    Hi –
    I just downloaded your spread sheet. Thanks very much for providing this to the industry. I work in Drilling Integrity and Well Design. I noted that the kick tolerance calculation is not correct when calculating a swab kick. If you set up parameters to model a swab kick, it will have an output value. IF you increase the mudweight, the KT volume increases, which is incorrect. In reality, when you drill deeper or increase your mud density, the KT volume reduces. This is a very common problem with KT calculators. Most of them are wrong for modelling a swab kick. These are the inputs I used:
    5,500
    9,500
    11.0 FP

    12.0 MW
    0.11
    14.7
    8.5
    5.0
    6.5
    500.0
    If you increase the MW from 12.0 to 13.0 the MAASP correctly reduces, but the actual volume increases.

    If you want any help with this, please let me know.

    Kind regards,
    Randy
