WellDog (trade name of Gas Sensing Technology Corp.) is a privately held company that uses innovative technologies to evaluate in situ the geochemistry and geophysics of unconventional hydrocarbon reservoirs, resulting in increased gas production as well as reduced costs and environmental impact for clients. Ten years ago, the principals of WellDog began using Raman spectroscopy to create a tool capable of measuring gas content in coalbed reservoirs. Along the way, they pioneered advances in spectrometer miniaturization, harsh environment sensing, coalbed reservoir simulation, and coalbed reservoir geochemistry.
