Directive 065: Resources Applications for Oil and Gas Reservoirs ...

Oil
The baseline well density for oil is one well per pool per standard DSU, except that for
• the Mannville Group in Schedule 13A, the baseline well density is two wells per pool per
standard DSU.
Figure 7.2. OGCR Schedule 13B
The standard DSU size of one section for gas wells and one quarter section for oil wells
remains the same regardless of the baseline well density.
A block on land containing multiple, contiguous DSUs of common ownership as defined in
Section 1.020(2)(4) of the OGCR may be developed without a special well spacing approval,
limited only by the standard target area on the external boundaries of that block of land, as
long as the baseline well density per DSU is not exceeded for that area or strata. Figures
showing examples of development on multiple contiguous DSUs of common ownership can
be found in Appendix L.
