessees are in bankruptcy, but I don't know how, or if, those precedents apply to federal proceedings. The first notice said a later notice would instruct me about stating any claims, which I would have no clue how to do, and so far can only assume that the process will generally work itself out, but if anyone has suggestions or advice I would appreciate it. I currently receive roughly $1500/year from this production, so my ownership is quite small.
