Abstract
A coal seam producibility determination system may include a fiber optic cable, the fiber optic extending from a DAS interrogation unit into a wellbore. The DAS interrogation unit may be located at a surface. The wellbore may intersect a plurality of coal seams to be measured, the coal seams comprising fluid and solubilized gas. The wellbore contains wellbore fluid and the wellbore has a wall. The fiber optic cable extends along the plurality of coal seams. The coal seam producibility determination system may further include a spectrometer, the spectrometer located at the surface or within the wellbore. The coal seam producibility determination system may also include an optical window, the optical window in optical communication with the spectrometer, the optical window in fluid communication with the wellbore fluid.
