WellDog is a privately held company focused on using innovative technologies to improve exploration and production of oil, gas and alternative energy resources.

WellDog started as an effort in early 1999 to develop a Raman spectrometer capable of detecting trace hydrocarbons effluent from gas hydrates that occur naturally in the deep ocean. That same year, the company began to apply its platform sensing technology to solve key challenges in coalbed methane exploration and production.

Today, the company is a leading provider of innovative, integrated technical services and products to the unconventional oil and gas, mining, and alternative energy industries.
