and such area shall henceforth be known as the Ignacio Fruitland-Pictured Cliffs Field.

Rule 2. No well shall be drilled and completed or recompleted in the said formation or pool, and no notice of intention to drill shall be approved by the Commission unless:

(a) Such well be located on a designated drilling unit of not less than 320 acres of land, more or less, according to legal subdivisions of the United States Land Surveys in which unit all of the interests are consolidated by a pooling agreement or otherwise and on which no other well is completed or approved for completion in the same pool.

(b) Such drilling unit be in the shape of a rectangle, except for normal variations in legal subdivisions of the United States Land Surveys, the North Half (N/2) South Half (S/2), East Half (E/2), or West Half W/2) of each section constituting the drilling unit.

(c) Such well be drilled no closer than Nine Hundred Ninety (990) feet to the boundaries of the quarter section upon which it is located.

(d) Such well, if drilled to the Ignacio Fruitland-Pictured Cliffs pool, be located in either the Northwest Quarter (NW/4) or Southeast Quarter (SE/4) of the section on which it is located, unless such well was completed prior to the date of this order.

Rule 3. The Commission may, by order entered after due notice and hearing, and to prevent waste or confiscation of property, or to prevent inclusion of unproductive land in a drilling unit, grant exceptions to the provisions of Rule 2 above, and the Commission may, without additional notice and hearing, grant exceptions to Rule 2 (c) above, when, because of topographical reasons, it is necessary to locate such well closer than Nine Hundred Ninety (990) feet to the boundaries of the quarter section in which the well is drilled.

Rule 4. The casing program of all wells hereafter drilled in the Ignacio Fruitland-Pictured Cliffs pool shall include at least two (2) strings of casing which shall be set in accordance with the following:

(a) The surface casing shall consist of new or reconditioned pipe with the original mill test of not less than 1200 psi and shall be set and cemented at a point such that all fresh water and water of present or probable value for domestic, commercial or stock purposes shall be confined to their respective strata and shall be adequately protected against contamination by objectionable water, oil or gas, provided that the point at which the surface casing shall be set and cemented shall in no case be less than 200 feet below the surface of the earth. Cementing shall be by the pump and plug method and sufficient cement shall be used to fill the annular space behind the pipe to the surface of the ground or the bottom of the cellar. Cement shall be allowed to stand a minimum of twenty-four (24) hours before drilling the plug or initiating tests. Before drilling the plug, a pump pressure of at least 1,000 psi shall be applied. If at the end of thirty (30) minutes the pressure shows a drop of 100 psi or more, the casing shall be condemned. In lieu of the foregoing test the surface casing shall be tested after drilling the plug by bailing the hole dry. The hole shall remain dry for one (1) hour to constitute satisfactory proof of a water shutoff. In event the casing is condemned, it shall again be tested in the same manner after corrective operations are completed and this string shall stand the required test before compliance with this rule shall have been made.

(b) The producing or oil sting shall consist of new or reconditioned pipe with an original mill test of not less than 2000 psi. This string of casing shall be set and cemented at such a point that all oil, gas, and water encountered above the producing formation and below the surface casing shall be adequately confined to their respective strata. Cementing shall be by the pump and plug method and the volume of cement used shall be that calculated to bring the top of the cement 600 feet above the highest formation which is indicated to be commercially productive of oil or gas. The cement shall be allowed to stand a minimum of twenty-four (24) hours before drilling the plug or initiating tests. Before drilling the plug a pump pressure of at least 1500 psi shall be applied. If at the end of thirty (30) minutes, the pressure shows a drop of 150 psi or more, the casing shall be condemned. In lieu of the foregoing test the surface casing shall be tested after drilling the plug by bailing the hole dry. The hole shall remain dry for one hour to constitute satisfactory proof of a water shutoff. In the event the casing is condemned, it shall again be tested in the same manner after corrective operations are completed and this string shall stand the required tests before compliance with this rule shall have been made.

IT IS FURTHER PROVIDED, that any operator or operators owning oil and gas leases upon lands contained within the boundaries hereinabove defined and desiring to drill a well or wells thereon, shall, by pooling agreement or otherwise, form a Three Hundred twenty (320) acre unit, or units, in conformity with the spacing pattern herein established, provided that the rights of all parties affected hereby to apply to the Commission for the formation of a 320-acre unit or units under the provisions of Chapter 230 of 1951 Session Laws of the State of Colorado shall not be prejudiced by the entry of this order; and provided that, in the event of the proposed formation of a 320-acre unit to conform with the spacing pattern herein established which contains patented lands and Indian lands, if the Department of Interior fails to approve such unit, then the patented lands therein shall not be affected by the terms and requirements of this order, other than Rule 4 above.

IT IS FURTHER ORDERED, that the rules and regulations contained herein shall become effective forthwith, and henceforth the commencement of the drilling of any well or wells in the Fruitland-Pictured Cliffs pool of the Ignacio Field, as defined herein, for the purpose of producing gas therefrom at a location other than authorized by this Order, is hereby prohibited.

IT IS FURTHER ORDERED, that the Commission expressly reserves its right, after notice and hearing, to alter, amend, or repeal any and/or all of the above rules and regulations.

ORDERED this 13th day of July, 1955.
