About the Leak-off Test on drilling operations:
A test to determine the strength or fracture pressure of the open formation, usually conducted immediately after drilling below a new casing shoe.
Initially, pumping fluid into the borehole results in volumetric compression of the drilling mud column and elastic expansion of the casing string plus rock around the borehole. As the pressure in the borehole increases, the leak-off pressure (LOP) is reached when the relationship between pressure increase and volume of fluid pumped deviates from linear. This occurs when fluid begins to diffuse into the formation at a more rapid rate as the rock begins to dilate. Generally, a LOT is a test that finishes immediately after LOP is reached.

Oil & Gas Apps for Mac OS X
Oil & Gas Apps for Mac OS X
A few years ago, we searched for applications in the area of oil and gas for Mac OS X and not found. Then, we develop these applications and we would like to share with friends.
We would like to share our portfolio with very low cost applications to drillers, tool pushers, engineers, chemists, students and other professionals in the petroleum industry. These are productivity tools helpful in drilling of oil wells.
These apps are completely interactive and allow users to define a wide variety of parameters for oil wells and unit system, save data, share them with friends.
These Apps are available on the Mac App Store, only.

Well Control Simulator for iPhone and iPod Touch 1.4
Now available on the App Store
Features:
Well Control Simulator Provides a graphical very useful tool for training of roughnecks, derrickmen, drillers, tool pushers, drilling engineers and students in the well control procedures.
– Interactive System: no pre-set methods;
– Ability to apply methods: Driller’s method, wait and weight, dynamic volumetric and static volumetric (lubricate and bleed);
– Capacities and Volumes;
– Hydraulics and Hydrostatics and critical pressures calculations;
– Behavior of the kick;
– Applied with subsea stack and surface stack;
Kick Model:
The model assumes that the kick starts as a single bubble and migrates upward as a single bubble from the bottom to the surface.
Notes:
- For simulation of drilling and kick detection, use another app “Drilling Simulator“.
- For simulation of leak-off test, use another app “Leak-Off Test Simulator“;
- For methods to control, use another app “Well Control Methods“;
- For kick tolerance calculations, use another app “Kick Tolerance“;
- For hydraulic calculations, use another app “Drilling Hydraulics“;
New in this update 1.4:
- Improved Stability;
- Improved Well Configuration;
- Improved the work with data files;
- Added button to reset kick
- Fix bug to reset fracture
