WellDog Detector

WellDog’s proprietary technology uses Raman spectroscopy, a chemical sensing technique used in chemical, pharmaceutical, and medical applications, as well as in academic laboratories.  The Raman effect, which is the inelastic scattering of light, was first identified in 1928 and named after one of its discoverers, Sir C.V. Raman.  Raman won the Nobel Prize in Physics in 1930 for this discovery.  Raman spectroscopy became widely used after the invention of the laser.

WellDog’s patented technology utilizes a laser and sophisticated optics to analyze wellbore fluids.  A sample is illuminated with a laser beam, and the scattered light is collected and analyzed to identify the chemical bonds. Chemicals in the tested fluids or formations produce Raman "signatures", which allow very specific identification.  In addition, the Raman signal intensity is directly proportional to the concentration of the measured chemical, or in WellDog’s application of this technology, the measured gas concentration in the wellbore fluids.
