Bubble Test is primarily used for testing of oil field inhibitors using the Bubble Test technique. Other names for this test include the Kettle Test and Inhibitor Screening. They are all tests that use the LPR technique with respect to time to calculate the efficiency of oil field inhibitors.
A series of LPR tests are collected over time, giving Corrosion Rate results. Cells (or Channels) are assigned together into Groups, each group has an Add Inhibitor button, once pressed, corrosion rates can be calculated for 3 periods - prior to Add Inhibitor, after 2 hours and after 16 hours (configurable), this enables Percentage Protection to be calculated
The standard Bubble Test uses a series of Linear Polarization Tests over a period of about 24 hours to assess the performance of a corrosion inhibitor. In simple terms it does not give an indication of localized corrosion. However, up to 80% of pipeline failures are ascribed to pitting, but very few monitoring methods are capable to show this outcome. LCM™ attempts to give the user this information as well as the standard Bubble Test information. The test preparation and duration is the same as for a standard three electrode Bubble Test using an Auxiliary, Corrosion Resistant Reference and Test Electrode. The standard Bubble Test data is achieved with or without the addition of LCM™. LCM™ just gives additional information relating to the magnitude and frequency of pitting events.
