Purpose of this Directive
This directive details requirements and issues specific to the control well process and supersedes any previous AER publication on coalbed methane control well requirements.
A control well is established for the purpose of collecting pressure, productivity, and gas content information to allow for an understanding of gas resources in coals.
Note: For specific geological zones within a defined area, the AER may adapt subsurface directive requirements through a subsurface order to better suit the resource development practices being used.
