A possible petroleum related helium anomaly in the soil gas, Boulder and Weld Counties, Colorado

A survey of the concentrations of helium in the soil gas conducted over a portion of the Denver Basin in Boulder and Weld Counties, Colorado, supports the existence of a potential petroleum prospect that was suggested by earlier geochemical analyses of the outcropping sandstones. The helium survey technique may prove to be a rapid, inexpensive, and valuable surface prospecting tool for detecting buried petroleum deposits.
