Abstract
A degasser system may comprise a mass flow controller device and a sample pump coupled to a sample degasser for controlling the dilution of gases extracted from drilling fluid in the sample degasser by a dilution fluid, such as nitrogen gas. The mass flow controller may inject the dilution fluid into the tank of the sample degasser to dilute the gases extracted from the drilling fluid. The dilution fluid may be aspirated or sparged into the sample degasser. The sample pump may extract a sample of the gases separated from the drilling fluid by the sample degasser. The rate of injection of the dilution fluid into the sample degasser and the rate of extraction of the gas sample from the drilling fluid may be adjustable to control the dilution of the gas sample for analysis.
