7.4.6 ERCB Spacing Application Decision Tree<br />
Figure 7.7 outlines the ERCB decision process <strong>for</strong> holding applications.<br />
Question 1<br />
Does your area of application include entire DSUs?<br />
Yes<br />
Question 2<br />
Does each applied-<strong>for</strong> holding have common ownership at the lessor <strong>and</strong><br />
lessee level?<br />
No<br />
The<br />
application<br />
cannot be<br />
filed.<br />
Yes<br />
Question 3<br />
Question 5<br />
Is each applied-<strong>for</strong> holding/unit<br />
adjacent to a previously approved<br />
area <strong>for</strong> the same <strong>for</strong>mation(s)/<br />
pool(s)?<br />
Yes<br />
Question 4<br />
Does every DSU in each applied<strong>for</strong><br />
holding/unit have an adjacent<br />
DSU with approved spacing <strong>and</strong><br />
production data?<br />
No<br />
No<br />
Is any part of each applied-<strong>for</strong><br />
holding/unit within 3 st<strong>and</strong>ard<br />
DSUs of a previously approved<br />
area <strong>for</strong> the same <strong>for</strong>mation(s)/<br />
pool(s)?<br />
Yes<br />
Question 7<br />
Does each proposed holding/unit<br />
contain production data in the<br />
applied-<strong>for</strong> <strong>for</strong>mation(s)/pool(s)?<br />
No<br />
No<br />
Limited data<br />
may mean the<br />
application is<br />
premature.<br />
Yes<br />
Yes<br />
Question 6<br />
Is the proposed well density less than or equal to the well density in the<br />
previously approved area?<br />
No<br />
Yes<br />
Question 9<br />
Yes<br />
Is the proposed well density less than or equal to 4 wells per pool per section<br />
(gas) or 2 wells per pool per quarter section (oil)?<br />
No<br />
Question 8<br />
Is the density of the oil 920 kg/m 3<br />
or greater @ 15 C?<br />
Yes<br />
No<br />
Yes<br />
Question 10<br />
Yes<br />
Yes<br />
Question 9<br />
Is the proposed well density less<br />
than or equal to 4 wells per pool<br />
per quarter section?<br />
No<br />
Is the applied-<strong>for</strong> buffer zone equal to the st<strong>and</strong>ard buffer zone <strong>for</strong> the area<br />
of application <strong>and</strong> production source as specified in <strong>Directive</strong> <strong>065</strong>?<br />
No<br />
Yes<br />
Application may be<br />
Quick<br />
Yes<br />
Application may be<br />
St<strong>and</strong>ard<br />
Application is<br />
Nonst<strong>and</strong>ard<br />
St<strong>and</strong>ard buffering <strong>for</strong> oil<br />
100 m on all boundaries of the holding(s).<br />
St<strong>and</strong>ard buffering <strong>for</strong> gas<br />
Outside 13A: 150 m on all boundaries of the holding(s).<br />
13A: 150 m on the south <strong>and</strong> west boundaries of the holding(s).<br />
