Formation Integrity Test Procedure & Calculation
FIT or formation integrity test can be defined as the application of pressure by superimposing a surface pressure on a fluid column in order to determine the ability of a subsurface zone to withstand a certain hydrostatic pressure.

Why FIT?

The reason for performing the formation integrity test or formation competency test is to determine if a wellbore will support higher drilling mud weight so you can use the higher MWT in the next section.
