Methods including introducing a treatment fluid into a wellbore in a subterranean formation, wherein the subterranean formation includes a coal seam gas reservoir, a freshwater reservoir, and formation laminae interposed therebetween, and the wellbore penetrating each, and wherein the treatment fluid comprises an aqueous base fluid and an aqueous curable resin; penetrating at least a portion of the formation laminae with the aqueous curable resin while maintaining the treatment fluid in the wellbore at a pressure sufficient to prevent the flow of freshwater from the freshwater reservoir into the wellbore; curing the aqueous curable resin, thereby stabilizing the formation laminae; creating permeability pathways in the coal seam gas reservoir itself; removing the treatment fluid from the wellbore; recovering gas from the coal seam gas reservoir.

Stabilizing formation laminae in coal seam wellbores

Methods for determining whether to perform a stimulation treatment on a subterranean zone are disclosed. Process zone stress ('PZS'), indicative of a production potential of the subterranean zone, is determined, and a determination is made as to whether the PZS exceeds a preselected value. A PZS exceeding the preselected value may indicate a poor production potential, and a stimulation treatment of the subterranean zone may be avoided. As a result, a substantial cost saving associated with the avoided stimulation treatment may be realized.
