Pooling is a type of forced leasing that happens when an operator is ready to drill and the leasing is not 100% done. It is overseen by the Oklahoma Corporation Commission. It will be limited to a certain number of reservoir zones and have a time limit of 180 days or 365 days (unless extended). You will have several choices of bonus/royalty pairs. The terms of the pooling are your “lease”. The OCC will hear the operators case and then set those terms. You will have 20 calendar days in which to answer or they will pick the lowest royalty option for you and hold the funds in suspense. Then drilling can move forward.
You can lease with their leasing agent or any other agent up until that 20 days ends, but I don’t like to wait until the last minute. If you are new to this whole thing, I would encourage you to read the Mineral Help Tab above and read over all of the Grady discussions for the last few months. You need to get familiar with what lease clauses are good for you and what are not and need negotiation. Come back and ask lots of questions. Most of us that have been mineral owners for a while would probably not sign the first lease that was put in front of us or accept the money offer either. Important to get the best deal that you can because it may hold your family for decades.
