Abstract (en)
[origin: WO2004003506A2] A measuring system for in-situ measurements down a well by a spectrometer is provided. The spectrometer includes a radiation source and a detector. A probe is optically connected to the spectrometer and includes an optical pathway for transmission of a radiation from the radiation source and at least a second optical pathway for transmission of a characteristic radiation from a sample to the detector. A positioner is provided to position the probe near a side surface of the borehole and to optically couple the optical pathways to the side surface, wherein the probe is traversable up and down the well by way of a guide operatively connected to the probe and to a fixed location at the wellhead. By use of the apparautus and method a concentration of methane or other substance of interest is obtained, and thereby, a potential production of a coal bed methane formation is obtained.
