whenever you are drilling through the pay zone, gas contained zones or shallow gas zones there is the risk of having gas in the mud. As you are circulating the mud throthe annulus if the hydrostatic pressure of the column of mud in the annulus is less than the formation pressure then the gas will rise. Note that the gas can be contained in the mud which is called gas cut mud.
