METHANE ASSESSMENT & MITIGATION

LTE has extensive experience in conducting methane assessment surveys associated with coal outcrops, leaking production wells, pipelines, and landfills in Colorado and the Rocky Mountain region, including Texas, Wyoming, and Utah. Using our state-of-the-art portable accumulation chamber, LTE can delineate areas of fugitive methane gas seepage and quantify flux rates over areas ranging in size from a small pipeline leak to seepage at the ground surface over 50 square miles of coal outcrop. LTE can define the extent of impact from methane seepage; assess the risk associated with the accumulation of methane in water supply well systems and structures (i.e., basements, well sheds, garages, commercial and residential buildings); and conduct forensic analyses of geochemical parameters to identify sources of gas.

Not only is LTE an expert at assessing methane seepage from the ground surface or the accumulation of methane in structures, LTE’s engineers have designed, installed, and operated the only methane mitigation system that can capture gas from a coalbed seep, generate electricity, and transfer the electricity to the local power grid. In addition to seep mitigation engineering, LTE has extensive experience in the design and installation of mitigation systems to protect structures using detection alarms; systems that can passively or actively vent structures; engineered vapor barriers; and water well treatment systems to removed dissolved methane and free gas entrained in the water supply.

LTE is well-equipped and experienced to provide compliance with Colorado Oil & Gas Conservation Commission (COGCC) Rule 608 (Coalbed Methane Wells) for oil and gas clients in Colorado. In fact, much of LTE’s techniques developed in conducting methane seep assessments and water well sampling in the San Juan Basin formed the basis for the techniques described in COGCC Rule 608.

 

Flux Meter

We also have experience in using alternate assessment tools and strategies including: infrared imagery acquisition and field verification of suspect areas; soil gas surveys; light detecting and ranging (LIDAR) systems; installation of soil vapor tubes; sampling of monitoring wells and water supply wells; and permanent flux chamber installation and monitoring. Our staff is experienced in utilizing several types of diagnostic field equipment for detecting methane including combustible gas meters, four-gas meters, landfill gas meters, flux meters, flame-ionization detectors, photo-ionization detectors, and Draeger® sampling tubes.
