The commissioner of natural resources may adopt rules under chapter 14 relating to:

1. (1) spacing of oil and gas wells to regulate the density of drilling to prevent unnecessary draining of the reservoir and to prevent economic waste of products from wells;
2. (2) pooling, which is the combining of tracts and mineral interests to form a drilling or spacing unit; and
3. (3) unitization, which is the acquisition of the legal right to operate a whole reservoir as though all tracts overlying the reservoir were under a single lease.
