Abstract
A component of the hydrocarbon well system and a first supply line to the component can be isolated from other components of the hydrocarbon well system. The component and the first supply line can be pressurized to a test pressure with a test fluid. Then, a pressure and a temperature of the test fluid in the component that was pressurized can be measured over a period of time. The pressure and the temperature that were measured can be analyzed and a pressure integrity of the component can be determined based on the analysis.

A computer-implemented method for testing components of a hydrocarbon well system, comprising:
- isolating a component of the hydrocarbon well system and a supply line to the component from other components of the hydrocarbon well system;
- pressurizing the component and the supply line to a test pressure with a test fluid;
- measuring, over a period of time, a pressure and a temperature of the test fluid in the component that was pressurized;
- analyzing, by a processor, the pressure and the temperature that were measured for changes or absence of changes in the pressure, the temperature, or both the pressure and the temperature correlated to the state of the component's pressure integrity;
- and
- determining a pressure integrity of the component based on the analysis.
A device comprising:
- one or more processors;
- and
- a non-transitory computer readable storage medium comprising instructions that cause the one or more processors to perform a method testing components of a hydrocarbon well system, the method comprising:
- isolating a component of the hydrocarbon well system and a supply line to the component from other components of the hydrocarbon well system;
- pressurizing the component and the supply line to a test pressure with a test fluid;
