Abstract
The Bureau of Mines made laboratory absorption measurements on oil shale samples, which showed that the amount of methane absorbed is porportional to pressure and oil yield, and can be much larger than would be predicted based solely on porosity. Oil shale cores collected in the field were also measured for their gas content using the Bureau of Mines direct method. Cores taken from deep locations and far from outcrops yielded more gas than cores from shallower locations or at outcrops, when taking into account variations in oil yield, and all data indicate that oil shale mines that are both deep and far from an outcrop will emit low levels of methane gas.
