1. (a) Acreage up to the amount specified in applicable field rules may be pooled into a development or proration unit, provided that an operator must file with the commission a certified plat delineating the pooled unit, and a certificate of pooling authority wherein it is stated that the tracts are pooled by authority of an agreement between the various interest holders in the several tracts committed to the unit, with such tracts separately identified and the gross number of acres in each of said tracts shown separately, with a total gross acreage allowed not to exceed the unit size authorized by rule.
2. (b) If a tract to be pooled has an outstanding interest for which pooling authority does not exist, the tract may be assigned to a unit where authority exists in the remaining undivided interest, provided, that total gross acreage in the tract is included for allocation purposes, and the certificate filed with the commission shows that a certain undivided interest is outstanding in the tract. The commission will not allow an operator to assign only his undivided interest out of a basic tract, where a nonpooled interest exists.
3. (c) The nonpooled undivided interest holder retains his development rights in his basic tract, and should such rights be exercised, authority to develop the basic tract be approved by the commission, and a well completed as a producer thereon, then the entire interest in the basic tract must be allocated to said well, and any interest insofar as it is pooled with another tract must be assigned to the well on the basic tract for allocation purposes. Splitting of undivided interest in a basic tract between two or more wells on two or more tracts is not acceptable.
4. (d) Acreage assigned to a well for drilling and development, or for allocation of allowable, shall not be assigned to any other well or wells projected to or completed in the same reservoir; such duplicate assignment of acreage is not acceptable, provided, however, that this limitation shall not prevent the reformation of development or proration units so long as no duplicate assignment of acreage occurs, and further, that such reformation does not violate other conservation regulations.
