A method and system for selecting fluids for compatibility with specified metals exposed to oil field environments. Metal specimens are tested for corrosion and/or cracking behavior by exposing them to fluids under stressful test conditions. The testing is conducted under variable temperature, pressure, pH, fluid density, metallurgical stress, additives, cover gases and combinations thereof. The results from the stress testing are stored in a database. The test results are evaluated using encoded logic embedded in software media. Fluid compatibility evaluation software, developed from the stress test results, is executed to determine the cracking susceptibility of metals exposed to fluids under stressful conditions. A cracking susceptibility index can be developed to provide a quantitative indicator of cracking susceptibility. Fluid recommendation reports utilize the cracking susceptibility index values to rank compatible fluids. The reports also list optional additives to be used with the fluids.
