Special projects with large independent oil and gas companies in the Piceance, Raton, Texas Gulf Coast, and Washakie Basins led to the following results:

• Truck mounted and pedestrian surveys identified threat to health and safety from large and numerous naturally-occurring  gas seeps.  Company decides to conduct routine soil gas surveys prior to building new pads.

• Truck mounted and pedestrian surveys identify large natural gas seeps from abandoned coal mines, coal seam outcrops, and spring discharge zones.  Regulatory agency decides to implement requirements for baseline soil gas surveys prior to drilling new wells around active and abandoned coal mine areas and outcrops.

• Pedestrian soil gas survey and gas analysis used to confirm gas sources from gas well blow out.  Additional gas seeps found during the investigation led to identification of separate stray gas sources from another producing well pad.  Report to state agencies, and testify at hearings.

• Truck mounted survey revealed leaking gas wells at a gas storage field.

• Truck mounted surveys identified air quality impacts from leaking surface production fittings, open tanks, distribution lines.

• Soil gas surveying equipment routinely deployed to detect and sample headspace gases in water wells.
