Kick tolerance worksheet, release 9, issued 19 August 2013. WORK version.(updated and simplified)Kick tolerance definition; "A description of the volume and pressure of a gas influx that can be safely circulated out of thewell".
This worksheet calculates the volume of an influx taken from drilling into an overpressured formation that can be circulated out ofthe well without exceeding the assumed or tested strengths of the formations exposed just below the casing shoe. It does notaccount for gas migration or dispersion in the mud column and it also assumes that no heavy mud exits the bit before the top ofthe influx reaches the casing shoe. These calculations should not be used for diverter drilling, slimhole drilling (

Version 1 of this worksheet was released on 12 February 2008.
Version 6 was released after correcting the conversion factor for kPa/m.
Version 6a was changed for the JIT version, to display intermediate results in both metric and imperial units.
Version 6b was released after revising the variable names in line with the new DDC convention.
Version 6e was released after adding a specific warning if a negative kick intensity is used.
Version 6f was released after adding some more information in the Results.
Version 7 was released after correcting a small error, to account for any safety margin pressure in calculating the influx volume on bottom.
Version 8 was released after realising that there was a much easier way to calculate kick tolerance!
Version 9 corrected an error when calculating for hole inclination at the casing shoe.
