The following formula is the kick tolerance factor.

Where;

Casing shoe TVD in ft

Well depth TVD in ft

Maximum Allowable MW in ppg

Current MW in ppg

**For more understanding, let’s try to calculate the kick tolerance factor (KTF) using the following information:**

Casing shoe TVD = 5000 ft

Well depth TVD = 11,000 ft

Maximum Allowable MW = 12.9 ppg

Current MW =9.8 ppg

According to the equation above, you will be able to calculate like this;

Kick Tolerance Factor =1.41 ppg
