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

3) The applied-for well density must be less than or equal to the approved well density.
4) Proposed well densities must be no more than two wells per pool per quarter section for
oil and four wells per pool per section for gas.
5) Standard buffer zones must be proposed.
Wells submitted in the application must have enough production history to allow for the
submission of volumetric reserves data that can clearly support the need for the requested
special well spacing throughout the entire area of application. Additional production and
volumetric reserves information from producing wells in surrounding areas should also be
included to fully support an application.
Figure 7.6. Standard application path
7.4.3 Nonstandard Application Path
Applications not meeting the quick or standard application path criteria are processed on the
nonstandard application path. Such applications typically propose complex or innovative
spacing requiring more detailed analysis. Production and volumetric reserves data should be
supplied from wells that have enough production history to allow for the submission of
volumetric reserves data that can clearly support the need for the requested special well
spacing throughout the entire area of application. These wells can be within and/or
surrounding the applied-for area.
In some cases the ERCB may find it necessary to gather more data to support the optimum
spacing for a resource. In such cases, an application may be approved as a test area and the
