(a) In every case where the area in which oil, gas, sulphur, or other minerals sold is contiguous or adjacent to lands which are not lands belonging to and held by the university, the acceptance of the bid and the sale made thereby shall constitute an obligation of the lessee to adequately protect the land leased from drainage from the adjacent lands to the extent that a reasonably prudent operator would do under the same and similar circumstances.
(b) In cases where the area in which the oil, gas, sulphur, or other minerals sold is contiguous to other lands belonging to and held by the university which have been leased or sold at a lesser royalty, the lessee shall protect the land from drainage from the lands leased or sold for a lesser royalty.
(c) On failure to protect the land from drainage as provided in this section, the sale and all rights acquired may be forfeited by the board in the manner provided in Section 109.167 for forfeitures.
