Corrosion testing routinely involves testing brine and hydrocarbons under high temperature and high pressure (HTHP) in the presence of CO2 and H2S. One common laboratory procedure is heating a pressure vessel to the test temperature and loading the gases at these conditions. This process involves many inefficiencies and hazards that can be mitigated by loading the gases prior to heating. This modified process requires complex calculations using the volume and mass balance of the target test environment.

In this paper the charging procedure will be demonstrated. Two case histories will be shown including autoclave telemetry data (pressure and temperature) and other pressure measurements taken at temperature which illustrate the utility of this method and the correlation with calculated and experimental values. The paper will also discuss the advantages and disadvantages of using such a method for corrosion testing.

Key words: gas charging, high temperature, high pressure, aqueous simulation, fugacity, partial pressure, corrosion testing, CO2, H2S.
