...Abstract Laboratory testing of corrosion inhibitors under high temperature high pressure (HTHP) conditions is challenging. HTHP testing has been traditionally performed in closed systems with fixed liquid/gas volume and testing results are usually influenced/compromised by the accumulation...

.... Such a study is motivated by the fact that even though for HPHT application if the temperature is higher than 107°C, a drop of the temperature can be encountered for instance in case of well shut-in. Experimental Procedures Materials Abstract High Pressure and High Temperature wells are very critical...

... been confirmed experimentally. Stress corrosion cracking might be an issue combining the oxidation occurring in sCO₂ and the high pressure present, leading to accelerated crack growth of a susceptible material due to its microstructure. All martensitic stainless steel specimens (plain...

...Abstract 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...
