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

An apparatus and method to determine fractions of various phases in a multiphase fluid. The apparatus includes main body including an interior configured receive a multiphase fluid and an exterior. The apparatus senses fluid pressure of multiphase fluid received in the interior and senses a fluid temperature of the multiphase fluid. The apparatus transmits an ultrasonic wave into the fluid and detects the transmitted wave to determine its velocity and attenuation. The apparatus may adjust the determined velocity and attenuation based on the temperature and pressure of the fluid to compensate for a difference between the sensed temperature and pressure and a standard temperature and pressure. The apparatus determines a gas fraction, water fraction, and a non-water fluid fraction of the multiphase fluid based on the sensed fluid pressure, the sensed fluid temperature, and the velocity and attenuation of the ultrasonic wave in the multiphase fluid.
