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

production data for each applied-for formation are required. Applicants must edit the
producing formation and/or producing pool when a commingled pool name is populated.
Applications in which this information is not edited will be closed.
For commingled wells, the same UWI can be used by selecting the same well licence number
multiple times to provide production/volumetric data that can be allocated to each specific
producing formation within a well. (See Section 7.3.3.1: Commingled Production.)
If selecting a confidential well to support an application, all production/volumetric
information must be provided. All confidential data provided in support of an application are
public and viewable in IAR Query.
For each well used to provide production information, the following data must be provided
where applicable:
• well licence number
• unique well identifier
• producing formation
• producing pool
• well status
• on-production date
• last date the well reported production
• the depth to the top of the first perforation
• the depth to the bottom of the last perforation
• the true vertical depth from the kelly bushing (KB) to the top of the first perforation
• the true vertical depth measured to the bottom of the last perforation
• initial operated-day rate based on actual hours of the first month in which oil/gas is
produced
• last operated-day rate
• last calendar-day rate based on calendar days in the month in which oil/gas was last being
produced
• current ratio of water production to gas production (WGR)
• cumulative gas/oil production
• cumulative water production
• cumulative condensate production
For wells for which volumetric reserves information has been provided, a production plot and
decline analysis for each well is required. The analysis must include an explanation of the
parameters used to populate the volumetric form (e.g., the net pay used is from the XX/XX-
XX-XXX-XXWX well that is in the area of application).
If the number of wells per area calculated on the volumetric form is less than the well density
requested, the following warning message appears: “The UWI shows a ‘max number of wells
per area’ less than the requested well density in the application. Confirm your values before
saving.” This information message asks you to review your data and perhaps change the well
density request or provide additional supporting information. A written justification for the
submitted production and volumetric data must be included with the application.
Table 7.2 describes the fields on the Production and Volumetric Form and the values to be
entered.
