Communitization (Pooling)

Provides for the pooling of federal and/or Indian lands, with other lands, when separate tracts under such federal and Indian lands cannot be independently developed and operated in conformity with an established well-spacing program.


  • In order to streamline the approval process, it is no longer required to provide Federal lessee or Federal operating rights owners signatures with the submitted CA as long as there is an approved spacing and forced pooling order from the North Dakota Industrial Commission (NDIC).  Only the CA operator's signature is required.
  • For Federal CAs you do not have to include the Pooling Clause in Exhibit B if you have a State forced pooling order. If you do not have a State forced pooling order in place, then you must include the Pooling Clause for each lease in Exhibit B with the exact wording of the independent pooling agreement.
  • It is no longer required to provide the ORIGINAL LESSEE or the ORRI NAME AND PERCENT OF INTEREST in the Exhibit B for either Federal CAs or Indian CAs.
