Kick Tolerance for Mac OS X Lion

(iMac, Macbook and Macbook Air)

Awaiting for approval by Apple

The Kick Tolerance provides to drilling engineers, chemists, technicians, students and others professionals in the Oil & Gas industry a productivity tool helpful in drilling operation (well control) and planning phase of oil wells.

This application deals with two concepts:

1- Kick Tolerance as Maximum Pore Gradient;
2- Kick Tolerance as Maximum Kick Volume.

Both with graphical analyzes.

For both the concepts, the calculations uses the Fracture Gradient defined in “Well Configuration -> Gradients” views.

For KT as Maximum Pore Gradient:

– Plot KT x Maximum Kick Volume

KT (Maximum Pore Gradient) = mudWeight + (casingShoe/wellDepth) * (fractGradWEq – mudWeight) – (KickLength/wellDepth) * (mudWeight – kickDensityWeq);

=> Known the Maximum Kick Volume, find the KT as the Maximum Pore Gradient;

For KT as Maximum Pit Gain Volume:

Plot KI = the difference ( Pore Gradient – Mud Weight ) versus Maximum Kick Volume (Pit Gain)

KI (Pore Gradient – Mud Weight)
= (casingShoe/wellDepth) * (fractGradWEq – mudWeight) – (KickLength/wellDepth) * (mudWeight – kickDensityWeq);

=> Known the difference (Pore Gradient – Mud Weight), find the Kick Tolerance as Maximum Kick Volume.
