A method for identifying a leak in a pressure system. The method includes receiving, from a pressure sensor, pressure data of a fluid contained in the pressure system, determining a slope and curvature of the pressure data, determining a ratio of the curvature to the slope of the pressure data, and monitoring the ratio over a period of time. The method also includes, as a result of a non-constant component of the ratio exceeding a predetermined threshold, generating an indication that a leak may be present in the pressure system, or as a result of the ratio including no non-constant component or a non-constant component below the predetermined threshold, generating an indication that no leak is present in the pressure system.

G01M 3/26 - Investigating fluid tightness of structures by using fluid or vacuum by measuring rate of loss or gain of fluid, e.g. by pressure-responsive devices, by flow detectors
A method includes receiving a result of a benchmark leak detection test for a pressure system and determining whether the result indicates that a leak is present in the pressure system. In response to the result of the benchmark leak detection test indicating that a leak is not present in the pressure system, the method includes performing a subsequent leak detection test for the pressure system, comparing a result of the subsequent leak detection test to the result of the benchmark leak detection test, and determining, based on the comparison, whether the subsequent leak detection test indicates that a leak is not present in the pressure system. A time to determine whether a leak is not present based on the comparison is less than a time to determine whether a leak is not present based on the benchmark leak detection test.

SYSTEM AND METHOD FOR IMPROVING PRESSURE TEST EFFICIENCY
A system includes a memory and a processor coupled to the memory. The processor receives a description of a pressure system, including a plurality of components to be tested, where each component has a required test pressure. The processor generates a first test sequence that tests the required test pressure of each of the plurality of components, where the first test sequence includes a first number of steps. The processor also iteratively generates a second test sequence that tests the required test pressure of each of the plurality of components, where the second test sequence comprises a second number of steps. The processor stores a representation of at least one of the first test sequence and the second test sequence in the memory, and the second number of steps is less than the first number of steps.
A method for determining the presence of a leak in a pressure system. The method includes receiving pressure data of the pressure system after shut-in of the pressure system, determining a pressure slope based on the pressure data, entering a passing state in response to the slope being less than a predetermined slope threshold, exiting the passing state in response to the slope being greater than the predetermined slope threshold, and generating a passing indication as a result of remaining in the passing state for at least a predetermined time period.
