5. In order to prevent waste of oil and gas as defined by law; to protect the correlative rights of all parties concerned; to prevent the drilling of unnecessary wells, and to insure proper and efficient development and promote conservation of the oil and gas resources, an order should be made establishing 80-acre, more or less, drilling and spacing units for the production of oil and associated hydrocarbons from the D' Sand formation, a common source of supply underlying the lands described herein; that the units should consist of 80-acres, more or less, and consist of the E/2 and W/2, or the N/2 and S/2, of a governmental quarter section, with the unit described by the operator of the first well drilled in the quarter section. The permitted well for each unit should be located in the center of the NW/4 and the SE/4 of each quarter section with a tolerance of 200 feet in any direction. Well No. 15-5 Bringleson, located in the SW/4 SE/4 of said Section 5 and well No. 7-10 Federal, located in the SW/4 NE/4 of said Section 10 should each be considered exceptions and be the permitted well for the unit to be designated by the operator. Exceptions to the permitted well locations may be granted by the Director, provided owners of the contiguous and cornering units file a waiver or consent in writing agreeing to such exception.

6. All available geological and engineering data concerning said "D" Sand formation indicates that one well will efficiently and economically drain an area of approximately 80-acres, more or less, and that the drilling units of the size and shape hereinabove described are not smaller than the maximum area that can be efficiently and economically drained by one well producing from said D' Sand formation.
