2. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...

3. Spectral noise logging - Wikipedia

   en.wikipedia.org/wiki/Spectral_noise_logging

   Over many years, downhole noise logging tools proved effective in inflow and injectivity profiling of operating wells, [3] [4] leak detection, [5] [6] location of cross-flows behind casing, [7] and even in determining reservoir fluid compositions. [8] Robinson (1974) described how noise logging can be used to determine effective reservoir ...

4. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   Tubing inspection is generally limited to non-ferromagnetic tubing and is known as conventional eddy current testing. Conventional ECT is used for inspecting steam generator tubing in nuclear plants and heat exchangers tubing in power and petrochemical industries. The technique is very sensitive to detect and size pits.

5. Magnetic flux leakage - Wikipedia

   en.wikipedia.org/wiki/Magnetic_flux_leakage

   Magnetic Flux Leakage inline inspection tool (MFL-ILI) has been in use the longest for pipeline inspection. MFL-ILIs detect and assess areas where the pipe wall may be damaged by corrosion. The more advanced versions are referred to as "high-resolution" due to their increased number of sensors.

   LD – lay down (such as tubing or rods) LDAR – leak detection and repair; LDHI – low-dosage hydrate inhibitor; LDL – litho density log; LDS – leak detection system (pipeline monitoring) LDTEP – LDT EPT gamma ray log; LEAKL – leak detection log; LEPRE – litho-elastic property report; LER – lands eligible for remining or land ...

7. Leak noise correlator - Wikipedia

   en.wikipedia.org/wiki/Leak_noise_correlator

   A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines.. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.
