Kick Tolerance Calculation

This post will teach you how to calculate kick tolerance. This concept is very important to well design and will give you an idea how much kick you can take at particular parameters.

Firstly, I would like to be clear about the following terms;

Kick tolerance is the maximum gas influx volumes (bbl) for a designed kick intensity that can be successfully shut the well in and circulated out without breaking formation pressure at the casing shoe.

Kick intensity is the different between the maximum anticipated formation pressure and planned mud weight.

Secondly, learn how to determin kick tolerance by following steps below:

Directional Drilling Calculation Example

I got the question from my friend, Nien, asking me about directional drilling calculation and the question is shown below:

Wellplanner is planning to design a deep kick-off well with a build section to by pass a salt dome section. He intends to achieve a horizontal departure of 1500 ft at the with the TVD at the target point to be 10,000 ft. Calculate the measure depth and build up rate.

Kick Tolerance Factor Calculation

The following formula is the kick tolerance factor.

Kick Tolerance Factor Formula
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:
