A gas probe is coupled to a lower end of the drill string. The method also includes opening the gas probe to collect the gas from the subsurface formation. The method also includes drawing the gas up through the drill string after the gas probe is opened. The method also includes measuring the hydrogen concentration of the gas after the gas is drawn up.
