Abstract
A drilling fluid degasser having a weir to more evenly spread the drilling fluid over the leaves of the degasser to increase the efficiency of the degasser is disclosed. Additionally, a plurality of gas vent pipes are provided that ensure that once the gases are removed from the drilling fluid, the gases are removed from the degasser without contacting the drilling fluid to ensure the gases are not mixed into the drilling fluid again.
