Hello!
I have a lease with Prima Exploration Inc, (originally signed 06-14-2012 by my late Mother with Plains Marketing) and am currently receiving royalties on the Amundsen Well. Township 160 North, Range 100 West, 5th PM Section 22: NWNE, E2NW, E2SW
Divide County, ND
I have received a letter inviting me to join a Communized Account with BLM for spacing reasons regarding the Smokey Butte-Bakken well.
The letter says I have 10 days to sign, and that if the signed documents are not received within 10 days, they will automatically add me to the CA.
Am I obligated to join the CA?
Am I giving up ownership of the mineral rights by doing so?
Is there any benefit of joining the CA?
I am just beginning to learn about these mineral interests that were left by my Mother. I have no idea what effect joining a CA will have.
Thank you for any insight you can offer!

If you Google โWhat does a communitized account with the BLM mean in North Dakota spacing?โ it gives a pretty good basic explanation. It is basically combining your acreage with federal acreage to create a larger spacing unit for drilling. You do not give up your mineral acreage. It probably gives a better chance for drilling and more royalties for you if the new well is productive.

Thank you for your reply!
So does the decimal interest change on the division order for the well that is already leased, or just any newly drilled wells?

The already drilled well will probably stay the same, but the new ones will have a different spacing and lateral length, so will be different.
