2.      That the Commission has jurisdiction over the subject matter embraced in said notice and of the parties interested therein, and jurisdiction to promulgate the hereinafter prescribed order.

Section 27:  S/2	Section 33:  All
Section 28:  S/2	Section 34:  All

and is referred to as the Buckingham Field.

4.      That in order to prevent waste of oil and gas as defined in the Colorado Oil and Gas Conservation Act of 1951, as amended, and to prevent the drilling of unnecessary wells, an order should be made establishing forty (40) acre drilling and spacing units for the production of oil and gas from the "D" sand, common source of supply underlying the Buckingham Field described above; that said units should be forty (40) acre drilling and spacing units according to the governmental survey thereof; that the permitted well for each drilling unit should be located in the center of each quarter-quarter section in the governmental survey; and that a tolerance of One Hundred (100) feet in any direction from the prescribed location should be permitted to avoid surface hazards and obstructions.

5.      That all available geological and engineering data concerning the "D" sand, common source of supply in said Buckingham Field indicate that one well will efficiently and economically drain an area of approximately forty (40) acres, and that drilling units of the size and shape hereinabove described are not smaller than the maximum area that can be efficiently drained by one well producing from the said "D" sand, common source of supply in said Buckingham Field.

6.      That exceptions should be allowed for the following wells and that each of said wells should be the permitted oil or gas well for the drilling and spac-ing unit upon which it is located:

Shell Oil Company #1 Huldah A. Hanson

IT IS FURTHER ORDERED, that by order of the Commission, after due notice and hearing, said Buckingham Field, "D" sand, common source of supply, may be redesignated from time to time to embrace other lands in the vicinity which are believed on the basis of additional development to be capable of producing oil and gas from the "D" sand, common source of supply.

IT IS FURTHER ORDERED, that exceptions are hereby allowed for the following wells, and that each of said wells shall be the permitted oil or gas well for the drilling and spacing unit upon which it is located:

Shell Oil Company #1 Huldah A. Hanson
