How much water is produced with a CBM development?
• It depends on where the development is occurring. Production data indicates the three main CBM targets in Alberta have different water production characteristics. • Wells completed in the Horseshoe Canyon are mostly dry. This is the area where industry has concentrated most of its activities. • Wells completed in the deep Mannville coals produce water that is saline. • The few wells completed to date in the more shallow Ardley coals have tested a mix of water characteristics; some produce no water, others produce slightly saline water and some produce non-saline water. • Any well producing non-saline water must have a water diversion approval from Alberta Environment.
