I understand you want what is owed to you. As you alluded to above, the Division Order analyst at Trinity assured you she is getting the pay decks together for the Dora #4 and Dora #5. You will eventually get paid. State law says so.
As to the Dora #2 and Dora #3, it is important to keep in mind context. Your minerals are in an area that produces natural gas. Natural gas prices have been collapsing as we currently have a glut in the United States and very little export capacity to sell it anywhere else. As a mineral owner, it is your right (or your predecessor in title’s right) to lease minerals for development. Trinity has developed your minerals and your lease is now held-by-production until all of the wells on your property stop producing. The ball is in Trinity’s court as to how fast they get around to drilling the Dora #2 and Dora #3. As to foot-dragging, if these were my minerals I would prefer Trinity not drill those remaining two locations until prices recover.
If you have offers to purchase your minerals outright that you deem lucrative, then by all means sell them. If you don’t need the money, it might be worth waiting. You have 2 wells about to start paying you monthly checks, and 2 more apparently in-process. All that is required now is patience.
