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

6) Is the proposed well density less than or equal to the well density in the previously
approved area?
Select YES if the proposed well density is less than or equal to the well density in the previously
approved area.
Select NO if the proposed well density is greater than the well density in the previously approved
area.
7) Does each proposed holding/unit contain production data in the applied-for
formation(s)/pool(s)?
Select YES if each holding or unit has at least one well with enough production history to allow
for the submission of volumetric reserves data that can clearly support the need for the requested
special well spacing in the applied-for formation(s) or pool(s). Additional production and
volumetric reserves information from producing wells in surrounding areas should also be
included to fully support an application. Large areas of application containing production and
volumetric data from only a limited number of wells maybe considered premature and could be
closed.
In areas where limited production data is available the applicant must provide geological
evidence to demonstrate the resource being present throughout the entire area of application and
the quality of the reservoir (i.e. geological cross sections, geological analysis and structural and
net pay isopach mapping).
Select NO if any proposed holding does not contain production data in the applied-for
formation(s)/pool(s).
8) Is the density of the oil 920 kg/m 3 or greater at 15ºC?
Heavy oil, as defined in Directive 017: Measurement Requirements for Upstream Oil and Gas
Operations, is “crude oil production with a density of 920 kg/m 3 or greater at 15ºC.” This crude
oil density incorporates most of the areas of east-central Alberta, where heavy oil production
operations normally occur. Heavy oil development typically requires higher well densities to
maximize recovery.
Select YES if the application is for heavy oil. You must attach a Fluid Analysis that contains an
analysis of the native reservoir fluid, which includes the density of the oil. If the proposed well
density is >2 wells per pool per quarter but does not exceed 4 wells per pool per quarter section,
the application will be registered in the nonstandard processing path. However, upon registration,
it will be reviewed for the appropriate processing pathway and may qualify as a standard path
application.
Select NO if the application is not for heavy oil.
9) Enter the proposed well density.
All holding/unit applications must propose a well density. Well density is defined as the number
of wells per pool per area. Enter the well density and then select the well density area. Possible
well density areas are
• 1 Legal Subdivision
• 2 Legal Subdivisions
• 1 Quarter Section
• 1 Half Section
