Garrett
Gas Train with Case |
The Garrett Gas Train is the most widely used portable instrument for the determination of soluble sulfides and carbonate concentrations in drilling fluid. Soluble sulfides include
H2S and the sulfide (S-2) and bisulfide (HS-) ions. Total soluble carbonates include
CO2 and the carbonate (CO32) and bicarbonate
(HCO3) ions. Mud filtrate is acidified inside the gas train, converting all sulfides to
H2S or all carbonates to CO2, depending upon the test. The gas train separates the gas from the liquid and an inert carrier gas transports the gasses through the separate chambers. In chamber three, the gas stream is passed through a Dräger tube, which responds to
H2S or CO2 by darkening along its length, with the stain length proportional to the amounts of concentrations in the filtrate. For qualitative
H2S analysis, lead acetate paper disks may be inserted to determine the presence or absence of sulfides. The OFITE Garrett Gas Train consists of a transparent train, pressure regulator assembly,
CO2 and N2O cartridges, Dräger tubes for H2S and carbonate detection, and a convenient carrying case. For determining active sulfides in oil-based fluids, OFITE offers a separate kit that analyzes whole mud samples.
