Coalbed Methane (CBM):


CBM projects will require the dewatering of coal seams to assist with methane production. If the groundwater is saline (> 4,000 ppm total dissolved solids (TDS)), Alberta Environment (AENV) authorization is not required.

If the project requires the diversion of non-saline groundwater (< 4,000 ppm TDS) from the coal seam, AENV authorization is required, and the Guidelines for Groundwater Diversion for CBM Development must be followed.

  A) Complete a Preliminary Groundwater Assessment Report, including:
  right arrow A description of the CBM investigation
  right arrow The results of a field-verified water well survey
  right arrow A detailed assessment of the geology of the project area
  right arrow A description and discussion of the hydrogeologic conditions of the project area
  right arrow A conceptual Water Management Plan
  This report must be submitted to and approved by AENV prior to drilling / re-completion or groundwater diversion.

  B) Complete a technical report supporting an Application Under the Water Act, including:
  right arrow An overview of the existing hydrogeologic information supported by field-verified water well survey data
  right arrow Aquifer testing data
  right arrow Groundwater quality data
  right arrow An operational Water Management Plan
  right arrow A cumulative impact assessment
  right arrow Groundwater monitoring data and recommendations

HCL has prepared and submitted hundreds of technical reports to AENV to support groundwater diversions in Alberta.
