The EPA estimates that coal mines worldwide emitted 589 million tons of CO2-equivalent greenhouse gases in 2010. By 2030, that emission rate is expected to increase by 33 percent. The third generation of WellDog’s GasMapper coal gas assessment services enables coal mine operators to quickly and accurately identify where carbon dioxide and methane occur in coal seams targeted for mining so they can reduce fugitive greenhouse gas emissions, increase mine worker safety and enhance production of clean burning natural gas.
GasMapper is a downhole technical measurement service that evaluates the carbon dioxide and methane outburst, explosive and atmospheric emission risks for coal mines and informs coal mine operators on pre-drainage of the coals in order to reduce or eliminate those risks. WellDog’s third generation service involves a miniaturized Raman sensor and improved tubing joint sealing process, allowing the measurement system to be deployed reliably in slim boreholes.
Commercialization of the slimhole service follows a multi-year, multi-million dollar development effort at the company’s Reservoir Technology Center in Laramie, Wyoming. WellDog launched the GasMapper service in 2012.
