(the "WLR Area"). Within the WLR Area, operators may conduct drilling operations to the Niobrara Formation as follows:

i. Four (4) Niobrara wells may be drilled in any quarter section.

ii. No more than one (1) well may be located in any quarter quarter section.

iii. No minimum distance shall be required between wells producing from the Niobrara Formation in any quarter section.

iv. Wells shall be located at least 560’ from the outer boundary of said quarter section, and wells located outside any drilling units already established by the Commission in the WLR Area prior to this WLR’s effective date shall, in addition, be located at least 200’ from any lease line.

b. Any well drilled to the Niobrara Formation in the WLR Area prior to the effective date of this WLR which is legally located when this WLR becomes effective but is not located as listed above shall be treated as properly located for purposes of this WLR.

c. This WLR does not alter the size or configuration of any drilling units already established by the Commission in the WLR Area prior to this WLR’s effective date.

d. This WLR shall not serve to bar the granting of relief to Owners who file an application alleging abuse of their correlative rights to the extent that such Owners can demonstrate that their opportunity to produce from the Niobrara Formation at locations herein authorized does not provide an equal opportunity to obtain their just and equitable share of oil and gas from such formation.

e. Well exception locations to this WLR shall be subject to the provisions of Rule 318c.

f. This WLR is a well location rule and supercedes existing Commission orders in effect at the time of its adoption only to the extent that the existing orders relate to permissible well locations and the number of wells that may be drilled in a quarter section. Commission orders in effect when this Rule 318B is adopted nonetheless apply with respect to the size of drilling units already established by the Commission in the WLR Area. This WLR is not intended to establish well spacing. Accordingly, when an area subject to Rule 318B is otherwise unspaced, it does not act to space the area but instead provides the permissible locations for any new Niobrara Formation wells. Similarly, Rule 318B does not affect production allocation for existing or future wells. An operator may allocate production in accordance with the applicable lease, contract terms or established drilling and spacing units recognizing the Owner’s right to apply to the COGCC to resolve any outstanding correlative rights issues.
