Notwithstanding any other provisions of this chapter, where a parcel of land contains one acre or more and where all or substantially all of the surface of such parcel of land is unavailable for the surface location of oil or gas wells, there may be drilled or produced not more than one well into each acre of such parcel of land, and the surface location of such well may be located upon property which may or may not contain one acre or more of surface area, and the property upon the surface of which the surface location of such well may be located may or may not be contiguous to such parcel of land; provided: 1.

No operator shall construct or maintain any derrick within feet of any other derrick, then standing, of such operator unless approved in advance by the supervisor who may, in granting such approval, attach such conditions as are reasonably necessary to carry out the purposes of this chapter. 2.

The surface location of such well, as measured from the center of the hole, shall be not less than feet from an outer boundary of the surface of the property upon which such well is located, and shall be not less than feet from any dedicated public street, road or highway which is so dedicated and in such public use at the time of the commencement of drilling of such well. 3.

The producing interval of such well shall be not less than feet from an outer boundary of the parcel of land into which such producing interval is drilled, and the producing interval of such well shall be not less than feet, as measured horizontally in the same zone, from the producing interval of any other well which is producing or capable of producing oil or gas. If the parcel of land qualified to be drilled under this

section is less than feet in width, the producing interval of such well shall be as far from the lateral boundary lines of the property as is practicable. To enforce the provisions of this section, the supervisor may require, at the time supervisor gives approval of notice of intention to drill, redrill or deepen, that a subsurface directional survey be made for such well, and that a plat of said directional survey be filed with the supervisor within fifteen (15) days of completion.
