Fracture stimulation or "fracturing" of coals is the injection of fluids at high pressure down a well bore into existing cracks (fractures) in the coal seams.  The process is used to widen the passage-ways to allow the gas to flow more freely and enhance production.  Without fracturing, the gas is more difficult to produce and the well may not be viable. Fracturing is a well-understood and widely-used technology in coalbed methane wells.

Fracturing Propagation Schematics Per Area
The links below provide fracturing schematics for many of Quicksilver’s areas of operations in Canada.  The schematics portray characteristics for each area, including approximate coal depths and thickness, typical fracture geometry and typical water well depths.  For a generalized reservoir schematic please click here.
